Where the dues go

Stock the lake.

Members fund the fish. Each fall, the Association partners with the Minnesota DNR's Detroit Lakes hatchery to release walleye fingerlings into Cotton Lake. The 2026 goal is 18,000 fish — every $25 stocks roughly 100 fingerlings.

The lake you already love

You know what we have
here.

1,763 acres. 13 miles of shoreline. A clear‑water walleye fishery, twelve miles east of Detroit Lakes. The Cotton Lake Association exists so the next generation gets the same lake we did — quiet, clean, and full of fish.

Cotton Lake Association Sixty‑three years of stewardship.

We're a volunteer‑run, non‑profit group of lakeshore owners and friends. Membership dues and store revenue go straight to the lake — fish stocking, water testing, weed harvest, AIS prevention, the events. Not to overhead.

If you've owned property here for a while, you've already enjoyed the work. Becoming a member is how that work keeps happening.

Reminder: the loon family on the north end has two chicks again this year. Please give them a wide berth and slow down through the narrows. They've made it three summers in a row 🥹
