200-acre lake near Douglas County. The lake tops out around 18 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What follows comes from the same scoring engine that paints the spots above.
Long maps at 200 acres behind 3.9 miles of shoreline. A middling shoreline index (1.9) gives it some bays to work without being a maze. 93% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 1.6 mi, about 0.4 mi across. It sits in Douglas County. Jennie sits 1 mi south — the closest neighbouring chart.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Break off the point, a drop-off in the 8 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.
