Box Canyon Dam Upstream Fish Passage Project

Fall of 2017

Box Canyon Dam, located on the Pend Oreille River in Washington, is required to provide upstream fish passage for the Bull Trout, West slope Cutthroat, and the Mountain Whitefish. AUS provided diving support for the project working for the General contractor, J.W. Fowler, and the cofferdam subcontractor, Pacific Pile and Marine. Multiple dive crews were utilized for rock removal, sheet pile burning, installation of a steel dewatering structure, and underwater concrete placement.
