OARS Celebration of 3 Remarkable Rivers

Join us for a summer of celebration!

In celebration of OARS’ 40th year, we are bringing new events and renewed energy to the rivers we call home. From cleanups and invasive species removal parties, to community festivities and live music, there is something for everyone to connect with. Enjoy the beauty, serenity, and fun of the Sudbury, Assabet, and Concord rivers this summer with OARS and community partners, sponsored by the SuAsCo River Stewardship Council.
