Little Cowhorn Lake

Little Cowhorn Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Minnesota average.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. A maximum depth of just 12 ft means sediment-bound phosphorus releases back into the water column whenever wind stirs the bottom — a classic shallow-lake dynamic. The lake's 181 acres and 2.4 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Little Cowhorn Lake ranks 134 of 141 in Itasca County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Little Cowhorn Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Little Cowhorn Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Little Cowhorn Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
