Bloom Description

2026 PRIORITY ZONE: Frontenac Park- identified by Cayuga County Health Department as a sample-collection site. Volunteer reported: 90 degrees, humid, windy, large waves but no white caps, mostly sunny. LOTS of boat traffic.....The additional picture here is the stream entering the lake at Frontenac Park. I do not take samples from here but thought it was interesting due to the two colors of HABS. It seems.
