Cruson Slough Lake

Cruson Slough Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. Cruson Slough Lake is small — 80 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Cruson Slough Lake ranks 1 of 2 in Richland County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Cruson Slough Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Cruson Slough Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
