Payson Park Reservoir provides storage and pressure for the City of Cambridge Water Supply system. Built in 1897, the off-stream reservoir is 900 feet long by 700 feet wide and is separated into a north and south basin by a granite masonry division wall. The earth embankment that surrounds the reservoir is about 2,225 feet long with a maximum height of 30 feet. Controls for the conduits discharging into and out of the reservoir are located in a gatehouse on the east side of the reservoir. The reservoir and embankment are generally in fair condition. The following deficiencies were observed at the site cracking and leaking of the gunite lining in the north basin, severe rusting of the inflow and outflow conduits, erosion of exterior slopes along the south end of reservoir, growth of brush and saplings on the slope at the southwest corner of the reservoir, trees growing along the toe of the embankment, and several repairs needed in the gate house. A significant amount of seepage is also passing through the underdrain system. Some movement of the brick masonry in the manhole to the weir chamber east of the gatehouse was also detected. The reservoir can contain 100 percent of the test flood without overtopping the embankment.
