North Tamarac Lake

North Tamarac Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. North Tamarac Lake reaches 17 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. North Tamarac Lake covers 1,442 acres alongside 12.4 miles of shoreline, large enough that conditions can vary meaningfully between bays. North Tamarac Lake ranks 89 of 102 in Becker County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at North Tamarac Lake — the lake remains off the Minnesota infested-waters roster. Walleye are documented at North Tamarac Lake, one of 12 fish species on record for the lake. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
