32-acre lake in Polk County, Wisconsin. The lake tops out around 49 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. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 32 acres, worked by 1.6 miles of shoreline. With a 2 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 34% of this chart, as modeled. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. It sits in Polk County. If the bite dies, Twin Lake is 0 mi to the west.
Spring rainbow trout on Twin Lakes hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Break off the point — drop-off, 22 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
