Rating depth structure for walleye.

689-acre lake near Big River. The lake tops out around 64 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:
The drawn water covers 687 acres wrapped in 6.9 miles of bank, broken up by 2 islands. With a 1.9 development index there's bank structure worth casting at, in moderation. About 53% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 1.8 mi of water from one end to the other, 1.1 mi at the beam. It sits in Division No. 16. If the bite dies, Millpond Lake is 2 mi to the southeast.
When the water first warms, burbot slide up into 19 to 64 ft. There's no big seasonal slide here — summer means 19 to 64 ft, winter 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 54 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 | 19 to 64 ft | night & dusk | Deep basin (54 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 19 to 64 ft | night & midday | Deep basin (54 ft) | Heavy jig + cut bait |
| Fall | 19 to 64 ft | night & dusk | Deep basin (54 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (54 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Summer pushes them deeper, 19 to 64 ft, and winter fish settle into 19 to 64 ft. The spot to know is Deep basin, a deep basin in about 54 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 | 15 to 45 ft | midday & dawn | Break off the point (29 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 19 to 64 ft | dawn | Deep basin (54 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (29 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 19 to 64 ft | midday & dawn | Deep basin (54 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 6 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 (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 29 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 | Main-lake point (16 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (29 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (29 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (29 ft) | Jigging spoon + minnow head, Rattle bait |
