Recently there has been increased interest in roller compacted concrete (RCC) for use in dams. However, to date there has been very little practical experience in construction. Middle Fork Dam, constructed during the summer of 1984, is one of the few major RCC dams completed to date. This paper discusses the aspects of design related to construction and the actual construction of the dam itself. A brief history of the project is given, including the rationale behind sizing and dam type selection. Design called for maximizing the use of available on-site materials including the use of oil shale as concrete aggregate for the first time. Construction was facilitated by minimizing the impact of appurtenant project features on RCC placement.
