Rice Lake South Snail
Forest County, WisconsinLimited DataEutrophic
Rice Lake South Snail earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade.
Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. At only 6 ft deep, Rice Lake South Snail is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. The lake's 201 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. Rice Lake South Snail ranks 32 of 34 in Forest County — at the lower end of the locally monitored distribution.
Rice Lake South Snail has no invasive species recorded in Wisconsin state databases as of 2025, though prevention practices still apply at all access points. The fishery is bass-led, with 3 documented species across the lake's records. 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.
