Reclamation awards contract for Red Bluff Diversion Dam removal

The U.S. Bureau of Reclamation has awarded a US$3.28 million contract to E.C. Smith Inc. to decommission the Red Bluff Diversion Dam on California’s Sacramento River.

Reclamation most recently called for bids in July.

Per the contract, E.C Smith Inc. will demolish Red Bluff Diversion Dam’s interim pumping facility, a research pumping plant, a temporary pumping plant, settling basin drum screens, and Tehama Colusa Canal Check drum screens.

Work also includes decommissioning of the dam and two concrete fish ladders, removal of steel sheet piles, fabrication of stoplogs and lifting beam for a siphon outlet, and construction of a concrete cutoff wall to separate the stilling basin from the river.

The Red Bluff Diversion Dam Fish Passage Improvement Project began in 2010 with the construction of an interim screened pumping plant to deliver irrigation water while Red Bluff Diversion Dam’s gates were raised to provide passage for threatened and endangered salmon, steelhead and green sturgeon. That was followed by construction of a 1,118-foot-long fish screen, a permanent pumping station, and an electrical switchyard.

The current work is part of a $2.9 million allocation made by Reclamation in its fiscal year 2013 budget for final work on the Red Bluff Pumping Plant and Fish Screen.
