Crow River Mill Pond

Kandiyohi County, MinnesotaLimited DataMesotrophic

Crow River Mill Pond comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Mesotrophic conditions dominate at Crow River Mill Pond: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. At only 14 ft deep, Crow River Mill Pond is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. With 2,290 acres of surface and 37.8 miles of shoreline, Crow River Mill Pond is a large water by Minnesota standards — recreational pressure is spread across a long shoreline. Crow River Mill Pond ranks 7 of 35 in Kandiyohi County, putting it in the upper tier of locally monitored lakes.

Crow River Mill Pond has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. Walleye are documented at Crow River Mill Pond, one of 13 fish species on record for the lake. A documented public access point at Crow River Mill Pond makes the lake usable for shore fishing, paddle craft, and trailered boats. 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…
