Project Description
The design-build team of Slayden Construction Group, Inc. (SCG), River Design Group, Inc. (RDG) and HDR, Inc. was retained by Jackson County Roads and Parks to perform environmental studies, dam removal design and permitting, and deconstruction of the Gold Ray Dam. The existing concrete dam was built in 1941 and consists of a 38 foot high concrete structure spanning 360 feet across the Rogue River and included a powerhouse with ancillary structures.

RDG was responsible for project management of the design-build process including coordination of public meetings, facilitating permits, and development of construction phasing with the contractor. RDG was on-site during all the phases of construction to ensure fish passage and salvage actions are undertaken according to approved plans. In addition to removal of the dam and powerhouse structures, a restoration plan was implemented for Bear Creek, a major tributary to the Rogue River in the reservoir area. As a result of lowering the reservoir and restoring flow to natural conditions, the Bear Creek confluence required reconstruction to ensure fish passage. The entire project was completed within budget and on schedule in a paramount undertaking to open the Rogue River for 157 miles of unhindered fish passage.

The Gold Ray Dam was removed in 2010 by Jackson County. The design-build team of Slayden Construction Group, River Design Group, and HDR spearheaded the dam removal project. Scott Wright, P.E. (RDG), Darren Funk (SCG), and John Vial (Jackson County) served as the project managers to implement this monumental dam removal that freed over 157 miles of main stem Rogue River for fish passage.
