Falk Lake

On the LakeGrade rubric, Falk Lake pulls an A: clarity at 13.3 ft and 14 µg/L of phosphorus put it in the top bracket for Minnesota. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI near 41 places Falk Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. The lake bottoms out at 33 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 73 acres, Falk Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Falk Lake ranks 17 of 40 in Clearwater County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Falk Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 9 documented species — a notable draw for Minnesota anglers. A documented public access point at Falk Lake 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.
