National Program for Inspection of Non-Federal Dams. Leaping Well Reservoir (MA 00586) Connecticut River Basin, South Hadley, Massachusetts. Phase 1 Inspection Report
Leaping Well Reservoir Dam is an L-shaped, 480-foot long earthfill embankment containing an inclined brick masonry membrane about 2-feet below the surface of upstream slope. Normal outflow from the reservoir occurs through a 12-inch gated pressure conduit. The following deficiencies were observed at the site: four non-functioning gates within the gatehouse; deterioration of the brick masonry foundation of the gatehouse; poor condition of the access footbridge to the gatehouse; presence of root growth along the dam; minor erosion of the downstream face of the east embankment; and the presence of a 12-inch pressure conduit through embankment. Generally, the dam is in fair condition. Hydraulic analyses indicate that the test flood would result in a peak inflow of 580 cfs, a peak outflow of 470 cfs, and that the conventional outlets can discharge 3% of the test flood outflow. The recommended test flood would result in a maximum water surface elevation of 216.3, which represents an overtopping of the dam by 0.3 feet.
