Lakeshore State Park Fish Shocking
Milwaukee County, WisconsinLimited DataMesotrophic
Lakeshore State Park Fish Shocking earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
A TSI near 47 places Lakeshore State Park Fish Shocking in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. 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 3 of 14 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.
