LakeForecast water quality monitoring in 2023

Clean Lakes Alliance’s LakeForecast water quality monitoring program completed its 11th season in 2023. This program is entirely volunteer implemented, with 90 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, extent of floating plant debris, and the severity of green algae and cyanobacteria at public beaches, lakeside parks, and private piers. Submitted data can be seen in real-time on lakeforecast.org or our free app allowing the general public to stay up to date on current lake conditions.

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.

Fishing along Monona Bay

Out-of-town anglers drawn to downtown Madison lakes

Spend time walking along Lake Monona between Law Park and Brittingham Park, and you’ll notice anglers tossing lines from plenty of places. Unfortunately, there is a lack of accessible shoreline fishing locations. Folks fishing have to contend with hazards like the wall at the Monona Terrace or the railroad tracks…which are actually illegal to use for fishing. Still, the challenges of fishing on Lake Monona do not seem to stop diehard anglers from spending time doing what they love.

2022 Clean Boats, Clean Waters


In 2022, Clean Lakes Alliance received a Wisconsin DNR Surface Water Grant to participate in the Clean Boats, Clean Waters (CBCW) program. CBCW is a state-wide aquatic invasive species (AIS) prevention program. The program increases awareness and education to boaters, anglers, and general lake users on best practices to prevent the further spread of AIS at our local boat landings.

May2022 Training with FOLKS

LakeForecast water quality monitoring in 2022

 In 2022, our volunteers embarked on the 10th season of LakeForecast water quality monitoring. This work involved collecting nearshore condition reports at piers, beaches, parks, and access points around the five Yahara lakes. From May through September, volunteers measured water clarity, recorded air and water temperature, identified the presence of green algae and cyanobacteria, and noted additional visual observations. Reports are entered into the LakeForecast app where all data are updated in real time.

Aquatic plant transport barge on Lake Mendota

Aquatic plant harvesting on the Yahara lakes

The Dane County Land & Water Resources Department manages an aquatic plant harvesting program with much of the harvesting occurring on lakes Mendota, Monona, Waubesa, and Kegonsa. Occasionally, other smaller waterbodies are harvested to aid in recreation and invasive plant management. The program dates to the early 1980’s when five harvesters were in operation. In those years, harvests totaled over 300 tons of plant material. In 2021, the existing fleet of 12 harvesters recorded plant harvests of more than 12,000 tons!
