Washte Lake

Washte Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Mesotrophic conditions dominate at Washte 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. At 81 acres, Washte Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Within Lake County's 142 graded lakes, Washte Lake ranks 79 — below the local median, though not at the bottom.

No invasive species are currently listed at Washte Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Washte Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. 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.
