85-acre lake near Itasca County. The lake tops out around 13 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. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 85 acres wrapped in 1.4 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 0.5 mi end to end and 0.4 mi across at its widest. It sits in Itasca County. If the bite dies, Bluebill is 1 mi to the northwest.
Start shallow in spring: walleye sit in 3 to 13 ft that time of year. They don't go far with the seasons — 4 to 13 ft covers summer, 4 to 13 ft covers winter. Top water on the chart: Shoreline break, a drop-off in the 6 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.

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