133-acre lake near Wright County. The lake tops out around 40 ft. The depth data here comes from the Minnesota DNR survey of 1955, a decades-old survey (the DNR's original lake-survey map). Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 133 acres, worked by 2.5 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 42% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.9 mi, about 0.5 mi across. Wright County claims this one. Ember sits 2 mi southwest — the closest neighbouring chart.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Deep basin, a deep basin in about 40 ft of water that rates prime for walleye in winter. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (10 ft) | 1/8 oz jig + minnow, Hair jig |

A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
