Cedar Lake

Cedar Lake earns a D — measurements through 2024 show persistent nutrient pressure that limits clarity through the summer. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

At a TSI of 59, Cedar Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. 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 33 graded lakes of Carlton County, Cedar Lake sits at rank 26, near the bottom of the county list.

No invasive species are currently listed at Cedar Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Cedar Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Cedar Lake — most use is by shoreline residents and their guests. The grade is supported by multiple sampling years from Minnesota PCA volunteers and partner agencies, giving the letter a reasonably stable foundation.
