Little Floyd Lake
Becker County, MinnesotaMesotrophic
Little Floyd Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
A TSI near 45 places Little Floyd Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Little Floyd Lake reaches 34 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 215 acres, Little Floyd Lake fits the Minnesota median for monitored lakes, with 2.2 miles of shoreline. Little Floyd Lake sits at rank 51 of 93 in Becker County, in the lower half of the local distribution.
Zebra mussel presence at Little Floyd Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. Walleye are documented at Little Floyd Lake, one of 16 fish species on record for the lake. A documented public access point at Little Floyd Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 6 times at Little Floyd Lake, with a median around Apr 17. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
