As summer kicks off, experts are warning swimmers and boaters to watch for harmful algal blooms and invasive species in Cayuga Lake, according to Tompkins Weekly. Monitoring efforts by the Community Science Institute (CSI) are now focused on 14 high-risk sites after a record-breaking season in 2024.
Blooms, which can appear like green or paint-like scum, pose serious health risks to people and pets. Invasive hydrilla is also spreading, choking out native plants and disrupting recreation. Officials urge visitors to inspect and clean boats to prevent further contamination.
CSI and the Cayuga Lake Watershed Network are promoting public education, offering updates, and encouraging local volunteer efforts to protect the lake’s ecosystem.
