Chartley Pond Dam is a 200-foot long 10-foot high earthfill dam built in the 1800s. A two-lane paved roadway is the crest of the dam while the downstream face includes a concrete wall and portions of the foundations for two structures. The embankment is in good condition but minor maintenance is required. Water discharges through a small outlet controlled by stop logs. An outlet at the dam for a water wheel is blocked and abandoned. An outlet controlled by removable stop logs functions as the spillway for the dam. Hydraulic analyses indicate that the outlet can discharge a flow of 170 cfs before overtopping the dam at El 105.6. This discharge represents 14 percent of the outflow test flood test flood discharge of 1,230 cfs. The outflow test flood which crests at EL 107.3 will overtop the dam by 1.7 feet. Draining the pond to El 96.5 prior to the outflow test flood will not appreciably reduce the amount of overtoping. The outlet cannot pass the test flood even with all stop logs removed, and overtopping of 1.2 feet will occur.
