Bloom Description
2025 PRIORITY SITE: Cayuga Marina & Outfitters- identified by Cayuga County Health Department as a sample-collection site. Volunteer Reports: The nature of the bloom seemed in flux as the sun intensified but the breeze has picked up. The currents seem to cause accumulation in different locations along the shoreline even within the fifteen minutes or so that we were on the site.
