🚨 HAB activity is ramping up on Cayuga Lake. ⚠
Unfortunately, harmful algal bloom (HAB) activity is increasing this week. On Monday, 8/17, we received 14 HAB reports, and as of 2 PM today (Tuesday, 8/18), we’ve received another 7—for a total of 21 reports in just two days.
While this isn’t the highest number of reports we’ve received over a two-day period, it’s a notable increase: during the entire previous week, we received 15 reports total.
📍 13 of the 21 reports are from the western shoreline, stretching from Canoga to Taughannock Falls State Park.
If you’re out on Cayuga Lake, please keep an eye out for HABs and report what you see! Your observations help us track bloom activity and provide important information to the community.
