Indiana Lake

Indiana Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Lake County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. A maximum depth of 31 ft puts Indiana Lake in the middle of Minnesota's depth distribution. At 143 acres, Indiana Lake fits the Minnesota median for monitored lakes, with 2.0 miles of shoreline. Within Lake County's 142 graded waters, Indiana Lake sits at rank 23, near the top of the local distribution.

Indiana Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. The fishery is bass-led, with 7 documented species across the lake's records. No formal public access is documented at Indiana 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.
