The Big Manistee River in northern Michigan is the most famous salmon water in the Midwest. From mid-August through October, kings push out of Lake Michigan and ascend the river to spawn. Tippy Dam — the upstream limit of fish migration on the river — concentrates them in numbers that draw anglers from across the country. The fall run is one of those bucket-list fishing experiences for serious salmon anglers.

This guide covers the Manistee fishery — when to go, where to fish, what techniques work, and what to bring. The river system fishes differently from typical trout streams, and the salmon are different from the open-water kings caught on Lake Michigan trolling. Pair with the king salmon temperature guide and the Lake Michigan calendar for seasonal context.

The Manistee River System

“The Manistee” typically refers to the Big Manistee River, but the system has several sections that fish differently:

• Lower Manistee (Manistee Lake to the Lake Michigan mouth) — Brackish-tidal water. Where fresh salmon first enter from the lake. Boat fishing dominant.
• Manistee Lake — The widening near the city of Manistee. Mixed-species water, including salmon staging before pushing upstream.
• Big Manistee River (Manistee to Tippy Dam) — The classic salmon river. About 25 miles of fishable water with multiple access points.
• Tippy Dam pool and tailrace — Where fish concentrate against the upstream limit. The most famous and most-pressured water on the system.
• Tippy Dam to Hodenpyl Dam (Upper river) — Above the salmon run. Holds resident trout, browns, and steelhead but salmon can’t reach this water.

When to Fish the Manistee

The Manistee run is more compressed than the Salmon River run on Lake Ontario:

For king salmon specifically, the second week of September through the first week of October is peak. After that, the kings are heavily into the spawn and the bite turns selective. Coho and steelhead continue to push in through October and beyond.

Tippy Dam

Tippy Dam is the upstream limit for migrating Lake Michigan salmon. Built in 1918 for hydropower, it’s about 35 river miles up from Manistee. The dam concentrates all upstream-bound fish in a relatively small pool, which makes it the most famous and most-pressured single fishing spot in the Midwest during the fall run.

The dam pool itself, and the immediate tailrace below it, holds thousands of staged salmon during peak migration. Access is excellent — Consumers Energy maintains parking lots, paths, and shore access on both sides of the dam. The downside: at peak, you’ll fish shoulder-to-shoulder with hundreds of other anglers.

Tippy Dam fishing strategies vary by water level. When the dam is releasing significant water (typical for power generation), strong current concentrates fish in specific seams and current edges. When releases are low, fish spread throughout the pool. Pay attention to the release schedule — knowing whether the dam is “on” or “off” changes your strategy significantly.

Lower River and Manistee Lake

The lower river — from Manistee to about Brethren — is the alternative to Tippy Dam pressure. Fish here are fresh from the lake, often still bright chrome, and feed more aggressively than the dark, spawn-mode fish in the upper pool. Less pressure, harder access for shore anglers, but excellent boat fishing.

Manistee Lake is the widening between the river and the harbor. Fish stage here before pushing upstream. Boat anglers troll the lake with downriggers in shallower-than-usual setups, sometimes finding kings in just 20–40 feet of water. Combined trolling and casting tactics produce.

Techniques for Manistee Salmon

Drift Fishing with Kwikfish or Mag Lip Plugs

Drift fishing with a wrapped plug is the dominant boat technique on the Manistee. A Kwikfish K15 or Yakima Mag Lip 3.5 wrapped with a sardine wrap is the standard. The plug drifts downstream with the current, the wobble triggers strikes from staged kings. Boat anglers position upstream of holding water, let the plug back into the strike zone, and wait for the hit.

Spinner and Spoon Casting

Shore anglers cast spinners and spoons through holding water. Mepps Aglia spinners in #4 or #5 are the classic choice. Acme Kastmaster 1 oz spoons cast across the river to reach far structure. The retrieve should be slow — let the current carry the lure across the holding water rather than retrieving aggressively against it.

Stickbait Casting

In slower water and lower light, Rapala Husky Jerks produce. The suspending action lets you twitch the lure through staged fish without spooking them. Particularly effective on coho and pre-spawn kings.

Bead and Glo Bug Fishing

Float fishing with beads or glo bugs imitates salmon eggs drifting through the water. This is the river-specific technique — drift the bead with the current at the depth where fish are holding. Especially effective during peak spawn when egg patterns are visually relevant to the fish.

Spey and Fly Fishing

The Manistee has a strong fly fishing tradition for both salmon and steelhead. Spey rods (two-handed) and traditional fly rods both produce. Intruder patterns, egg flies, and stoneflies are the river standards. Fly anglers tend to concentrate in specific sections of the mid-river rather than Tippy Dam.

What to Bring

• Heavy spinning rod — 8’6″ to 10′ medium-heavy for shore casting; medium for fly
• Spinning reel — Penn Spinfisher VII 6500 or similar
• 14–17 lb mainline with 12–15 lb fluorocarbon leader
• Chest waders — required for most fishing
• Wading staff — current can be strong
• Polarized glasses — essential for spotting fish in clear water
• Net — large rubber-mesh net for landing
• Fishing pliers, line clippers, hook hone
• Layered clothing — Michigan fall mornings can be 35°F
• Fillet knife and cooler for fish you keep

Lodging and Logistics

Manistee (the town at the river mouth) and Wellston (near Tippy Dam) are the two main bases. Wellston is the closer option to Tippy Dam, with several lodges and short-term rentals built specifically for visiting anglers. Manistee offers more lodging variety but is 40 minutes from Tippy.

Reservations should be made 6+ months in advance for the peak September weekends. Lodging fills first; the smaller B&Bs and lodges sell out earliest. Hotel options are more flexible but typically a longer drive to the river.

License and Regulations

Michigan fishing license is required for all anglers 17 and older. Salmon stamp required for keeping salmon. Special regulations apply on the river — current bag and size limits should be checked at the time of your trip. Snagging is illegal in Michigan; all fish must be fair-hooked. Wardens enforce strictly in the Tippy Dam area during peak season.

Frequently Asked Questions

When is the Manistee River salmon run?

Mid-August through late October. Peak king salmon fishing is the second week of September through the first week of October. Coho and steelhead extend the fishery into November and through the winter steelhead season.

Do I need a boat to fish the Manistee?

No — extensive shore access from Manistee to Tippy Dam means you can fish productively without a boat. That said, a boat opens up much more water (especially in the mid-river drift sections) and dramatically increases your fishing options.

Is Tippy Dam crowded during the salmon run?

Yes — peak weekends see hundreds of anglers fishing the dam pool simultaneously. The atmosphere is part combat fishing, part festival. Weekdays are noticeably less crowded. The lower river sections offer more solitude even during peak.

What’s the best technique for Manistee kings?

From a boat: drift fishing wrapped Kwikfish K15 or Yakima Mag Lip 3.5 plugs. From shore: casting Mepps Aglia spinners or float fishing beads and glo bugs through holding water.

Are Manistee kings as big as Lake Michigan trolling kings?

Slightly smaller on average. Fish that successfully make it up the river have already burned some weight on the migration. A 20–25 lb king is excellent for the river; the 30+ lb trophies are more often caught from the lake during pre-spawn staging.

Can I fly fish the Manistee for salmon?

Yes — there’s a strong fly fishing tradition for both salmon and steelhead. Two-handed spey rods are particularly popular. Intruder patterns, egg flies, and large streamers produce. The mid-river sections (downstream of Tippy Dam, upstream of Manistee Lake) offer the best fly water.

Lake Michigan is one of the great inland fisheries in North America. From the spring brown trout bite along Wisconsin’s shore to the August king salmon staging off Manistee, every month offers something — if you know what to target and how to find it. The species shift with the water temperature, the depths shift with the thermocline, and the right month for your trip depends entirely on what you want to catch.

This calendar pulls together the temperature patterns, target species, and trip types for every month of the year on Lake Michigan. Use it alongside the SST charts to time your trip — and the fleet tracker to see where charter boats are actually finding fish in real time.

At a Glance: Lake Michigan Fishing Calendar

Winter: January through March

Water temperature: 32–38°F

Winter is lake trout time. Ice forms on the bays — Green Bay, Grand Traverse Bay, and several smaller embayments freeze most years. The open lake doesn’t typically freeze, but the cold surface temperatures and absence of warmer water mean lake trout can be found at almost any depth. By March, brown trout start moving toward shore in anticipation of the spring shallow-water feed.

What’s biting:

• Lake Trout — The marquee winter species. Ice fishing on the bays produces fish from 20 to 200 feet down depending on bait location. Vertical jigging with tube jigs and rattle spoons is the standard.
• Yellow Perch — Strong ice fishing target on the bays. Green Bay perch fishing in particular is legendary.
• Brown Trout (March) — Begin showing in pier areas and harbor mouths as water hits the high 30s. Pier anglers casting small spoons can find fish.
• Steelhead — Winter steelhead are in the tributaries. Drift fishing with bead rigs and yarn produces during stable winter weather.

SST tip: In late winter and early spring, watch for warming pockets along the shoreline — even a 2°F bump pulls bait and brings predators in.

Spring: April and May

Water temperature: 38–55°F

Spring is the most enjoyable Lake Michigan fishing of the year for many anglers. The water column is essentially uniform — no thermocline yet — and the fish are accessible at shallow depths. You don’t need 200 feet of copper line or a $1500 electric downrigger. You need planer boards, a stickbait, and a small boat or pier.

What’s biting:

• Brown Trout — Peak season. Browns push into shallow water — sometimes 5–15 feet deep — to feed on smelt and emerald shiners. Planer boards with small spoons and stickbaits along the Wisconsin shore produce excellent catches. April is the prime brown trout month on Lake Michigan.
• Coho Salmon — The post-ice-out coho burst is one of the most underrated fisheries on the lake. Coho push shallow to feed aggressively. Planer boards with small spoons and crankbaits in 5–25 feet of water produce. The fish are smaller (3–6 lbs typically) but plentiful and willing.
• King Salmon (May) — First kings start showing as surface temps climb past 50°F. They’re scattered but increasing throughout the month. Anglers with planer boards and shallower downrigger setups (15–35 feet) start catching kings alongside browns and coho.
• Lake Trout — Still in the prime band throughout spring. Accessible at 20–60 foot depths. Trolling with cowbells and spoons in 30–50 feet of water produces.

SST tip: Spring is all about temperature breaks. As different parts of the lake warm at different rates, sharp boundaries form and concentrate bait. The east shore typically warms faster than the west. Watch the SST charts for differential warming.

Early Summer: June

Water temperature: 55–65°F

The transition month. The thermocline starts forming as surface temperatures climb past 60°F. By mid-June, downrigger fishing becomes the dominant technique on the open lake. The salmon are pushing deeper but still accessible without extreme setups. Anglers who target this month can have salmon-quality fishing without the August crowds.

What’s biting:

• King Salmon — Building toward peak. Kings push to thermocline depth, typically 30–60 feet down. The numbers improve weekly as the season develops.
• Coho Salmon — Strong throughout June. Coho hold in the upper thermocline at 20–40 feet, often above the kings. Mixed-species spreads work well.
• Steelhead — Open-water summer steelhead become a real target. They follow the same thermocline pattern as coho, often in 50–80 feet of water.
• Lake Trout — Pushing deeper as surface warms. By late June, lakers are 60–120 feet down and require downrigger or copper line setups.

SST tip: Watch for the first formation of consistent thermocline patterns in the SST data. Areas where surface temps differ sharply over short distances mark thermocline upwellings — fish concentrations.

Peak Summer: July and August

Water temperature: 65–74°F

The headline season. Surface temperatures are at maximum, the thermocline is fully developed, and the fish are at depth. Most charter bookings happen in this window because the king salmon fishing peaks. August in particular sees the pre-spawn staging of kings near tributary mouths — the heaviest fish of the year.

What’s biting:

• King Salmon (Peak) — At 60–120 feet down depending on thermocline depth and bait location. Big spreads with downriggers, dipsy divers, copper line, and lead core all produce. August is when 30+ lb fish become realistic possibilities. Fish are staging for the fall spawn run.
• Coho Salmon — Holding above the kings at 40–70 feet. Smaller spoons and brighter colors. Coho stay aggressive throughout the peak summer period.
• Steelhead — Open-water steelhead through August. Often suspended at 50–80 feet over deep water, far from shore. Excellent fight on appropriate tackle.
• Lake Trout — Deep, at 120–180 feet. Copper line with cowbells and meat rigs, or downriggers with heavy spoons. Slow trolling 1.5–2.0 mph.

SST tip: Surface temp matters less in peak summer than thermocline depth. Use the SST charts to identify where bait is concentrated (chlorophyll-rich areas at the right surface temp), then check downrigger depths to find the prime temperature band at depth.

Pre-Spawn: Late August through September

Water temperature: 62–72°F

This is the moment many Lake Michigan anglers wait all year for. As kings begin their pre-spawn staging, they push toward the major tributary mouths — Manistee, Pere Marquette, Big Manistee, Platte, St. Joseph. The fish are heavy, aggressive, and accessible at shallower depths than peak summer. Charters book heavily; recreational anglers run early-morning trips for the staging fish.

What’s biting:

• King Salmon (Trophy Stage) — Pre-spawn kings staging in 40–80 feet of water near tributary mouths. Heaviest fish of the year. River mouth fishing produces excellent results.
• Coho Salmon — Building toward their fall run. Coho push into harbors and river mouths in September. Pier and shore fishing becomes productive.
• Steelhead — Beginning to push toward rivers but still scattered through the open lake.
• Brown Trout — Return to shallower water as surface temps drop. Pier fishing improves.

SST tip: Watch for the surface temperature drop. When surface temps begin retreating from peak (mid-August through September), kings push shallower because the right temperature band shifts upward in the water column.

Fall Run: October

Water temperature: 52–62°F

The shore-based angler’s window. The pelagic fishing season winds down as the open-water fish push into rivers or move to deep water. But the rivers light up — coho, steelhead, and brown trout all run in October. The Manistee, Pere Marquette, Betsie, and St. Joseph rivers produce. Pier fishing in the harbors picks up too as remaining fish stage before entering the tributaries.

What’s biting:

• Coho Salmon (Fall Run Peak) — Late September into early October. Rivers and pier fishing produce double-digit days during the peak. River fishing techniques apply.
• Steelhead — Begin pushing into tributaries. October steelhead can be excellent in the rivers, with hot patches following heavy rains.
• Brown Trout — Push shallow as surface cools. Pier and shore fishing produces.
• Lake Trout — Beginning to spawn over shallow rocky structure in late October. Accessible at 20–50 foot depths near reefs.

SST tip: Watch for the surface temps reaching back into the 50s. That’s the signal that lake trout will move shallow for the spawn and that nearshore brown trout fishing will improve.

Late Fall and Early Winter: November and December

Water temperature: 35–52°F

The transition out of the active season. The salmon run ends. Lake trout spawning concludes. Surface temperatures drop quickly. Some anglers continue trolling for late lake trout and steelhead in stable weather windows; most shift to river fishing for steelhead or wait for ice.

What’s biting:

• Brown Trout — Pier fishing remains productive into November in many areas. Stable weather windows produce.
• Lake Trout — Post-spawn fish accessible at moderate depths. Steady fishing through November.
• Steelhead — River fishing peaks for fall-run fish. Many of the major Michigan and Wisconsin tributaries produce.
• Whitefish — Late fall whitefish fishing on the bays. Niche but productive for anglers who know the spots.

Best Months for Each Species

Top Lake Michigan Fishing Ports

The major ports each have their own seasonal specialties:

• Manistee, MI — The biggest charter port. Excellent August salmon fishing and direct access to the Manistee River for fall runs.
• Ludington, MI — Strong charter fleet, excellent summer king fishing.
• Frankfort, MI — Smaller charter base but legendary water access to deep water just offshore.
• Sheboygan, WI — Wisconsin’s premier port. Strong June–August salmon, fall coho run.
• Milwaukee, WI — Easy airport access, strong charter fleet.
• Waukegan, IL — Day-trip access from Chicago.
• St. Joseph, MI — Southern lake fishing, strong fall river run.

How to Use Ocean and Lake Data to Plan Your Trip

1. Identify the season — Use this calendar to narrow down what you want to target by month.
2. Check the SST charts — See current surface temperatures. Are they running ahead or behind the average for the date? That shifts the species timing earlier or later.
3. Look for temperature structure — Breaks, upwelling, warm/cold edges. Our guides on reading SST charts and finding temperature breaks show what to look for.
4. Cross-reference the chlorophyll map — Productive water indicates bait concentrations.
5. Watch the fleet tracker — Real-time intelligence on where charter boats are running.
6. Check the AI predictions — Daily forecasts that synthesize all of the above.

Lake trout — lakers — are the deep, cold-water specialists of the Great Lakes. While kings and coho push shallow when conditions allow, lakers stay committed to the cold. They’re the species you can target almost year-round because their temperature window stays accessible somewhere in the water column every month. In winter when the salmon are gone, lake trout are at their peak. In summer when the salmon are 100 feet down, lakers are 100 feet below that.

Lake trout are also the native species of the Great Lakes — the only one of the major salmonids that’s truly indigenous rather than stocked from Pacific or Atlantic origins. That matters because the populations are mature, structured, and predictable. If you understand the temperature patterns, you can find lakers in any month of the year. This guide pulls together the temperature ranges and depth patterns from DNR data across all five lakes.

The Quick Answer

Lake trout prefer water temperatures between 45°F and 52°F (7–11°C). The sweet spot for active feeding is 48–50°F. They tolerate water from about 40°F to 55°F and can be caught throughout that range with the right techniques. Above 55°F, lakers move deeper or to upwelling zones; they will not stay in warmer water.

The key difference from salmon: lakers are always cold-water fish. There’s no period when surface temperatures bring them up. In winter and early spring they may feed at 25 feet because the whole water column is in their range. By summer they’re 100–200 feet down because that’s the only place the cold water exists. Find the cold water, find the lakers.

Temperature Range Breakdown

How Lake Trout Differ from Salmon

Understanding what makes lakers different shapes how you target them:

Slower metabolism. Lake trout grow slowly, fight more steadily than aerobically, and feed deliberately. They’re not the explosive ambush predators that kings are. They cruise and pick off prey. This means slower trolling speeds (1.5–2.2 mph) and presentations that emphasize action over speed.

Bottom-oriented. While salmon suspend in the thermocline, lake trout relate to structure on the bottom — humps, dropoffs, rock piles, and sunken islands. Even when they’re suspended, they’re usually within 20–30 feet of bottom rather than mid-column.

Year-round availability. Lakers are the most consistent Great Lakes target. Ice fishing for lakers is excellent on Lakes Superior, Huron, and parts of Michigan and Ontario. Summer trolling produces them in the depths. Spring and fall offer accessible shallower fishing.

Different bait base. Lakers feed on alewives like salmon do, but also eat sculpins, smelt, lake whitefish, and other lake-bottom species. In some lakes (notably Superior), they’re more reliant on native forage than introduced alewives.

Seasonal Patterns

Winter (December–March): The Ice Fishery

Lake trout become the marquee species. Surface temps are at or near freezing — well within their tolerance — and lakers can be found at almost any depth. On Superior, lakers are caught through the ice in water from 20 to 200 feet deep, depending on bait location. Vertical jigging with tube jigs, spoons, and rattle baits produces. Set lines with shiners or smelt account for many of the bigger fish. See the ice fishing lake trout section for techniques.

Spring Post-Ice-Out (April–May): Shallow Window

This is when lakers are most accessible to boat anglers. Surface temps in the high 30s and low 40s mean the entire water column is in lake trout range. Fish push into 20–60 foot depths to feed on smelt and alewives staging in shallow water. Trolling stickbaits, smaller spoons, and cowbells produces. Casting from shore at river mouths and along rocky shorelines occasionally works. This 4–6 week window before the thermocline forms is the most enjoyable laker fishing of the year — no deep gear required.

Early Summer (June): Going Deep

As surface temps push past 55°F, lakers leave the shallows. They follow the cold water down to whatever depth keeps them in their range. By mid-June on Lake Michigan, lakers are typically 80–150 feet down. Downrigger trolling becomes the primary technique. Lakers stay below the salmon throughout summer.

Peak Summer (July–August): Deep Trolling

Lakers hold at 100–200 feet down depending on the lake and structure. Lake Superior’s deep cold water means lakers can be at relatively shallow depths even in summer — sometimes 60–80 feet — while Lake Michigan and southern Lake Huron drive them down to 120–180 feet. Downriggers with copper or lead core lines, trolled spoons or cowbells with attractors, and slow speeds (1.5–2.0 mph) produce. Vertical jigging over structure with heavy spoons is the alternative approach.

Fall (September–November): Coming Back Up

As surface temperatures drop back through the 50s, lakers push shallower. By late September on most lakes, they’re back at 60–100 feet. October and November produce excellent laker fishing as the water column re-equilibrates. Lakers also spawn in the fall — over shallow rocky reefs in late October through November — making them temporarily accessible in 20–50 foot water.

Lake-Specific Patterns

Lake Superior — The cold water king. Surface temps rarely exceed 60°F even in mid-summer. Lakers stay relatively shallow year-round compared to other Great Lakes — 60–100 feet is typical summer depth rather than 150+. Superior produces the biggest lakers, with fish over 30 lbs not uncommon.

Lake Michigan — Deeper holding pattern. Summer lakers at 120–180 feet. Strong lakers fishery on the central basin and along the eastern shore near the deep water of the Manistee–Frankfort corridor.

Lake Huron — Mixed pattern depending on basin. North Channel and Georgian Bay produce excellent lakers, often shallower than main lake. Saginaw Bay is too warm in summer for the open water; lakers move to deep main-lake basins.

Lake Ontario — Deep cold water available year-round. Lakers stay relatively accessible. Trolling near the eastern basin and the deep water off Olcott produces.

Lake Erie — Limited laker presence. Erie is too warm and too shallow for a strong lake trout population. Not a primary lake trout destination.

Temperature vs Other Factors

Structure matters more than for salmon. Lakers relate to bottom features in ways kings and coho don’t. Humps, dropoffs, and rock piles concentrate fish even when temperature alone wouldn’t predict them there. Lakers will use structure that puts them at the right temperature.

Bait position. Lakers feed on whatever’s available — smelt, alewives, sculpins, ciscoes (in Superior), whitefish. Find the bait at the right temperature and you find the lakers.

Oxygen levels. Below the thermocline, dissolved oxygen can drop in some basins (particularly Lake Erie’s central basin in late summer). Lakers won’t sit in low-oxygen water even if the temperature is right. This rarely matters in Lakes Superior, Huron, or Michigan but is relevant in Erie’s deeper holes.

Light penetration. Lakers feed in low light better than bright. The deeper they hold in summer, the less light becomes a factor. In shallow spring water, dawn and dusk produce better than midday.

How to Use SST Charts for Lake Trout

Surface temperature charts work differently for lakers than for salmon because lakers spend most of the year well below the surface temp band.

1. In spring and fall — open the SST charts and look for cooler pockets, particularly along shaded shorelines or where upwelling is happening. Lakers gravitate to those areas when temps are borderline.
2. In summer — surface temp matters mostly to confirm the thermocline has set up. Once it has, focus on bathymetric maps showing depths where the cold water sits.
3. Look for structure on charts — humps, dropoffs, and points in the depth range where the prime temperature exists. The intersection of structure and cold water is laker country.
4. Check the chlorophyll map for bait-holding water adjacent to lake trout structure.
5. Check the fleet tracker for charter activity, particularly mid-day when laker-focused boats are working deep water.

Frequently Asked Questions

What’s the best temperature for lake trout?

Lake trout feed most actively at 48–50°F, with the prime band running 45–52°F. They tolerate 40–55°F and can be caught throughout that range. Above 55°F they move deeper or out of an area entirely.

How deep are lake trout in summer?

Depends on the lake. Lake Superior lakers may be 60–100 feet down in summer. Lake Michigan lakers typically hold at 120–180 feet. Lake Huron varies by basin — 80–150 feet is common. The key principle: wherever the cold water is, that’s where the lakers are.

Can I catch lake trout from shore?

In spring (April–May) before the thermocline forms, yes — particularly along rocky shorelines where cold deep water comes close to shore. Fall spawn (late October–November) brings lakers into very shallow rocky areas. Summer shore-based lake trout fishing is essentially impossible except in Lake Superior where cold water reaches the surface.

What’s the best technique for lake trout?

Depends on season. Spring: trolling stickbaits and cowbells in shallow water. Summer: downrigger trolling with heavy spoons, copper line, or vertical jigging over structure with tube jigs. Fall: similar to spring as fish push shallower. Winter ice fishing: vertical jigging with tube jigs and spoons, plus tip-ups with shiners.

Are lake trout good to eat?

Yes, though they’re an acquired taste compared to salmon. Lakers have higher fat content and a stronger flavor. They smoke exceptionally well — many lake trout anglers preserve the bulk of their catch this way. Fresh fillets are best when cold-smoked or grilled with strong seasonings.

What’s the difference between lake trout and king salmon?

Lake trout are native to the Great Lakes; kings were introduced. Lakers prefer colder water (45–52°F vs 50–58°F for kings), live longer, grow slower, and survive multiple spawning cycles. Kings die after spawning. Lakers fight steadier and more deliberately; kings make explosive runs. Lakers are bottom-oriented; kings suspend in the thermocline.

King salmon — Chinook — are the most temperature-driven fish in the Great Lakes. They don’t just prefer cold water; they require it. A 4°F shift can mean the difference between marking fish stacked at 80 feet and an empty sonar screen. Every Great Lakes charter captain I’ve spoken with says the same thing: find the right temperature band, and you find the fish.

I haven’t trolled Lake Michigan myself — my fishing background is SoCal saltwater and freshwater — but the temperature dynamics work the same way they do for Pacific salmon. The data is consistent across DNR reports, captain logs, and decades of charter fleet history. This guide pulls all of it together: the temperature ranges that produce, the seasonal patterns that move kings through the water column, and how to use SST charts to find them.

The Quick Answer

King salmon prefer water temperatures between 50°F and 58°F (10–14°C). The sweet spot for Great Lakes trolling is 52–56°F. Below 48°F, kings become sluggish and feed less aggressively. Above 60°F, they push deeper or move to find cooler water — often dropping below the thermocline where bait isn’t present.

The single most important thing to understand: kings follow the thermocline, not the surface. By July and August, surface temperatures on Lake Michigan can hit 70°F+ while kings are stacked at 60–120 feet down in 52°F water. Your downrigger depth matters far more than what the surface temperature shows.

Temperature Range Breakdown

The narrower window than other salmonids — a 6-degree prime band compared to 8–10 degrees for coho — is why king salmon trolling is so tied to electronics. You need to know exactly where the right temperature is, then put your spread right in it.

Understanding the Thermocline

The thermocline is the layer where water temperature drops rapidly with depth. In the Great Lakes, it forms in late spring as surface water warms while deep water stays cold. By midsummer, a typical Lake Michigan profile looks like this:

• Surface to 40 ft: 65–72°F (warm, mostly empty for kings)
• 40–60 ft: Rapid drop through the thermocline (70°F → 50°F in 20 feet)
• 60–120 ft: 48–55°F (the king zone)
• Below 120 ft: 42–48°F (too cold, lake trout territory)

Kings stage along the thermocline because that’s where bait pushes against the cold barrier. Alewives — the primary forage — concentrate where warm and cold water meet. Your trolling spread needs to be at thermocline depth, not 20 feet above or below it.

A temperature/speed probe like the Fish Hawk gives you the exact thermocline depth at downrigger depth. Without one, you’re estimating from surface temp and depth charts. Most charter captains run probes; many serious recreational anglers do too.

Seasonal Patterns

Spring (April–May): Shallow and Scattered

Surface temperatures are still in the 40s. No thermocline has formed yet — the water column is roughly uniform from top to bottom. Kings are scattered, often shallow, mixed with brown trout and coho. Target water in the 45–52°F range, typically along temperature breaks where slightly warmer water concentrates bait. Downriggers are optional this time of year; planer boards and lead core lines do the work. Watch for temp breaks of 2–3°F — even a small variation pulls bait and predators.

Early Summer (June): Thermocline Forms

As surface temps climb through the 50s into the 60s, the thermocline begins to set up. Kings push deeper, following the 52–56°F band downward through the water column. Mid-June is when downrigger fishing becomes the dominant technique. The kings are usually 30–60 feet down at this point, holding right at thermocline depth. Trolling speeds pick up to 2.4–2.6 mph as the fish become more active.

Peak Summer (July–August): Deep and Stacked

The thermocline has fully set up by July. Kings are stacked at 60–120 feet down, holding tight to the thermocline edge. Surface temps mean nothing now — what matters is downrigger depth and the temperature at that depth. Anglers with temp probes drop riggers right to the 52–56°F band and put their flashers and spoons in the zone. Without a probe, depth recommendations from charter reports become essential. This is the bluewater grind: long days, big spreads, fish counted in pounds not numbers.

Pre-Spawn Stage (Late August–Early September): Approaching Shore

This is the moment Great Lakes anglers wait all year for. As kings start their pre-spawn movement toward the rivers, they push into shallower water — often 40–80 feet — while still seeking the 52–56°F band. They stage near the major tributary mouths (Manistee, Salmon River, Niagara). Surface temps are still warm but the kings are heavier, bigger, and more aggressive. The fish are full-weight before the spawn and feeding hard.

Fall Run (September–October): Shallow and Aggressive

Kings push into the river mouths and tributaries. Water temps in the rivers and harbors run cooler than the lake by this point, often 55–62°F. Pier fishing and river fishing dominate. The fish are no longer feeding the same way — they’re focused on spawning — but they still hit out of aggression. This is when shore-based anglers get their shot.

Winter (November–March): Lake Trout Take Over

King salmon season is effectively done. The surviving fish are in the rivers (post-spawn) or have moved to deep, stable water. Anglers shift to lake trout, which thrive in the 45–50°F water that’s now everywhere. See the lake trout temperature guide for the winter fishery.

Temperature vs Other Factors

Bait availability — Temperature gets you in the right zone, but bait makes the fish bite. Alewives concentrate in specific depth bands tied to temperature and oxygen. When kings, alewives, and the right temperature line up at the same depth, that’s where the fishing happens. A chlorophyll map shows where the productive water is — chlorophyll-rich water feeds alewives, alewives feed kings.

Light and time of day — Kings feed best in low light. Pre-dawn through about 9 AM, then again from 6 PM to dusk. Midday in bright sun, fish push deeper than the temperature alone would suggest. Add 10–20 feet to your normal trolling depth at high noon.

Currents and upwelling — Great Lakes upwelling events push cold water to the surface near shore. After a strong northeast wind on Lake Michigan, surface temps near the east shore can drop 10°F overnight as 50°F water gets pulled up from depth. Kings follow these temperature shifts aggressively — a shore-side upwelling concentrates fish in places they wouldn’t normally be.

Moon and barometric pressure — Pre-frontal conditions (falling barometer) trigger feeding. Stable high pressure for 3+ days produces tough fishing. Major and minor moon periods produce noticeable bumps in catch rates on charter logs.

How to Use SST Charts to Find Kings

Surface temperature charts on the Great Lakes work differently than they do in saltwater. The surface temp itself doesn’t tell you where the kings are — what it tells you is where the thermocline likely sits and where temperature breaks are forming.

1. Open the SST charts and look at your target lake. Note the general temperature range.
2. Identify temperature breaks — places where surface temp changes 3°F or more over a short distance. These almost always indicate underwater structure or current convergence that concentrates bait.
3. Cross-reference with depth contours. Temperature breaks over structure (sharp dropoffs, points, humps in 80–150 feet) are king salmon highways.
4. Check the chlorophyll map for productive (greenish-yellow) water adjacent to the temp break. Bait + temp break + structure = the magic intersection.
5. Plan your trolling pass to run along the temperature break, not across it. Kings hold to one side or the other depending on which side the bait is on.
6. Check the fleet tracker to see where charter boats are working. Charter captains find fish first — their AIS tracks are a free fishing report.

Water Temperature Guides for Other Species

Once you know how to use temperature for kings, the same logic applies across species — though each one has its own preferred band:

• Best Water Temp for Coho Salmon — 54–60°F, slightly warmer than kings
• Best Water Temp for Atlantic Salmon — 50–58°F, similar to kings
• Best Water Temp for Lake Trout — 45–52°F, deeper and colder
• Best Water Temp for Bluefin Tuna — saltwater comparison, similar magic-number approach
• Best Water Temp for Yellowtail — Pacific saltwater equivalent

Frequently Asked Questions

What temperature do king salmon prefer in the Great Lakes?

King salmon (Chinook) feed most actively at 50–58°F, with 52–56°F being the prime window. They will tolerate temperatures from about 45°F to 62°F but become sluggish below 48°F and push deeper above 60°F. The narrow prime band is why precise temperature targeting matters so much for kings.

How deep do I need to fish for kings in summer?

By July and August on Lake Michigan, kings are typically 60–120 feet down — wherever the thermocline puts the 52–56°F water. A temperature/speed probe at downrigger depth is the most reliable way to find the exact zone. Without one, start at 60 feet and work down until your spread is in the band that’s producing.

Can I catch king salmon without downriggers?

In spring (April–May) yes, with planer boards and lead core. By June the kings are deep enough that downriggers become essential for boat anglers. From shore, pier and river fishing during the August–October pre-spawn run produces fish without any specialized depth gear.

What’s the difference between king and coho temperature preferences?

Coho prefer slightly warmer water (54–60°F) and are more tolerant of variation. Kings are tighter to the 52–56°F band and push deeper faster when surface temps warm. In mixed-species water, coho will often be 20–40 feet shallower than kings holding at the same time.

How does upwelling affect king salmon fishing?

Upwelling events push cold deep water to the surface near shore, usually after sustained winds blow surface water offshore. Kings follow these temperature changes aggressively, sometimes appearing in shallow water within 24 hours of an upwelling event. Watch surface temperature drops of 10°F or more along a shoreline as a tip-off.

What’s the best time of year to target trophy kings?

Late August through mid-September is peak for trophy kings. Pre-spawn fish are at maximum weight after feeding all summer, and they stage near tributary mouths in accessible depths. Boat trolling near the river mouths and pier fishing both produce trophies in this window.

Tight lines!

Coho salmon — silvers — are the more forgiving cousin of the Chinook. They feed across a wider temperature band, push shallower in summer, and stay aggressive through more variable conditions. For anglers learning Great Lakes trolling, coho are the species that builds confidence. The temperature window is more generous, the strikes more enthusiastic, and the fish are willing to chase a lure faster and farther than kings.

That said, “more forgiving” isn’t the same as “doesn’t care.” Coho still concentrate in specific temperature bands tied to bait, structure, and season. The anglers who consistently put coho in the box are the ones who understand those bands and use them to set their trolling depth, speed, and spread. This guide pulls together the temperature patterns from DNR data and Great Lakes charter reports so you can do the same.

The Quick Answer

Coho salmon prefer water temperatures between 54°F and 60°F (12–16°C). The sweet spot for Great Lakes trolling is 55–58°F. Coho will feed actively from about 50°F up to 62°F, making them more tolerant than kings, but they push to the deeper edge of that band when surface temps climb. Below 48°F, coho slow down dramatically — though early spring fish are an exception, often feeding hard right after ice-out at 42–48°F.

Compared to kings, coho run 2–4°F warmer in their preferred zone. That means in summer, coho typically hold 20–40 feet shallower than the kings on the same water — often in the upper portion of the thermocline rather than below it.

Temperature Range Breakdown

The wider prime band — 6 degrees vs the kings’ tight 4–6 — gives coho anglers more flexibility. When kings are tough because the thermocline shifted overnight, coho often stay in the game.

Why Coho Are Easier Than Kings

A few practical differences worth knowing if you’re transitioning from king-focused fishing:

Wider temperature tolerance. Coho can sit in 56°F water all day; kings get restless and move. This means you don’t have to chase tiny temperature shifts the way kings demand.

Higher in the water column. Even in peak summer, coho often hold at 30–60 feet while kings are 80–120. Shorter downrigger setups work. Lead core lines and dipsy divers reach them effectively.

More aggressive strikes. Coho hit lures with reckless commitment. Kings often follow and refuse; coho commit. This means hook-up rates are higher and missed strikes are less common.

Faster trolling speeds work. Coho will run down a 3.0 mph spoon all day. Kings prefer 2.4–2.6 mph. If you’re searching unfamiliar water, troll faster — you’ll cover more ground and the coho will still hit.

Seasonal Patterns

Early Spring (April): The Shallow Burst

Post-ice-out is the underrated coho window. Surface temps are still in the low to mid 40s — colder than the official prime band — but coho push shallow to feed aggressively after winter. They’re often inside the 50-foot contour, sometimes within casting distance of pier anglers. Planer boards with small spoons and crankbaits in 5–25 feet of water produce. The fish are smaller (3–6 lbs typically) but plentiful and willing.

Late Spring (May): Transition

Surface temps climb into the high 40s and 50s. Coho start spreading out and pushing slightly deeper as the warmer surface water layer develops. Brown trout fishing peaks during this period — coho mix in with the browns on the shallow reefs. This is when planer board fishing transitions to early downrigger setups, usually 15–35 feet down.

Early Summer (June): Thermocline Begins

The thermocline starts to form. Coho push to its upper edge — typically 30–50 feet down where surface water meets the colder layer. Downriggers become the dominant technique. Speeds bump up to 2.5–2.8 mph. The fish are 6–9 lbs by this point and feeding hard on alewives that concentrate at the thermocline boundary.

Peak Summer (July–August): Above the Kings

The thermocline is fully developed. Surface temps are 65–72°F. Coho hold in the 56–60°F band, which puts them at 40–70 feet down — above the kings holding deeper in 52–56°F water. Mixed-species trolling spreads work well in this period: shallower riggers and dipsies for coho, deeper ones for kings. Charter boats often run 6–8 rod spreads to cover both depth ranges.

Fall Run (September–October): The Big Show

This is when coho fishing peaks. As surface temps drop back into the 50s and 60s, coho push into shore and stage near tributary mouths for their spawning run. Pier and river fishing produces double-digit fish counts on good days. The coho run is shorter and more concentrated than the king run, but the fish are often more accessible to shore-based anglers. The Salmon River in New York, the Manistee in Michigan, and the Sheboygan in Wisconsin are classic fall coho destinations.

Winter (November–March): Done

Coho season ends with the spawn. The surviving fish die after spawning (Pacific salmonid life cycle), and adult coho aren’t a winter target. Next year’s class is finning the rivers as smolts.

Temperature vs Other Factors

Bait location — Coho follow alewives more aggressively than kings do. If alewives are at 30 feet because of where the chlorophyll-rich water sits, coho will be there even if 30 feet isn’t strictly in the prime temperature band. The chlorophyll map often predicts coho location better than the SST chart alone.

Light penetration — Coho feed in brighter light than kings. Midday coho fishing produces better than midday king fishing. That said, dawn and dusk are still the best windows.

Water clarity — Coho prefer clearer water than kings. After heavy rain that pushes muddy water out of tributaries, coho often move offshore until clarity returns. Kings tolerate dirty water better.

Wind direction — A west or southwest wind on Lake Michigan piles bait against the east shore and concentrates coho into manageable areas. East winds push bait offshore and scatter coho into harder-to-find pods.

How to Use SST Charts for Coho

1. Check the SST charts for surface temperatures in your target area. Coho often sit very close to the surface temp band when conditions are right.
2. Look for moderate temperature breaks — 2–4°F changes over short distances. Coho aren’t as tied to sharp breaks as kings; they spread along gentler temperature gradients.
3. Cross-reference the chlorophyll map. Greenish productive water within the 54–60°F band is where the alewives are, and where the coho will be.
4. Plan to fish shallower than for kings. If kings are at 80 feet, coho are typically at 40–60. Plan your trolling spread accordingly.
5. Check the fleet tracker for charter activity. Most Great Lakes charters target whatever’s biting; if boats are running, the fish are there.

Frequently Asked Questions

What temperature do coho salmon prefer?

Coho prefer 54–60°F, with 55–58°F being the prime band. They tolerate temperatures from about 48°F to 64°F and feed across that range, but the highest catch rates come in the prime window. Spring coho will feed in colder water (42–48°F) but only briefly during the post-ice-out feeding burst.

Are coho easier to catch than king salmon?

Generally yes. Coho feed across a wider temperature band, hold shallower in the water column, hit lures more aggressively, and tolerate faster trolling speeds. For anglers new to Great Lakes trolling, coho are the more forgiving species to learn on. Kings demand more precision.

How deep are coho in summer?

Typically 30–60 feet down by July, depending on where the thermocline sits and where bait is concentrated. This is shallower than kings, which usually hold below 60 feet by the same point in the season. Coho stay in the upper portion of the thermocline rather than below it.

When is the fall coho run?

The fall run peaks in late September and early October on most Great Lakes tributaries. Coho stage near river mouths in the harbors and piers before pushing into the rivers themselves. The run is shorter and more concentrated than the king run — typically a 2–3 week peak window — but produces excellent shore-based fishing.

What’s the difference between coho and king salmon temperature preferences?

Coho run 2–4°F warmer than kings in their preferred band. In mixed-species water, coho will be 20–40 feet shallower than kings holding at the same time. Coho also tolerate more temperature variability — a 4°F shift that scatters kings may not move coho at all.

Can I catch coho without a boat?

Yes — especially in spring and during the fall run. Spring coho push shallow enough that pier and surfcasting produces. The fall run brings coho into the rivers and harbors where shore anglers, pier fishermen, and waders all have access. Mid-summer coho are harder to reach without a boat.

Tight lines!

Atlantic salmon are the underrated member of the Great Lakes salmon family. They don’t get the attention kings and coho do — the Pacific salmon program in the Great Lakes started in the 1960s and Atlantics arrived later — but the fishery has grown into something special, particularly on Lake Huron and the St. Marys River system. Anglers who target Atlantics talk about them like a different kind of fish: harder fighting pound-for-pound than Pacific salmon, more acrobatic, and more selective about water temperature and bait.

The temperature dynamics for Atlantics overlap with kings but with key differences. They hold in similar water but use it differently — staging in current, suspending in slightly shallower bands, and reacting more strongly to barometric shifts. This guide pulls together the temperature patterns from Michigan DNR data, Ontario fishery reports, and Atlantic-focused charter logs.

The Quick Answer

Atlantic salmon prefer water temperatures between 50°F and 58°F (10–14°C). The sweet spot for Great Lakes Atlantics is 54–58°F. They will feed actively from about 48°F up to 62°F, with optimal aggression in the upper part of the prime band. Below 46°F they slow down significantly. Above 64°F they push deep or move to seek cooler water.

While the headline range looks similar to king salmon, Atlantics actually trend slightly warmer than kings within that range — closer to coho preferences. The 54–58°F window is the sweet spot rather than the cooler 50–54°F kings often prefer.

Temperature Range Breakdown

What Makes Atlantics Different

A few traits set Atlantics apart from Pacific salmon and shape how temperature affects them:

Multi-spawn life cycle. Unlike Pacific salmon, Atlantics don’t all die after spawning. Many survive and return to spawn multiple times. This means the population includes fish of varied sizes and ages, often holding at different depths in the same water.

Current preference. Atlantics are drawn to flowing water and current edges far more than kings or coho. This is why the St. Marys River — connecting Lake Huron to Lake Superior — is the premier Great Lakes Atlantic fishery. They stage in current seams and feed on bait being pushed past them.

Selective feeding. Atlantics will refuse lures that coho would hammer. Color, action, and trolling speed matter more for Atlantics than for the other species. Spoons that produce one day may be ignored the next.

Acrobatic fighter. When hooked, Atlantics jump repeatedly. A 12-pound Atlantic puts on more visual display than a 25-pound king. Loose drag and a long rod with give matter — they pull treble hooks easier than Pacific salmon.

Seasonal Patterns

Spring (April–June): Nearshore and Aggressive

Post-ice-out is prime time on Lake Huron and the St. Marys system. Atlantics push into shallow water — 10–30 feet — to feed on smelt and emerald shiners. Surface temperatures in the 40s and low 50s find the fish active and willing. Planer board trolling with stickbaits and small spoons in colors like blue/silver, green/silver, and gold produces. This is when shore-based anglers and small-boat operators have their best window before the fish push offshore.

Early Summer (June–July): Thermocline Setup

As surface temps climb into the 60s, the thermocline forms. Atlantics push to the upper part of it — typically 25–55 feet down, holding above the kings. Downriggers come into play but lead core and dipsy divers are still effective because the fish aren’t as deep as kings yet. The St. Marys River fishery transitions: river-mouth and nearshore fishing slows as fish push out to lake water, but the river current itself still holds resident Atlantics that don’t make the same offshore migration.

Peak Summer (July–August): The Deep Push

The thermocline is fully developed. Atlantics hold at 50–90 feet down in the 54–58°F band. Lake Huron’s deep basin produces well during this period, particularly the western shore from Rogers City to Alpena. Atlantics often suspend above structure rather than holding on it — a different pattern from lake trout in the same water. Look for clouds of bait on the sonar with Atlantics above them.

Pre-Spawn (Late August–September): River Bound

Atlantics that spawn move toward tributaries. Unlike Pacific salmon, not every Atlantic spawns every year, and not every fish dies after spawning — but a significant portion of the population stages near tributary mouths in early fall. The St. Marys River fishery is the most accessible, with fish holding in the rapids and current seams. Pier and shore fishing produces in this window.

Fall and Winter (October–March): Mixed Strategy

Post-spawn surviving Atlantics return to the lake. They feed during stable weather windows but become harder to target consistently. Winter ice fishing for Atlantics is a niche but real fishery, particularly on Lake Ontario embayments and parts of Lake Huron near tributary mouths.

Where Atlantic Salmon Fishing Happens

Atlantic salmon distribution in the Great Lakes is much more concentrated than kings or coho. The major fisheries:

Lake Huron — the Atlantic stronghold. Particularly the northern part of the lake from Hammond Bay south to Tawas. Rogers City and Alpena are the popular charter ports. The combination of cold water, current from connecting waterways, and stocked populations makes this the best Atlantic salmon water in the lower 48.

St. Marys River. Connecting Lake Huron to Lake Superior, this fast-flowing river holds resident Atlantics year-round and pulls in lake-run fish during spawning. The rapids section near Sault Ste. Marie is famous water. Fly fishing and pier fishing both produce.

Lake Ontario. The Atlantic salmon restoration program has been working for decades. The fishery is less dense than kings or coho but real, with fish concentrated near the eastern basin and tributaries like the Salmon River, Little Salmon, and Black River.

Lake Michigan. Limited Atlantic salmon presence. Mostly stray fish from other lakes or limited stocking. Not a primary target.

Temperature vs Other Factors

Current and structure — Atlantics relate to current more than other Great Lakes salmonids. Even in open lake water, they often hold along current edges created by underwater structure, river plumes, or wind-driven flow. Temperature gets them in the area; current concentrates them on specific spots.

Bait type — Atlantics in lake water primarily feed on alewives and smelt. In the St. Marys River, emerald shiners and small whitefish are dominant. Match the hatch — fly anglers in particular need to size and color their patterns to local forage.

Barometric pressure — Atlantics are notably sensitive to pressure changes. Falling barometer before a front triggers feeding. Stable high pressure for several days produces tough fishing. This is more pronounced for Atlantics than for kings or coho.

Water clarity — Atlantics prefer clear water. After heavy rain or wind that pushes muddy water out of tributaries, Atlantics move offshore until clarity returns. This is one reason the St. Marys River fishery is reliable — the water there is consistently clear.

How to Use SST Charts for Atlantics

1. Open the SST charts for your target lake — likely Lake Huron or Ontario. Identify areas in the 54–58°F band.
2. Look for current convergences — places where surface water moves in different directions, often indicated by surface debris lines or color changes. These current edges concentrate Atlantic salmon disproportionately.
3. Cross-reference with structure — points, reefs, and dropoffs that interact with current. The intersection of cold water, structure, and current is prime Atlantic water.
4. Check the chlorophyll map for productive bait water in the prime temperature zone.
5. Plan to fish above the thermocline rather than below it. Atlantics typically hold higher in the water column than kings.
6. Check the fleet tracker for charter activity, particularly out of Lake Huron’s Atlantic-focused ports.

Frequently Asked Questions

What’s the best water temperature for Atlantic salmon?

Atlantic salmon feed most actively at 54–58°F. They tolerate temperatures from 46°F to 62°F but the prime band is narrower than coho and trends slightly warmer than kings within the overlap zone.

Where can I catch Atlantic salmon in the Great Lakes?

Lake Huron is the strongest Atlantic salmon fishery, particularly the northern half between Hammond Bay and Tawas. The St. Marys River connecting Huron to Superior holds Atlantics year-round. Lake Ontario has a growing fishery in the eastern basin and tributary mouths.

How are Atlantic salmon different from king and coho?

Atlantics don’t all die after spawning, may spawn multiple times, prefer water with current, are pickier about lure presentation, and are more acrobatic when hooked. They hold higher in the water column than kings and prefer clear water more than coho.

Can I catch Atlantic salmon from shore?

Yes, especially in spring when fish push shallow, and during the fall pre-spawn run when they stage near tributary mouths. The St. Marys River rapids are wadeable in places and produce excellent shore fishing. Pier fishing in Lake Huron’s Atlantic ports also produces during the spring run.

When is the best time to fish for Atlantics?

Spring (April–June) for nearshore, accessible fish. Summer (June–August) for offshore trolling with downriggers. Late August through September for pre-spawn river fish in the St. Marys system.

What lures work best for Atlantic salmon?

Spoons in blue/silver, green/silver, gold, and chartreuse patterns. Smaller stickbaits like Husky Jerks for spring. Cleo and Krocodile spoons for casting. In rivers, flies sized to local bait. Atlantics are pickier than coho or kings — be willing to change colors and sizes more frequently.
