Moose Lake
Todd County, MinnesotaLimited DataMesotrophic
Moose Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. 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.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Moose Lake reaches 26 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 131 acres, Moose Lake fits the Minnesota median for monitored lakes, with 2.0 miles of shoreline. Within Todd County's 17 graded lakes, Moose Lake ranks 11 — below the local median, though not at the bottom.
No invasive species are currently listed at Moose Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 13 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. Ice-out has been recorded 9 times at Moose Lake, with a median around Apr 18. 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.

From the 2023-05-01 survey
Moose Lake has been managed with a reduced bag limit for sunfish since 2016 when a 10 fish bag limit was enacted. This bag limit was further reduced to 5 fish in 2021. Trap netting and daytime electrofishing were performed throughout the month of May 2023 in an effort to calculate a population estimate of Bluegills…
