Fisher Lake

Fisher Lake grades an F: water clarity, phosphorus, and chlorophyll-a all rate poorly, placing it among the most stressed lakes monitored in Minnesota. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

A TSI above 70 puts Fisher Lake in hypereutrophic territory: visible blooms are common, and clarity rarely climbs even in early summer. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Within the 17 graded lakes of Scott County, Fisher Lake sits at rank 15, near the bottom of the county list.

No invasive species are currently listed at Fisher Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Fisher Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Fisher 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.
