Woman Lake

Woman Lake earns an A — every scored parameter (clarity and phosphorus) rates among the best monitored waters in Cass County. clarity and phosphorus rate similarly, so there is no obvious single lever to pull on watershed management.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. 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. Woman Lake ranks 53 of 132 in Cass County — solidly in the upper half of the local distribution.

Zebra mussel presence at Woman Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. The state fisheries records do not list documented species for Woman Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Woman 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.
