Project Description
Gold Hill Dam was a 3 foot to 14 foot high concrete diversion dam on the mainstem of Oregon's Rogue River. The dam was 900 feet long and was historically used to provide water to power the Ideal Concrete Company’s facility near the City of Gold Hill. The city later used the diversion canal to supply municipal water. The dam did not have adequate fish passage facilities and was no longer being used as a water diversion with the construction of a water intake facility upstream of Gold Hill Dam by the City of Gold Hill. A fish passage analysis completed by the U.S. Bureau of Reclamation in 2000, recommended removing the dam to allow unhindered fish passage. River Design Group, Inc. and Slayden Construction Group proposed a joint venture to remove the dam and were awarded a $1.2 million contract for permitting and dam removal. RDG was the project manager and engineer of record for design and construction services. RDG and Slayden collaborated to remove the dam in July and August, 2008. the project was selected as the 2008 Special Project of the Year by the Oregon Chapter of American Public Works Association.

Multiple track hoes were required to remove the Gold Hill Dam in an efficient manner and minimize in-water work on the Rogue River. The dam was removed ahead of schedule and on budget.
