8/12 Water Quality Notice:

  • Leddy Beach is closed due to cyanobacteria too. That makes all swimming areas closed.
  • Oakledge Cove and Blanchard Beach, as well as North Beach and Texaco are closed to swimming due to cyanobacteria.
  • North Beach access was restricted this morning for crews to clear storm debris. It should be cleared this afternoon to allow park access.
  • DPW has posted 48 hour advisory notices at Oakledge Cove, Blanchard Beach, Blodgett Access and Perkins Pier.
More details from DPW: Last night, Burlington’s Main Wastewater Treatment Plant switched over to backup generation during a widespread power outage in Burlington during the massive thunderstorm. While backup generation did turn on, disinfection pumps did not immediately start. Operators were on-site to diagnose and fix this issue. This did lead to a treated but not fully disinfected discharge from the Plant. This may lead to higher bacteria levels in nearby water. Due to proximity and in accordance with state law, we advise against contact recreation (e.g., swimming) at Oakledge Cove, Blanchard Beach, Blodgett Access and Perkins Pier for 48 hours. Visit burlingtonvt.gov/dpw for more information on Water Resources.

Water Quality Notice for 5.29.2020

Signs will be posted at those locations. A longer update will be posted to burlingtonvt.gov/dpw/press-releases.
