Moore Lake

Moore Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. At only 5 ft deep, Moore Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. Moore Lake is small — 68 acres alongside 1.7 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Moore Lake sits at rank 15 of 24 in Anoka County, in the lower half of the local distribution.

Moore 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 11 documented species across the lake's records. A documented public access point at Moore 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.
