The Bureau of Reclamation has extended the deadline for bids to construct spillways and canal headworks to rehabilitate 27.7-MW Minidoka Dam on the Snake River in Idaho. Bids now are due June 15.
Reclamation previously called for bids for the work by May 4. It issued a record of decision in September 2010 calling for replacement of a spillway and canal headworks cited in an environmental impact statement for Minidoka Dam. Minidoka is an 86-foot-tall zoned earthfill structure that began operating in 1909.
The agency said concrete of the 2,237-foot-long wood and concrete spillway, stoplog structure piers, and canal headworks has deteriorated to the point where it could fail soon. In addition, the headworks for the canals that run on the north and south sides of the dam show visible signs of deterioration.
A proposal to raise the height of the dam five feet is on hold. The Idaho Legislature is funding studies of enlarging the dam to secure more reservoir storage.
Reclamation currently seeks a contractor to furnish and construct a new south gated spillway, north and south roller-compacted-concrete dikes, north and south side canal headworks, and north and south RCC overflow spillways. Work also includes modifications to the existing north gated spillway. The work is valued at between $10 million and $25 million.
