You’re herring that right–we need you to count migratory fish!
Join our third-annual Charles River Herring Count! We’re looking for volunteers to count migratory fish at Watertown Dam.
EACH SPRING, THOUSANDS OF MIGRATORY FISH RETURN TO THE CHARLES RIVER TO SPAWN FROM THE OCEAN. BUT, MANY ARE STOPPED SHORT OF DEFUNCT DAMS.
We need YOU to help us collect data on how many fish are able to use the ladder at Watertown Dam! By counting fish, you will play a critical role in our understanding how dams affect American Shad, Blueback Herring, Alewives, Rainbow Smelt, White Perch, Striped Bass, and American Eel.
Watch our training video and schedule a timeslot today!
