Toxic Algae in the Finger Lakes

Water Quality > Toxic Algae

Welcome to – an educational resource created by the nonprofit Finger Lakes Land Trust (FLLT) to inform our communities about an intensifying menace to water quality, public health, tourism, and local economies across the region.

In recent years, all 11 Finger Lakes have been struck by outbreaks of cyanobacteria, commonly called toxic algae or harmful algal blooms (HABs).  More than one million people depend on the lakes for their drinking water in Upstate New York.

Here we share toxic algae facts, resources, and actions to take.  We also report on how FLLT is working to secure our waters by collaborating with our partners as part of our broad Water Quality Initiative.

Please make a gift to support conservation.
