Cruson Slough Lake

On the LakeGrade rubric, Cruson Slough Lake pulls an A: clarity at 25.1 ft and 29 µg/L of phosphorus put it in the top bracket for Wisconsin. 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.

Mesotrophic conditions dominate at Cruson Slough Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. 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.
