National Program for Inspection of Non-Federal Dams. McLeod Pond Dam (MA 00046), Connecticut River Basin, Colrain, Massachusetts. Phase I Inspection Report
The McLeod Pond Dam consists of a series of earthen dikes and two concrete structures. The concrete structures are the main and auxillary spillways, each of which is positioned between outcrops of ledge. The age of the dam is unknown. Based on the irregularity of the configuration of the dikes and the differences in the concrete structures, it appears that the dam was constructed over a period of years. The concrete structures are in good to fair condition. The embankments are in fair to poor condition. There are no obvious signs of failure or seepage conditions, especially at the dikes, and low freeboard present at the dikes warrant remedial treatment within a year. Based on the size and hazard classification in accordance with the Corps of Engineers Guidelines, the spillway test flood falls between a 50-year flood and a 100-year flood. Hydraulic analysis indicates that the spillway will not pass the test flood without overtopping the earth embankments. However, both the dam and pond are quite small and the potential hazard, in the event of a dam failure, is very low. Additional investigations of the seepage at the dikes, the structural stability of the dikes and spillways and the method of providing additional freeboard at the dikes are recommended.
