168-acre lake near Cass County. The lake tops out around 10 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
Twin maps at 168 acres behind 3.2 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 1.2 mi long by 0.4 mi wide at the broadest reach. It sits in Cass County. If the bite dies, Little Twin is 1 mi to the south.
Start shallow in spring: walleye sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 3 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.
