National Dam Inspection Program. Lake Sabula Dam (NDI ID Number: PA-425 DER ID Number: 17-10), Ohio River Basin, Sandy Lick Creek, Clearfield County, Pennsylvania. Phase I Inspection Report.

摘要

Lake Sabula Dam consists of an earth embankment approximately 600 feet long with a maximum height of 22 feet from the highest elevation on the crest of the dam measured to the downstream invert of the outlet conduit. The crest width of the dam varies between 20 and 26 feet. The flood discharge facilities for the dam consist of a primary spillway combined with the outlet works and an open channel emergency spillway. Both the primary spillway and the emergency spillway structures are located at the center of the embankment. The primary spillway structures consist of an intake tower located on the upstream side of the crest which drains through two 24-inch cast-iron pipes into the reinforced concrete outlet conduit. The upstream end of the intake tower is equipped with stop logs, which permit adjusting the normal pool level of the reservoir. The emergency spillway is located to the left of the primary spillway and consists of a 20-foot-wide, 2-1/2-foot deep rectangular concrete channel which discharges into the outlet works discharge channel. The reservoir can be drained by the removal of stop logs from the primary spillway intake structure. (Author)
