A landslide of major proportions occurred during construction of Silver Jack Dam in western Colorado. This slide required relocation and redesign of the spillway conduit and basin. Hydraulic model studies were required to develop a satisfactory stilling basin. Although the contractor was engaged in constructing the spillway at that time, this redesign was accomplished without a major interruption in the work on the project.
