Make a donation to support clean water and a healthy Hudson!

No act of generosity is too small to make a difference.

Riverkeeper is thrilled to once again come together at its 2023 Summer Splash gala to celebrate the Hudson River and the long-time activists and heroes who are fighting to keep it safe and clean. Summer Splash will be held at Boscobel House and Gardens, a beautiful historic estate in Garrison, NY with some of the best Hudson River views around.

We are proud to honor Fran Dunwell with our 2023 Big Fish Award in recognition of her decades fighting for the Hudson River as the founder and coordinator of the Hudson River Estuary Program at the NYS Department of Environmental Conservation. We are also pleased to present our Hudson Hero Award to Dr. David O. Carpenter, environmental advocate and professor at SUNY Albany, for his work highlighting risks from environmental contaminants in New York State, including PCBs in the Hudson and related dumping sites.

Your ticket purchase or generous donation to the Summer Splash will provide crucial support for our work protecting and restoring the Hudson River and its tributaries and safeguarding drinking water for millions of New Yorkers. We hope you'll join us as we come together once again to celebrate our clean water victories and renew our shared commitment to the Hudson River.

Dinner will be served. Garden party attire recommended. 


Big Fish Award Honoree
Fran Dunwell


Fran Dunwell recently retired as the Hudson River Estuary Coordinator at the NYS Department of Environmental Conservation (NYSDEC), a position she held from 1984-2022. In that role, she managed the implementation of the state's Hudson River Estuary Action Agenda and its $6.5 million annual budget. The Estuary Program organizes many partners to conserve the tidal Hudson and the extraordinary natural heritage of its watershed, using programs founded in science and implemented in ways that support the quality of life of the valley's residents. Prior to working for NYSDEC, she was Executive Director of the Center for the Hudson River Valley, and then Associate Director of Scenic Hudson. Dunwell has a Master's degree in environmental studies from Yale University and a Bachelor's degree in anthropology from Kirkland College.
