West Lake -Spread Eagle Chain

Florence County, WisconsinLimited DataOligotrophic

West Lake -Spread Eagle Chain sits at the top of the Wisconsin DNR grading rubric with an A, a mark reached by the cleanest lakes in Wisconsin. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. At 68 ft of maximum depth, West Lake -Spread Eagle Chain stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. West Lake -Spread Eagle Chain covers 104 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. West Lake -Spread Eagle Chain sits at rank 26 of 39 in Florence County, in the lower half of the local distribution.

West Lake -Spread Eagle Chain is on the Wisconsin infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. Walleye are documented at West Lake -Spread Eagle Chain, one of 5 fish species on record for the lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
