The RBDD was completed in the mid-1960s. When the
operable gates were lowered, the dam raised the surface
level of the Sacramento River, enabling gravity diversion
into the canals. Fish ladders constructed to allow passage
during dam operation were unreliable and inefficient. As
a result, the RBDD was a significant impediment to adult
and juvenile fish migration. The main species of concern
are winter-and spring-run Chinook salmon, Central
Valley steelhead, and green sturgeon.
After the decline of winter-run Chinook salmon, the
duration of annual gate operations began to steadily
decrease from twelve months to two months. When the
dam gates were raised, the Tehama-Colusa Canal Authority
continued to deliver irrigation water through a series of
short-term fixes, including a Temporary Pumping Plant,
a Research Pumping Plant, seasonal pumps, and Stony
Creek. The diversion capacity from these sources was not
enough to meet year-round irrigation demand.

Overview of Fish Screen and Forebay Construction (November 2011)
T h e S o l u t i o nThe Fish Passage Improvement Project is the culmination
of over 40 years of efforts by various entities to find
a balanced solution that improves fish passage and
reliability of irrigation water deliveries. Highlights of the
project include:
• Selection of a Project: The selected project included
the construction of a pumping plant near the
existing canal headworks with an initial installed
capacity of 2,000 cfs and a footprint that will allow
expansion to 2,500 cfs.
• Completion of Environmental Review: TCCA
certified the Environmental Impact Report under
the California Environmental Quality Act (CEQA)
on June 4, 2008, and Reclamation signed the Record
of Decision under the National Environmental
Policy Act (NEPA) on July 16, 2008.
• Construction: Construction commenced in spring
2010. The groundbreaking event included, among
others, Secretary of Interior Ken Salazar and former
Governor Arnold Schwarzenegger.
• Operation: The project was completed on schedule
and under budget. The new facility was substantially
complete and began delivering water in May 2012.
Full operation began in summer 2012.
The project received wide-spread support, including letters from the following:• SenatorDianneFeinstein,• SenatorBarbaraBoxer,• CongressmanWallyHerger,• CongressmanMikeThompson,• CongressmanDanLungren,• CongressmanGeorgeMiller,• PacificCoastFederationofFisherman’sAssociations,• CaliforniaTrout,• NaturalResourcesDefenseCouncil,• MetropolitanWaterDistrictofSouthernCalifornia,• StateWaterContractors,• Tehama, Glenn, Colusa, Yolo County Farm Bureaus, and • Tehama, Glenn, Colusa, Yolo County Boards of Supervisors.

H a b i t a t M i t i g a t i o nMitigation was required to compensate for unavoidable impacts to wetland and riparian habitats during construction of the fish screen and pumping plant. The mitigation site was selected and designed based on natural side channel habitats on nearby reaches of the Sacramento River. Side channel habitats are important because they increase instream and riparian habitat diversity by providing shaded cover and rearing areas for juvenile fish. Healthy rearing habitat may lead to higher juvenile growth rates, which in turn may improve juvenile fish survival. This is important for sensitive species, notably winter- and spring-run Chinook salmon, Central Valley steelhead, and green sturgeon.
The mitigation includes restoration of 32 acres of native, riparian habitat. Key features include an open-water channel and four native vegetation communities. The open-water channel is designed to maintain year-round connectivity to the Sacramento River. The native vegetation communities include emergent marsh, floodplain herbaceous, willow-riparian scrub, and mixed-riparian forest. Over time, these new communities will mature and connect with the existing habitat along the edges of the site.
The mitigation site is located directly across the river from the Red Bluff Pumping Plant in East Sand Slough (see Site Plan on page 3). Construction of the site commenced in 2012 and it is on-schedule to be complete in 2013.

Project Background: Red Bluff Diversion Dam
was completed in 1964 as a part of the Sacramento
Canals Unit of the Central Valley Project (CVP).
The fish passage problem at RBDD was addressed
in the Central Valley Project Improvement Act of
1992 - Public Law 102-575, Title 32 (CVPIA).
Specifically, Section 3406(b)(10) authorizes and
directs the Secretary of the Interior to develop
and implement measures to minimize fish passage
problems for adult and juvenile anadromous fish
at the Red Bluff Diversion Dam. The Fish Passage
Improvement Project at the Red Bluff Diversion
Dam was developed to respond to this federal
directive. The RBDD is owned by the U.S. Bureau
of Reclamation and operated and maintained
by the TCCA.Overview of Construction at the Mitigation Site (June 2012)
