Lessons Learned from Elk Creek Damby Dennis R. Hopman, US Army Corps of Engineers, Portland, United States,
Abstract: This is the third of a series of papers published on the design and construction of Elk Creek Dam. The first paper discussed design and construction concepts to provide water tightness and assure a low rate of seepage through Elk Creek Dam. The second paper discussed techniques used during early construction to control cracking, prevent seepage, and provide void free concrete. This paper discusses and evaluates the success of design and construction objectives, provides lessons learned during construction, provides a summary of construction activities, and provides probable design changes that will be used when construction activities resume. It also discusses environmental considerations which halted construction in 1987 and recent developments dealing with legal and environmental concerns.
