摘要

Bernhart Dam is an earth embankment with a masonry brick core wall. A 5-foot high masonry wall is located at the upstream edge of the top of the dam. The embankment is approximately 180 feet in length and has a maximum height of 30 feet. The side slopes are 2 horizontal to 1 vertical (2H:1V) upstream and 3H:1V downstream. The top of dam width varies between 22 and 35 feet. The dam impounds a reservoir with a normal pool storage capacity of 129 acre-feet. The reservoir was originally used for water supply but now serves only recreational purposes. A broad-crested spillway with a 40-foot crest length is located at the right abutment. The crest is at Elevation 395, 5 feet below the top of the dam. A masonry sidewall is provided along the left side of the spillway. The right sidewall of the spillway is formed by the nearly vertical rock abutment. The outlet channel is provided with masonry training walls along both sides for an approximate distance of 300 feet downstream.
