All work associated with removal of the first of four hydroelectric dams slated for demolition on the Klamath River in California and Oregon has been completed by contractor Kiewit, said dam owner Klamath River Renewal Corp. earlier this month.

Washington state is weighing controversial proposal to breach four lower dams to boost recovery of threatened salmon populations, with potential cost in billions to replace their power generation.

Four Snake River dams produce energy, enable commodity barging and provide reservoirs for irrigation.

A concept floated by Republican Mike Simpson, a U.S. congressman from Idaho, holds the potential to loosen the intractable logjam that has persisted for years among lawmakers, community members and federal officials to find a way to save the dwindling salmon population in the Columbia River Basin before it is too late.

California and Oregon now are dam co-licensees for estimated $450M Klamath River project to resolve federal concerns, but major work by contractor Kiewit is pushed back one year.

Contractor will develop GMP for the largest-ever such removal in the U.S., now estimated at $400 million.
