Elbow Lake

On the LakeGrade rubric, Elbow Lake pulls an A: clarity at 26.2 ft and phosphorus readings still being added put it in the top bracket for Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI value of 30 puts Elbow Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's 234 acres and partial shoreline records put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Elbow Lake ranks 15 of 70 in Burnett County, putting it in the upper tier of locally monitored lakes.

Elbow Lake has no invasive species recorded in Wisconsin state databases as of 2019, though prevention practices still apply at all access points. The fishery is bass-led, with 2 documented species across the lake's records. A documented public access point at Elbow 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.
