236-acre lake near Cook County. The lake tops out around 60 ft. The depth data here comes from the Minnesota DNR survey of 1982 (the DNR's original lake-survey map). The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 236 acres of water rimmed by 6.7 miles of bank. The 3.1 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 34% of this chart. The basin spans about 2.8 mi end to end and 0.4 mi across at its widest. You'll find it in Cook County. For a second option, East Otter lies 1 mi northeast.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 18 to 60 ft before dropping to 15 to 60 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 60 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 60 ft | dawn | Deep basin (60 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (13 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 60 ft | dawn | Deep basin (60 ft) | White tube jig, Airplane jig |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. Break off the point is the standout, a drop-off at roughly 8 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (13 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (13 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (8 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 20 to 45 ft for winter. The spot to know is Main-lake point, a point in about 13 ft of water that rates prime for smallmouth bass in fall. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (13 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (13 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (13 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (8 ft) | Blade bait, Hair jig |
