Project Description
Savage Rapids Dam was a 39 foot high, 500 foot long diversion dam that spaned the mainstem of Oregon's Rogue River. The dam's fish ladders and screens did not meet current standards, and at times the dam completely blocked upstream fish passage. The dam negatively impacted adult spring Chinook salmon, which spawn exclusively upstream of the dam, and impeded passage for four other runs of salmon and steelhead. Slayden Construction Group was awarded a contract to remove the Savage Rapids Dam. RDG assisted Slayden Construction Group, Inc. with constructability issues, value engineering and design of temporary fish passage solutions during dam removal. RDG was involved and attended technical meetings with regulatory agencies and BOR personnel. Constructability focused on cofferdams, temporary dewatering facilities, and fish passage. RDG designed a retrofit to the south fish ladder that was implemented during dam removal to ensure fish passage through the project area.
