The Cambridge Water Department (CWD) is a municipally owned and operated water utility serving over 100,000 permanent residents. The department is under the general direction of the City Manager, while a five-member Water Board, made up of Cambridge residents appointed by the City Manager, serves as an advisory group to the Department.

  • Monarch Butterfly Release Celebration

    Aug 18, 2019 2:00 PM - 3:30 PM

    The sixth annual raising and releasing of monarch butterflies by the Cambridge Water Department at Fresh Pond Reservation has begun! From now until the public release ceremony in August you can view the caterpillars’ progress in the Ranger Station at Fresh Pond. The Cambridge Water Department sees this as an opportunity to partner and engage with the public for the benefit of both the monarch butterfly population and Cambridge’s drinking water supply in the urban wild of Fresh Pond Reservation—which was recognized last summer as a migratory monarch waystation after 5 years of propagating milkweed plants and monarch butterflies. This raise-and-release project combines volunteer stewardship and public education activities at Fresh Pond Reservation to encourage a monarch population in the beautiful City of Cambridge. Migratory monarch populations travel between New England and Mexico and have been in decline nationally since the 1990s, it is largely believed that habitat loss is the driving factor in that decline. Good habitat conditions for monarchs are often conditions that are also essential for healthy watersheds. The monarch butterfly release celebration is scheduled for Sunday, August 18th, from 2:00-3:30pm at the Walter J. Sullivan Water Treatment Facility (250 Fresh Pond Parkway). See the butterflies up close, learn about their migration, complete the free activity booklet for a Jr. Range badge, and enjoy kids’ crafts! The release will begin at approximately 2:35pm in the meadow of the adjacent Kinglsey Park at Fresh Pond.
