Get your wings out for the 20th annual Watershed Butterfly Festival! Every year, we celebrate this day of family fun to share the joys and wonders of nature.
Proceeds from this event help sustain our work in environmental conservation, advocacy, science, and education. The Watershed Institute is a member-supported non-profit dedicated to protecting and restoring clean water and healthy environments in central New Jersey.
The Watershed Center and Reserve are open daily. Attend a program, subscribe to our e-news, and become a member to stay involved in our work all year round! Thank you for your support.
