72-acre lake near Otter Tail County. The lake tops out around 21 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 72 acres wrapped in 2.4 miles of bank. A middling shoreline index (2) gives it some bays to work without being a maze. 77% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 0.7 mi with a 0.4-mi widest point. It sits in Otter Tail County. If the bite dies, Bass is 1 mi to the south.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 6 to 21 ft; cold water stacks them in 6 to 21 ft. Top water on the chart: Break off the point, a drop-off in the 9 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
