Wallkill River community form

Our Mission

There is no life without water, and the water that flows through our communities is our responsibility. A river we can swim in and eat from is both our right and our responsibility. The Wallkill River Watershed Alliance was founded to restore the Wallkill River to its prime, to act as the voice of the River, and to advocate for the restoration of its entire watershed, using whatever means we find necessary.

A Year in Review · Celebrating 10 Years

A Decade on the Wallkill

For 10 years the Wallkill River Watershed Alliance has worked to restore and protect the river through stewardship, science, and community. Here’s what’s ahead in 2026 — and how you can be part of it.

Upcoming Events & Opportunities

Volunteer Opportunity

HAB Watchers Reporting Program

Community science · Live dashboard

Join WRWA’s HAB Watchers — a community-science program that trains residents to spot and report Harmful Algal Blooms from land. The live dashboard pairs your reports with real-time weather and USGS flow data and feeds the NYSDEC NYHABS system. Open the HAB Watchers Dashboard.

Community Art

Wallkill Futures — NEA-Funded Events

May – August 22, 2026 · Exhibition at Unison Arts (Jul 17–Aug 22)

Community-engaged art on the Wallkill: floating wetland installations, river-trash printmaking, nature painting, riverside performances, and the launch of the ‘Future Water Commons,’ an 8×20-ft vessel celebrating the river’s ecology.

What We’re Working On in 2026

Harmful Algal Blooms

HABs Communication Toolkit & ECO HABIT

With Riverkeeper, the Hudson River Watershed Alliance, and Bard College, WRWA is building a HAB communications framework for the Wallkill. Coordinator Bobby Howe is piloting ECO HABIT — an interactive platform that trains residents to identify and report toxic blooms, integrating real-time monitoring into an early-warning system.

Clean Water

NYS DEC Clean Water Plan

The DEC is developing a Clean Water Plan for the Wallkill focused on phosphorus — identifying sources, setting a Total Maximum Daily Load (TMDL), and prioritizing reduction projects for future funding. Residents can help by limiting fertilizer and pesticide use, maintaining septic systems, and keeping native buffers along waterways.

Shawangunk Kill

Shawangunk Kill Watershed Project

With Hudsonia Ltd. and a freshwater mussel survey by SUNY Cobleskill, WRWA is producing a Watershed Characterization Report and convening a Shawangunk Kill Summit. Volunteers are needed for stream sampling, habitat assessment, and an advisory committee.

Get Involved

Memberships and donations support watershed projects, community-based monitoring, and the work planned for the Shawangunk Kill. Be part of the next decade on the Wallkill.

Harmful Algal Blooms (HABs) on the Wallkill

Still Waters, an environmental justice documentary recently produced by Marist College students, provides an interesting perspective on the recurring issue of Harmful Algal Blooms (HABs) on the Wallkill River. It can be viewed by clicking the image below. WRWA participates in a number of active projects to investigate the possible causes of HABs and measures to prevent these undesirable occurrences.
