70-acre lake near Clearwater County. The lake tops out around 47 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
The outline encloses 70 acres, worked by 1.7 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 51% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.7 mi with a 0.2-mi widest point. It sits in Clearwater County. If the bite dies, First is 1 mi to the east.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. The spot to know is Shoreline break, a drop-off in about 21 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Shoreline break (21 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Shoreline break (21 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (40 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 6 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.
