Tea Cracker Lake

Tea Cracker Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. 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.

A TSI near 43 places Tea Cracker Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. The lake's 73 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. Tea Cracker Lake covers 345 acres alongside 3.8 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 93 graded lakes in Becker County, Tea Cracker Lake sits at rank 35, above the county median.

No invasive species are currently listed at Tea Cracker Lake — the lake remains off the Minnesota infested-waters roster. Walleye are documented at Tea Cracker Lake, one of 15 fish species on record for the lake. No formal public access is documented at Tea Cracker Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
