Lake Wilipyro

On the LakeGrade rubric, Lake Wilipyro pulls an A: clarity at 34.5 ft and 14 µg/L of phosphorus put it in the top bracket for Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Trophically, Lake Wilipyro reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 25 ft puts Lake Wilipyro in the middle of Wisconsin's depth distribution. Lake Wilipyro is small — 72 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Lake Wilipyro ranks 25 of 55 in Bayfield County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Lake Wilipyro — the lake remains off the Wisconsin infested-waters roster. Bass fishing is part of the appeal: the species list runs to 3, anchored by largemouth and/or smallmouth bass. 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.
