Crow R Mill Pond
Kandiyohi County, MinnesotaEutrophic
Crow R Mill Pond earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.
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. At only 14 ft deep, Crow R Mill Pond is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. At 2,290 acres, Crow R Mill Pond is one of the larger lakes in Kandiyohi County, with 37.8 miles of shoreline supporting multiple distinct use patterns. Crow R Mill Pond ranks 11 of 35 in Kandiyohi County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Crow R Mill Pond — the lake remains off the Minnesota infested-waters roster. Walleye are documented at Crow R Mill Pond, one of 13 fish species on record for the lake. 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.

From the 2023-06-08 survey
A targeted trapnet survey of Middle Fork Crow Reservoir "MFCR", also known as Monongalia or Mud Lake, was conducted in early June of 2023. The purpose of the survey was to determine the extent of a partial winterkill in February/March of 2023. Four lake survey trapnets were set at standard stations. At least one…
