Fish Hook Lake

Fish Hook Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Fish Hook Lake reaches 47 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. Fish Hook Lake covers 230 acres alongside 4.1 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Fish Hook Lake sits at rank 52 of 93 in Becker County, in the lower half of the local distribution.

No invasive species are currently listed at Fish Hook Lake — the lake remains off the Minnesota infested-waters roster. Walleye are documented at Fish Hook Lake, one of 10 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.
