The Corps of Engineers seeks proposals to design and construct a fish passage corridor through the partially built Elk Creek Dam project north of Medford, Ore. Bids are due Jan. 8, 2008.
The Corps' Portland District issued the solicitation Dec. 7. At one time, it had anticipated issuing the solicitation Oct. 31. (HNN 10/16/07)
The plan would require demolition of about 50,000 cubic yards of roller-compacted concrete and 15,000 cubic yards of conventional concrete. The cost of the work is expected to range from $10 million to $25 million.
Backed by initial funding from Congress, the Corps earlier this year said it would seek bids to remove a section of the dam to restore fish passage in Elk Creek.
Legal challenges halted construction of the dam in the 1970s, although Congress eventually appropriated funds to resume construction in fiscal year 1985. However, dam completion subsequently was halted by an injunction that the Corps chose not to contest further.
The Corps has operated a temporary �trap and haul� operation for fish at Elk Creek Dam for many years. By building a fish passage corridor, or notch, through the RCC dam, the Corps plans to return Elk Creek to its original alignment and gradient. The action also should reduce jeopardy to coho salmon, listed as threatened by the Endangered Species Act, and other native fish, it said.
While the Corps has no plans to complete construction of Elk Creek Dam, it also has said the fish passage work would not prevent future completion of the dam.
Proposals are due 4 p.m., Jan. 8, 2008.
