National Program for Inspection of Non-Federal Dams. Lower Lisbon Dam (NH 00144), Connecticut River Basin, Lisbon, New Hampshire. Phase I Inspection Report
The Lower Lisbon Dam is a 300-ft. long, 24 ft. run-of-the-river, solid concrete gravity dam set on an irregular bedrock foundation. The dam is presently not being used with the possible exception of ice jam control during the spring run-off period. The drainage area for the dam is 288 square miles and the normal impoundment is 96 acre-ft. It is small in size with a low hazard potential. The dam is judged to be in good condition. However, some features could not be observed because of water flowing over the overflow section of the dam. There is some spalling of concrete at the waste gate end of the downstream face of the overflow.
