Majestic Lake
St. Louis County, MinnesotaLimited DataOligotrophic
Majestic Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota.
A TSI value of 37 puts Majestic Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake's 51 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. At 52 acres, Majestic Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Within St. Louis County's 187 graded waters, Majestic Lake sits at rank 6, near the top of the local distribution.
No invasive species are currently listed at Majestic Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Majestic Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. Ice-out has been recorded 10 times at Majestic Lake, with a median around Apr 22. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
