Lakeshore State Park Fish Shocking

Milwaukee County, WisconsinLimited DataOligotrophic

Lakeshore State Park Fish Shocking 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.

Trophically, Lakeshore State Park Fish Shocking reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Lakeshore State Park Fish Shocking ranks 2 of 15 in Milwaukee County, putting it in the upper tier of locally monitored lakes.

No invasive species are currently listed at Lakeshore State Park Fish Shocking — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Lakeshore State Park Fish Shocking, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
