The Sparkill Creek Watershed Alliance is a community action group committed to promoting environmental awareness, partnerships and practices that restore and preserve the health of the Sparkill Creek from its headwaters on Clausland Mountain to its confluence with the Hudson River in the Piermont Marsh.

This website was funded by a generous donation from Orange and Rockland Utilities Inc. The Sparkill Creek Watershed Alliance is grateful for its support.

The Sparkill Creek Watershed is nature’s address of where we live and work.
