Cokato Lake

On the scoring rubric Cokato Lake grades a D: clarity at 6.0 ft and phosphorus readings still being added keep it in the lower bracket for Wright County.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. Cokato Lake is unusually deep for Minnesota at 52 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. The lake's 553 acres and 4.7 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within Wright County's 64 graded lakes, Cokato Lake ranks 35 — below the local median, though not at the bottom.

Cokato Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. Walleye are documented at Cokato Lake, one of 20 fish species on record for the lake. A documented public access point at Cokato Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
