Camp Lake
Swift County, MinnesotaLimited DataEutrophic
Camp Lake pulls a D on the LakeGrade rubric — phosphorus loading and limited clarity hold it below the Minnesota average.
At a TSI of 52, Camp Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. Camp Lake reaches 26 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake's 230 acres and 3.6 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Camp Lake ranks 1 of 3 in Swift County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Camp Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye among the lake's 12 documented species — a notable draw for Minnesota anglers. A documented public access point at Camp Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.

From the 2024-05-22 survey
A standard survey was conducted on Camp Lake during late May and early June of 2024. A targeted survey is generally used for sampling a specific kind of fish or time of year (i.e., spawning season, fall season, etc.) unlike a standard survey which samples a wider range of fish species during the summer months using…
