Bloom Description
2026 PRIORITY ZONE: East Shore Park- identified by Tompkins County Whole Health as a sample-collection site. The HAB extends from East Shore Park north along East Shore drive and beyond in both directions along the shore. I do not know the full extent. Water quality relatively clear on lake side of HAB - in deeper water.
