40,172-acre lake near ᐚᐸᓂ ᓵᑲᐦᐃᑲᓂᕽ Morin Lake. The lake tops out around 30 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 40,115 acres, worked by 278.5 miles of shoreline, with 60 islands in the mix. An index of 9.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 76% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 22.5 mi with a 21.8-mi widest point. It sits in Division No. 18. Its nearest charted neighbour, Midway Lake, is 19 mi to the northeast.
When the water first warms, burbot slide up into 9 to 30 ft. There's no big seasonal slide here — summer means 9 to 30 ft, winter 8 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in spring. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft | night & dusk | Deep basin (26 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 9 to 30 ft | night & midday | Deep basin (26 ft) | Heavy jig + cut bait |
| Fall | 9 to 30 ft | night & dusk | Deep basin (26 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 8 to 30 ft | night & dusk | Deep basin (26 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Start shallow in spring: cisco (lake herring) sit in 8 to 30 ft that time of year. They don't go far with the seasons — 9 to 30 ft covers summer, 9 to 30 ft covers winter. The spot to know is Deep basin, a deep basin in about 26 ft of water that rates prime for cisco (lake herring) in spring. Warm-month bites cluster around early morning. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 30 ft | dawn & dusk | Deep basin (26 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 9 to 30 ft | dawn | Deep basin (26 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Gravel shoal (5 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 9 to 30 ft | dawn | Deep basin (26 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: lake whitefish sit in 9 to 30 ft that time of year. They don't go far with the seasons — 9 to 30 ft covers summer, 9 to 30 ft covers winter. The spot to know is Deep basin, a deep basin in about 26 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft | midday & dawn | Gravel shoal (5 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 9 to 30 ft | dawn | Deep basin (26 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Gravel shoal (5 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (26 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Feeding flat (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 9 to 30 ft before dropping to 9 to 30 ft for winter. Spring walleye concentrate at Gravel shoal, a prime-rated gravel shoal around 5 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft | dusk & night | Main-lake point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft | dusk & dawn | Deep basin (26 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
