National Program for Inspection of Non-Federal Dams. Mill Pond Dam (MA 00027), Wareham River Basin, Wareham, Massachusetts. Phase I Inspection Report.
Abstract
Mill Pond Dam is an earth embankment dam believed to have been constructed around 1900. The facility is used as a bridge across the Agawam River and to impound water for recreational purposes. The dam is about 285 ft. long and 16.5 ft. high. The dam has two spillways. The primary spillway is a concrete sluiceway located near the left abutment. A two bay stoplog structure located at the downstream end of the sluiceway controls flows through the facility. The secondary spillway is a 5 ft. dia. metal pipe culvert located on the right side of the dam. A stoplog structure having a weir length of 5.4 ft. is located on the upstream end of this spillway. An 18 in. dia. outlet passes through the dam near mid-point. Outflow is controlled at a 6 ft. by 8 ft. by 6 ft. upstream concrete intake structure. The dam and appurtenant works are judged to be in fair condition. There is no low level outlet for draining the pond. Seepage was noted at four locations. There was erosion of both the upstream and downstream embankments in the vicinity of the 18 in. dia. outlet pipe. Tree and brush growth is abundant. The test flood inflow is 3,420 cfs; the routed test flood outflow of 3,150 cfs would overtop the low point in the left abutment by about 2.0 ft. The spillways can pass about 7 percent of the routed test flood outflow without overtopping the low point in the left abutment.
