Eagle Lake

Eagle Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

A TSI near 50 places Eagle Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. The lake's 67 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. Eagle Lake covers 849 acres alongside 5.0 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Eagle Lake ranks 9 of 35 in Kandiyohi County — solidly in the upper half of the local distribution.

Zebra mussel presence at Eagle Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. The fishery includes walleye alongside the lake's other 17 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a partial ice record — 13 observed ice-outs, centered near Apr 6. 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.
