Walter J. Sullivan Water Treatment Facility, 250 Fresh Pond Pkwy., Cambridge, MA 02138
Come to Black's Nook, a section of Fresh Pond Reservation, to take a closer look at water. Rangers will be there to help look for and identify the macro- and micro-wildlife that inhabit our City waters. Drop in for a bit or stay as long as you like, maybe even complete the 2.25mi stroll around Fresh Pond!
