65-acre lake near Big Stone County. The lake tops out around 9 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 65 acres wrapped in 1.5 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 0.6 mi, about 0.3 mi across. It sits in Big Stone County. Its nearest charted neighbour, North Rothwell, is 2 mi to the southwest.
The spring pattern is a shallow one: walleye in 2 to 9 ft. The depth story barely changes: 3 to 9 ft through summer, 3 to 9 ft in winter. The spot to know is Shoreline break, a drop-off in about 4 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Shoreline break (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 9 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Shoreline break (4 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 9 ft chart-limited; documented 12 to 40 ft | dusk & night | Shoreline break (4 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 9 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (8 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 2 to 9 ft. Summer keeps them at 3 to 9 ft, and they winter in 3 to 9 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 9 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 9 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 9 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (8 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts black bullhead in skinny water — 2 to 9 ft is the zone. Summer fish stay in 2 to 9 ft, and winter fish hold in 3 to 9 ft. Deep basin is the standout, a deep basin at roughly 8 ft, rated prime for winter black bullhead. Plan around after dark and the evening in the warm months.
