Jennie Lake

Jennie Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

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. A maximum depth of 15 ft puts Jennie Lake in the middle of Minnesota's depth distribution. With 1,069 acres of surface and 5.8 miles of shoreline, Jennie Lake is a large water by Minnesota standards — recreational pressure is spread across a long shoreline. Jennie Lake sits at rank 12 of 23 in Meeker County, in the lower half of the local distribution.

No invasive species are currently listed at Jennie Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 12 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
