Indiana Lake
Lake County, MinnesotaLimited DataOligotrophic
Indiana Lake earns an A — every scored parameter (clarity) rates among the best monitored waters in Lake County.
Trophically, Indiana Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 31 ft puts Indiana Lake in the middle of Minnesota's depth distribution. The lake's 143 acres and 2.0 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. 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. Bass fishing is part of the appeal: the species list runs to 7, anchored by largemouth and/or smallmouth bass. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
