Bluewater Lake

Bluewater Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Itasca County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Trophically, Bluewater Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake's 120 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. Bluewater Lake covers 364 acres alongside 4.6 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Itasca County's 141 graded waters, Bluewater Lake sits at rank 20, near the top of the local distribution.

Bluewater Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. Walleye are documented at Bluewater Lake, one of 15 fish species on record for the lake. The lake lacks a documented public access point, so visitor use is limited. The lake has a partial ice record — 8 observed ice-outs, centered near Apr 23. 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.
