Davis Lake

Davis Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade.

Mesotrophic conditions dominate at Davis Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. At 64 ft of maximum depth, Davis Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. The lake's 323 acres and 10.5 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 Cook County's 128 graded lakes, Davis Lake ranks 82 — below the local median, though not at the bottom.

No invasive species are currently listed at Davis Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Davis Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. 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.
