2025 nearshore training

LakeForecast water quality monitoring in 2025

Clean Lakes Alliance’s LakeForecast water quality monitoring program completed its 13th season in 2025. This program is entirely volunteer implemented, with more than 100 trained monitors assessing water quality conditions from nearshore and offshore locations across all five Yahara lakes (Mendota, Monona, Wingra, Waubesa, and Kegonsa).

From Memorial Day through Labor Day, volunteers recorded water clarity, air and water temperature, waterfowl presence, the extent of floating plant debris, and the severity of green algae and cyanobacteria at public beaches, lakeside parks, and private piers. Submitted condition reports were able to be tracked in real-time on Lakeforecast.org or our free app, allowing the general public to stay up to date on current lake conditions.

Lakes can be surprisingly noisy in winter. Ice fractures and cracks are constantly forming through these cold winter months, causing audible sounds ranging from a slight echoing “blooop” sound to a startling or explosive “bang!” Why exactly are our icy lakes so loud?

Ice isn’t always as solid as it looks

Although lake ice appears stable and solid, it is an ever-shifting material subject to ever-changing forces. Unlike nearly every other substance or material, the volume of water significantly expands as it freezes, increasing the given volume of water about 9% after freezing. The expansion can induce incredible amounts of pressure onto the ice. Think about how frozen water can cause metal pipes to bend and burst.

Lake Waubesa Conservation Association primed to take action

By Carolyn Betz, Project Manager and Lead Author of the Lake Waubesa Management Plan

Lake Waubesa Conservation Association and the Wisconsin Department of Natural Resources approved a comprehensive lake management plan in late 2024. The plan presents an up-to-date analysis of historical and current water quality data, the unique wetlands, and phosphorus inputs from rural and urban land uses. The plan presents dozens of recommendations to protect and improve the lake.

Henry Vilas Park (Lake Wingra)

Henry Vilas Park is one of Madison’s oldest lakeside parks, and provides a gathering place along Lake Wingra for swimming, fishing, and even ice skating when the lagoon freezes over. The park was created from a 1904 donation from Wisconsin’s U.S. Senator, William Freeman Vilas (1840-1908), to the Madison Park and Pleasure Drive Association, an organization committed to the development of parks and scenic drives in the Madison area in the late 19th and early 20th centuries. Vilas also served as U.S. Postmaster General and Secretary of the Department of the Interior under President Grover Cleveland. Henry Vilas Park is named in memory of William’s son who died in childhood.
