Walker Bay Lake

Walker Bay Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. 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.

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. Walker Bay Lake ranks 39 of 133 in Cass County — solidly in the upper half of the local distribution.

Walker Bay Lake is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. The state fisheries records do not list documented species for Walker Bay Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Walker Bay Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a long ice-out record — 71 observations on file, with a median ice-out around Apr 28. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
