Help stop Didymo before it stops your fishing, boating, swimming…
What’s didymo?
It’s a microscopic alga known as a diatom that’s invading our rivers and streams. Didymosphenia geminata, also known as ‘rock snot’ or ‘didymo’, can smother entire stream beds with mats as thick as eight inches and can ruin just about any river or creek.
What does it look like?
Didymo can be found on rocks in moving water and is often mistaken for fiberglass or toilet tissue. Unlike most other algae, didymo feels like wet cotton and isn’t slimy. It is generally brown, tan or yellow in color.
Where is it?
Didymo has been confirmed in the East and West Branches of the Delaware River (New York and Pennsylvania) as well as in the Delaware River mainstem as far south as Callicoon, New York
