Blooms Lake

On the LakeGrade scale Blooms Lake grades a B, with clarity at 6.9 ft and 19 µg/L of phosphorus placing it above the Minnesota median. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Blooms Lake reaches 41 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. Blooms Lake is small — 48 acres alongside 1.4 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Among the 31 graded lakes in Chisago County, Blooms Lake ranks 3 — in the top quartile locally.

No invasive species are currently listed at Blooms Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Blooms Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Blooms Lake — most use is by shoreline residents and their guests. Multiple sampling years from Minnesota PCA volunteers and partner agencies back the grade, so the letter should hold steady absent a major watershed shift.
