142-acre lake near Lake County. The lake tops out around 15 ft. The depth data here comes from the Minnesota DNR survey of 1969, a decades-old survey (the DNR's original lake-survey map). Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 142 acres wrapped in 2.8 miles of bank. With a 1.7 development index there's bank structure worth casting at, in moderation. Figure 0.9 mi of water from one end to the other, 0.5 mi at the beam. It sits in Lake County. Its nearest charted neighbour, Christianson, is 2 mi to the northeast.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 5 to 15 ft before dropping to 5 to 15 ft for winter. The spot to know is Deep basin, a deep basin in about 15 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |

Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
