Notification of Treatment on Lake Silver
In an effort to address the ongoing TMDL (Total Maximum Daily Load) for nutrients and to reduce the potential for an excessive algal bloom, the City’s Streets and Stormwater Division has chosen to treat Lake Silver with 5 applications of aluminum sulfate (alum).
If weather permits, the first round of treatment days will be on March 31, April 1, and April 4, 2022. Tanker trucks will be set up on Maury Road and Ardsley Drive. The alum will be applied by boat throughout the entire waterbody. During the application process, no boating activities should occur. After completion each application day, boating and any normal water related activities may resume to normal. Irrigation can be used as normal during the treatment process.
After each application, the City will continue to monitor the lake's status and address any issues that may occur.
