17,280-acre lake near Whitemouth. The lake tops out around 10 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 16,956 acres wrapped in 35.9 miles of bank, with a single island in the mix. A middling shoreline index (2) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 7.8 mi long by 5.3 mi wide at the broadest reach. Division No. 1 claims this one. Moose Lake sits 17 mi east — the closest neighbouring chart.
Start shallow in spring: walleye sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. The spot to know is Creek inflow, an inflow / creek mouth in about 4 ft of water that rates prime for walleye in spring. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dusk & dawn | Creek inflow (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 10 ft | dusk & dawn | Sharp break (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 10 ft | dusk & night | Sharp break (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 10 ft | dusk & dawn | Deep basin (10 ft) | Jigging spoon + minnow head, Rattle bait |
Spring northern pike on Whitemouth Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 3 to 10 ft, and by winter most fish are in 3 to 10 ft.

When the water first warms, brook trout slide up into 1 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 2 to 10 ft. Start at Creek inflow. It's an inflow / creek mouth holding about 4 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
