Snyder Lake

Hennepin County, MinnesotaLimited DataHypereutrophic

Snyder Lake grades an F: water clarity, phosphorus, and chlorophyll-a all rate poorly, placing it among the most stressed lakes monitored in Minnesota. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI above 70 puts Snyder Lake in hypereutrophic territory: visible blooms are common, and clarity rarely climbs even in early summer. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Within the 95 graded lakes of Hennepin County, Snyder Lake sits at rank 95, near the bottom of the county list.

No invasive species are currently listed at Snyder Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Snyder Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Snyder 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.
