Steiger Lake
Carver County, MinnesotaEutrophic
Steiger 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.
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. Steiger Lake reaches 37 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 166 acres, Steiger Lake fits the Minnesota median for monitored lakes, with 2.3 miles of shoreline. Steiger Lake ranks 16 of 40 in Carver County — solidly in the upper half of the local distribution.
Eurasian watermilfoil is established at Steiger Lake, which can dampen recreational access and pressure the native plant community. Bass fishing is part of the appeal: the species list runs to 14, anchored by largemouth and/or smallmouth bass. A documented public access point at Steiger Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 15 times at Steiger Lake, with a median around Mar 30. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
