Jaskari Lake

Jaskari Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. 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 Carlton County's 33 graded lakes, Jaskari Lake ranks 23 — below the local median, though not at the bottom.

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