Straight Lake

Straight Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. The lake's 63 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. Straight Lake covers 471 acres alongside 9.8 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Straight Lake sits at rank 53 of 93 in Becker County, in the lower half of the local distribution.

Straight Lake has no invasive species recorded in Minnesota state databases as of 2021, though prevention practices still apply at all access points. Muskie are on the species list at Straight Lake, among the lake's 15 documented fish. Public access is available — the lake is on the Minnesota PCA public-access list. Ice-out has been recorded 9 times at Straight Lake, with a median around Apr 15. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
