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.
