West Sylvia Lake

West Sylvia 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.

Trophically, West Sylvia Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. At 97 ft of maximum depth, West Sylvia Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. At 904 acres, West Sylvia Lake fits the Minnesota median for monitored lakes, with 12.7 miles of shoreline. West Sylvia Lake ranks 4 of 64 in Wright County, putting it in the upper tier of locally monitored lakes.

Zebra mussel presence at West Sylvia Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. Walleye are documented at West Sylvia Lake, one of 15 fish species on record for the lake. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a partial ice record — 11 observed ice-outs, centered near Apr 23. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
