Weaver Lake

Weaver Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. clarity and phosphorus rate similarly, so there is no obvious single lever to pull on watershed management.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. At 57 ft of maximum depth, Weaver Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. At 152 acres, Weaver Lake fits the Minnesota median for monitored lakes, with 2.5 miles of shoreline. Among the 95 graded lakes in Hennepin County, Weaver Lake sits at rank 31, above the county median.

Eurasian watermilfoil has been documented at Weaver Lake, requiring shoreline management to keep dense mats from crowding native vegetation. Muskie are on the species list at Weaver Lake, among the lake's 15 documented fish. A documented public access point at Weaver Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
