Mueller Lake

Mueller Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. A maximum depth of 36 ft puts Mueller Lake in the middle of Minnesota's depth distribution. Mueller Lake is small — 24 acres alongside 1.5 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Mueller Lake ranks 59 of 142 in Lake County — solidly in the upper half of the local distribution.

Mueller Lake has no invasive species recorded in Minnesota state databases as of 2021, though prevention practices still apply at all access points. 3 fish species are documented at Mueller Lake, a mixed warm-water community typical for Minnesota lakes of this size. No formal public access is documented at Mueller Lake — most use is by shoreline residents and their guests. 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.
