Maiden Lake

On the LakeGrade rubric, Maiden Lake pulls an A: clarity at 80.4 ft and 10 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, Maiden Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake's 52 ft maximum depth is in the upper tier for Wisconsin — deep enough for cold-water fish to find refuge in summer. At 269 acres, Maiden Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Maiden Lake ranks 25 of 66 in Oconto County — solidly in the upper half of the local distribution.

Zebra mussels have been documented at Maiden Lake, which alters the filter-feeding balance and can paradoxically increase water clarity while disrupting the food web. The fishery includes walleye alongside the lake's other 4 documented species — a notable draw for Wisconsin anglers. A documented public access point at Maiden Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
