摘要

The Lower Hereford Manor Dam consists of an earth embankment approximately 1000 feet long with a maximum height of 37 feet from the downstream toe and a crest width of about 25 feet. The flood discharge facilities for the dam consist of a combined primary and emergency spillway located on the right abutment (looking downstream). The spillway is a rectangular concrete channel 17 feet wide, equipped with flashboards and a fish screen. The tops of the flashboards are at a level about two feet below the low spot on the embankment crest. The spillway discharge channel is a trapezoidal earth channel excavated across the drainage divide on the right abutment and discharging into Buck Run. The dam has no low-level outlet. The dam is located approximately 1-1/2 miles northeast of Zelienople along State Route 288 in Franklin Township, Beaver County, Pennsylvania.
