The Watershed Division publishes annual results from the SWQMP to an interactive Source Water Quality Report. This interpretive report allows users to explore water quality topics of interest in the Cambridge watershed and Fresh Pond Reservoir, visualize long term and emerging water quality trends, and learn about Cambridge’s overall surface water supply system. The report also compares SWQMP data against United States Geological Survey baseline data collected in 1997 and 1998. First published in October 2022, the Source Water Quality Report replaces annual water quality pdf reports that were previously issued to characterize source water chemistry.

Although separate from the drinking water supply system, the Watershed Division monitors water quality in three small ponds located on Fresh Pond Reservation: Blacks Nook, Little Fresh Pond, and North Pond. The Watershed Division produces annual reports used by City of Cambridge Clean Water Act reporting requirements.
