The Bureau of Reclamation awarded a $1,756,850 contract last Thursday to Northbank Civil and Marine, LLC, a small business from Vancouver, Washington, to construct fish ladder modifications to the Oak Street Diversion Dam located approximately 1 mile north of Ashland on Bear Creek.
When complete, the current fish ladder will be replaced with a new one on the opposite side of the dam. This is to satisfy requirements of improved fish passage and flow control. The primary features of the work will be demolition, earthwork, concrete, electrical and mechanical work to support operation of the new gates for controlling water releases. Work will be performed between June 15 and October 15, 2015, when flows are lower due to irrigation.
“The existing structure has shown to have some functionality issues that needed addressing,” says Douglas DeFlitch, Reclamation’s Bend Field Office Manager. “This work will greatly improve fish passage for ESA listed Coho Salmon, at the same time maintaining water supply for the Talent Irrigation District.”
Northbank Civil and Marine says the primary focus of the company is on marine, heavy civil and industrial construction.
This work is within Reclamation’s Rogue River Project area, which has 7 reservoirs, 16 diversion dams, 1 power plant, and more than 450 miles of canals serving Talent, Medford, and Rogue River Valley Irrigation Districts.
