Indian Lake

Wright County, MinnesotaEutrophic

The LakeGrade rubric puts Indian Lake at a C: clarity at 7.6 ft, 33 µg/L of phosphorus, and a TSI of 51 signal an intermediate trophic state. With clarity and phosphorus scored, the sub-grades cluster within a letter of each other, pointing to stable conditions rather than one specific stressor.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. A maximum depth of 31 ft puts Indian Lake in the middle of Minnesota's depth distribution. Indian Lake covers 139 acres alongside 2.6 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 64 graded lakes in Wright County, Indian Lake sits at rank 26, above the county median.

Eurasian watermilfoil is established at Indian Lake, which can dampen recreational access and pressure the native plant community. Bass fishing is part of the appeal: the species list runs to 9, anchored by largemouth and/or smallmouth bass. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a partial ice record — 9 observed ice-outs, centered near Apr 19. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2025-05-05 survey

A reduced daily bag limit on sunfish (10 fish daily) was enacted on Indian Lake (Wright County) beginning March 1, 2021. To evaluate the effectiveness of this regulation and to monitor size structure in the Bluegill population, targeted Bluegill assessments were conducted on Indian Lake in 2017, 2021, and 2025.…
