Blueberry Lake

Blueberry Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Mesotrophic conditions dominate at Blueberry Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 47 ft puts Blueberry Lake in the middle of Minnesota's depth distribution. Blueberry Lake is small — 88 acres alongside 2.6 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Blueberry Lake sits at rank 47 of 93 in Becker County, in the lower half of the local distribution.

No invasive species are currently listed at Blueberry Lake — the lake remains off the Minnesota infested-waters roster. The fishery is bass-led, with 10 documented species across the lake's records. A documented public access point at Blueberry 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.
