Abstract:
Deadwood Dam, a feature of the Bureau of Reclamation's Boise Project, islocated on the Deadwood River 90 miles from Boise, Idaho. The dam is a concretearch-type structure with a structural height of 165 ft and a hydraulic height of 137 ft. Over 50 years of service in the harsh Idaho climate has resulted infreeze thaw deterioration, cracking, carbonation, and weathering over much of the dam's surfaces. In 1980, the Boise Regional Office requested that Reclamation's Denver Research Laboratories design and conduct a series of trial field repairs at Deadwood Dam. The results of these trials would be used to prepare repair construction specifications for rehabilitation of the dam.
