Pueblo Dam, the first massive-head buttress dam in Bureau of Reclamation history, is nearing completion. Pueblo Dam is a feature of the Fryingpan-Arkansas Project in Colorado. The 23 buttresses of the dam are up to 180 feet high, among the highest of their type in the world. The buttresses form the dam's 1750-foot-long central section which is flanked by earthfill embankments. The buttress-embankment design is the most economical for the wide, gently sloping damsite. Hydraulic model studies aided in design of the ogee spillway, outlet works, and spillway stilling basin. Dam construction was divided into two contracts: the first included river diversion, excavation, and grouting; the second contract was for completion of the dam.
