Abstract:

The Souhegan River Watershed Dam No. 10A is located on Mill Brook approximately one mile upstream of Davisville, N.H. The dam is an earth embankment 951 feet long and 59 feet high with a drop inlet service spillway structure and a 30 inch outlet conduit. An earth emergency spillway 220 feet wide is cut into the left abutment. An earth emergency spillway 110 feet wide is cut into the right abutment. The dam is intermediate in size with a high hazard potential. The dam is in good condition at the present time. It is recommended that the owner retain the services of a registered professional engineer to investigate the cracking and erosion of the outlet conduit.
