Rogers Lake

Rogers Lake earns a D — measurements through 2022 show persistent nutrient pressure that limits clarity through the summer. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

At a TSI of 57, Rogers Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. Rogers Lake is a shallow lake at 8 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. Rogers Lake covers 102 acres alongside 3.0 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Dakota County's 36 graded lakes, Rogers Lake ranks 23 — below the local median, though not at the bottom.

Rogers Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. The fishery is bass-led, with 7 documented species across the lake's records. A documented public access point at Rogers 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.
