US ARMY CORP OF ENGINEERS NEWS RELEASE
July 7, 2011 is scheduled for diversion through regulating tunnels to allow for routine inspection of spillway slabs at Ft. Randall Dam (dam upstream from Gavins Point)
Pickstown, S.D. —The U.S. Army Corps of Engineers invites the public to witness the diversion of surplus water out of Fort Randall Dam through the dam’s four regulating tunnels July 7, between 10 a.m. and 2 p.m.
“This is only the second time in history that such a high volume of water will be released through the regulating tunnels,” said Tom Curran, Fort Randall Dam operations manager.
The opening of the regulating tunnels will equate to a flow of approximately 120,000 cubic feet per second (cfs) through these 22-foot diameter pipes. The water will be diverted to allow for routine inspection of the spillway slab at the dam. The spillway slab is 40 acres of concrete with a thickness of 2 – 6 feet, used to carry water downstream and away from the spillway gates.
Members of the public are invited to witness this event and will be allowed special access to a viewing platform immediately adjacent to the outlet area. Cameras will be permitted.
