Solutions to Spillway Tainter Gate Icing Problems
The Gavins Point Project on the Missouri River near Yankton, SD, includes an earth dam with two alternative methods for making releases, a hydroelectric power plant and a concrete spillway structure. The Gavins Point Project provides regulated releases into approximately 1305 Km (811 miles) of the Missouri River between Yankton, South Dakota and St. Louis, Missouri. By the early 1970's, it was realized that at least three tainter gates must always be available during the winter to make discharges if partial or complete powerhouse discharge capability is lost There are no flood control tunnels or bypass valves. The spillway at the Gavins Point Project has fourteen, 12.39 meters (40 feet) wide by 9.14 meters (30 feet) high, tainter gates. The spillway was designed for a discharge capacity of 16,537 cms (584,000 cfs). The original design included side seal heaters and an air bubbler system to keep the tainter gates free of ice. Tainter gate freezing problems have been encountered since the original closure of the dam in 1955. The capability to reliably make discharges during extremely cold weather is required to assure an adequate water supply and to minimize downstream ice problems. This paper discusses past, present, and feasible future alternatives to assure reliable operation of the tainter gates at the Gavins Point Project.
