808-acre lake near Blue Earth County. The lake tops out around 5 ft. The depth data here comes from the Minnesota DNR survey of 1970, a decades-old survey (the DNR's original lake-survey map). Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 808 acres wrapped in 5.2 miles of bank. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 1.6 mi end to end and 1.1 mi across at its widest. Blue Earth County claims this one. Crystal sits 1 mi northwest — the closest neighbouring chart.
Spring puts walleye in skinny water — 1 to 5 ft is the zone. Summer fish stay in 2 to 5 ft, and winter fish hold in 2 to 5 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 5 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | dusk & dawn | Main-lake point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 5 ft | dusk & dawn | Break off the point (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

Start shallow in spring: yellow perch sit in 1 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 2 to 5 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

A bucktail or a weedless spoon over cabbage is the honest summer answer here.
