Iverson Lake

Iverson Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. The lake bottoms out at 18 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. The lake is compact at 68 acres, with 1.6 miles of shoreline and little volume to buffer nutrient inputs. Iverson Lake sits at rank 63 of 97 in Otter Tail County, in the lower half of the local distribution.

Iverson Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. The fishery includes walleye among the lake's 6 documented species — a notable draw for Minnesota anglers. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
