Clean Lakes Alliance Statement to Dane County Lake Level Task Force

This statement was presented by Clean Lakes Alliance Executive Director James Tye to the Dane County Lake Level Task Force on March 5, 2019.

Clean Lakes Alliance applauds the leadership of the Dane County Board and the Dane County Executive in putting $12 million toward flood recovery and lake improvement projects in the 2019 budget, and in creating the Technical Work Group and task force to address recent flooding around the Yahara Chain of Lakes. We believe these initiatives help move us toward becoming a more resilient community. But we need to work together as a community to address the increasing volume of water and runoff BEFORE it enters our lakes and waterways.

Yahara Lakes 2018 Water Quality Monitoring Results

Overview

From May to September of 2018, water quality monitoring took place at piers and beaches around the five Yahara lakes. Volunteers measured near-shore water clarity, air and water temperature, and noted several visual observations. Visual observations included presence of algal blooms (green/blue-green), floating plant debris, swimmers, waterfowl, wave intensity, and general water appearance. Volunteers report conditions on our website, Lakeforecast.org. The website displays updated data in real time.

Highlights

  • 79 near-shore and 7 offshore monitoring stations on all five Yahara lakes (Figure 1)
  • Weekly off-shore measurement of Secchi depth on all five lakes
  • Measured temperature and dissolved oxygen profiles on all five lakes (seven sites total)
  • Weekly monitoring continued at all 25 public beaches
  • 44% increase in number of condition reports from 2017 (Table 1)
  • Collected continuous near-shore temperature measurements at 17 sites on lakes Mendota, Monona, and Waubesa, and Kegonsa

In the Yahara Watershed, salt applied to roads and sidewalks ultimately makes its way into our lakes and our drinking water. Road salt has been used as a deicer on streets in Dane County since the 1950s, and over the last 50 years, average concentrations of chlorides from salt in our lakes have steadily increased.
