Rebecca Lake

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

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. Rebecca Lake reaches 30 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake's 263 acres and 3.1 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Among the 95 graded lakes in Hennepin County, Rebecca Lake sits at rank 27, above the county median.

Eurasian watermilfoil has been documented at Rebecca Lake, requiring shoreline management to keep dense mats from crowding native vegetation. Muskie are on the species list at Rebecca Lake, alongside the lake's 11 other documented fish. A documented public access point at Rebecca 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.
