Cle Elum Dam

Scope

Michels was selected as the foundation contractor to design and build the earth retention system for a 20-foot wide fish passage structure for the Cle Elum Dam. When the dam was built in 1933, the construction of fish passages were not included, resulting in the decline of a diverse habitat. The new structure is expected to benefit several species of fish.

The project included the installation of 102 880mm fully cased soldier piles to depths ranging from 35 to 95 feet, 222 tiebacks at an average depth of 70 feet, and 31,000 square feet of shotcrete lagging. Due to the steep slope, the project was divided into 6 different benches to provide level pads for the drill and crane to work.
