328-acre reservoir in Marinette County, Wisconsin. The lake tops out around 40 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. Below is the species-by-species picture, pulled from the same data the map uses.
Little Quinnesec Falls Flowage maps at 331 acres behind 11.1 miles of shoreline — one island included. An index of 4.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 91% of this chart, as modeled. Figure 3.1 mi of water from one end to the other, 1.5 mi at the beam. It sits in Marinette County.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Deep basin, a deep basin in the 34 ft range, prime in winter. 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.
