Boot Lake

The LakeGrade rubric puts Boot Lake at a C: clarity at 6.7 ft, 31 µg/L of phosphorus, and a TSI of 52 signal an intermediate trophic state. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

At a TSI of 52, Boot Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. The lake bottoms out at 19 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Boot Lake is small — 91 acres alongside 2.6 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Boot Lake ranks 9 of 24 in Anoka County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Boot Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Boot Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Boot Lake — most use is by shoreline residents and their guests. 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.
