About Hudson Valley Stream Conservancy

Hudson Valley Arts and Science is a tax exempt nonprofit that works in aquatic ecology, water-related infrastructure, environmental education and outreach. We’ve been around since 2006 and are supported by NY State and foundation grants. Our overriding goal is to protect and restore streams and rivers both for their ecological function and to help humans sustainably get the most out of interacting with nature; economically and recreationally.

We specialize in small community streams that have been long overlooked and work to bring them out of anonymity in their community. We do this by first researching the fish wildlife, the water quality, and the history of the streams and by then telling their stories using engaging interpretive signage, in-stream events, and village fair demonstrations. We get to point out, for instance, that ‘no, your stream is not a lifeless sewer, but has nine species of fish!”.

On the infrastructure front, we have been doing the design and permitting of a deep water pier into the Hudson in Ossining to be able to host educational tall ships like the Clearwater and the Freedom Ship Amistad. We’re also partnering with Westchester County Department of Planning to remove the

first dam on the Hutchinson River in Mt. Vernon to allow river herring to migrate upstream from the Atlantic Ocean in the spring to spawn.

So, research, infrastructure for restoration and public access and local stream history. That’s what we do. We need your help, please make a tax deductible donation today.
