Neglige Lake
Lake County, MinnesotaLimited DataMesotrophic
Neglige Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Neglige Lake is unusually deep for Minnesota at 58 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. Neglige Lake is small — 32 acres alongside 1.5 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Neglige Lake sits at rank 72 of 142 in Lake County, in the lower half of the local distribution.
Neglige Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. The lake's fish records list 1 species — a varied community without one dominant gamefish. No formal public access is documented at Neglige 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.
