Restoration Programs Advance

San Joaquin River Restoration Program

The San Joaquin River Restoration Program is a comprehensive, long-term effort to restore and maintain flows from the main stem of the San Joaquin River below Friant Dam to the confluence of the Merced River in Central California, in order to create naturally reproducing and self-sustaining populations of salmon and other fish in the river while reducing or avoiding adverse water supply impacts from restoration flows.

Federal participation in the program is mandated under the San Joaquin River Restoration Settlement Act, part of the Omnibus Public Land Management Act of 2009.

During 2013

Significant activities accomplished throughout 2013 kept momentum moving forward across many program areas that all contributed towards achieving the long-term goals. Information continued to be collected on major constraints to fish reintroduction in the river channel and on what actions need to be implemented prior to and during reintroduction of salmon.

Water Management Goal Accomplishments

Key accomplishments towards achieving the Water Management Goal include the following:

Flows Implementation Accomplishments

The fourth and final year of interim flows began on October 1, 2012, and concluded on December 31, 2013. Data collection continued, including water temperature, groundwater levels, sediment, water quality, dissolved oxygen and biological studies. Seepage management activities to support interim flows continued, including working with landowners to resolve seepage issues through easements or projects on their properties, as well as monitoring of shallow groundwater wells to address seepage concerns and expanding of the groundwater monitoring network on public and private property to better understand changes in shallow groundwater conditions. Key flow implementation accomplishments include the following:

Other key program documents released include the Final Fiscal Year 2013 Annual Work Plan and the Draft and Final Fiscal Year 2014 Annual Work Plan.

2014

During 2014, the program will work to accomplish the following key activities:

Looking Further Ahead

Key events in the following year will continue to mark significant program accomplishments. The last year of experimental, or interim, flows ended in 2013, and restoration flows begin January 2014. With obtaining flowage easements, once again, the river will be reconnected for the entire 153 mile stretch of the restoration area, and spring-run Chinook salmon will be released into the river in the spring.

The program will continue shallow groundwater monitoring and working with landowners to address potential seepage concerns related to restoration flows. As data is obtained, the program will account for subsidence, as necessary, for major projects. The Friant-Kern Canal Capacity Restoration Project is anticipated to be the first project to begin construction. One major channel improvement project will release draft environmental documents for public comment and could start construction in 2016/2017.

Battle Creek Salmon and Steelhead Restoration Project

During 2013, the Region advanced the Battle Creek Salmon and Steelhead Restoration Project, which is among the largest cold-water anadromous fish restoration projects in North America.

The project is an effort to increase threatened and endangered Chinook salmon and Central Valley steelhead trout populations by restoring about 48 miles of habitat -- 42 miles in Battle Creek and another six miles in its tributaries -- while maintaining renewable energy production at the Battle Creek Hydroelectric Project, owned and operated by the Pacific Gas and Electric Co.

Restoration was begun in 2010 and is scheduled for completion in 2016. It is being accomplished in three phases, primarily through the removal of five diversion dams, placement of screens and ladders on three other diversion dams, and increasing stream flows, all within Tehama and Shasta counties in northern California.

Phase 1A

With the removal of Wildcat Diversion Dam in 2010, about 15 miles of stream habitat was restored for Chinook salmon and Central Valley steelhead trout. The majority of fish screen and ladder construction was completed on the North Battle Creek Feeder and Eagle Canyon Diversion Dams in 2011; a contract to complete the NBCF access road (including cut-slope stabilization) was awarded in July 2013, and implementation of civil, mechanical and electrical design changes is expected to begin in Fiscal Year 2014. Upon full completion of the work at the NBCF and Eagle Canyon Diversion Dams sites in 2015, an additional nine miles of stream habitat will be restored.

In January 2013, a contract was awarded to construct a fish barrier weir and maintain a minimum flow of 5 cubic feet per second in Baldwin Creek near Asbury diversion, downstream of the Darrah Springs State Trout Hatchery. The 5 cfs will allow for suitable salmon and steelhead habitat, while the barrier will prevent these fish, which could carry viruses, from infecting the trout hatchery. This construction will restore an additional mile of habitat. Upon completion of Phase 1A, 25 miles of stream habitat will have been restored.

Phase 1B

Construction of the Inskip Powerhouse discharge outlet and a 5,600-foot bypass to Coleman Canal on the South Fork of Battle Creek (to prevent mixing of north and south fork waters) was completed in January 2013. Several improvements were performed by Reclamation construction crews in 2013, including access road drainage improvements and removal of sediment at the upper jump basin and within the canal. Safety and facility access improvements are planned for completion in 2014.

Phase 2

Data collection, as well as design and compliance efforts, occurred in 2013 for this final project phase, which involves the installation of a fish screen and ladder on Inskip Diversion Dam, installation of a South Powerhouse discharge outlet connector, and removal of Lower Ripley Creek Feeder, Soap Creek Feeder, and Coleman and South Diversion dams. Phase 2 construction is scheduled to occur from 2015 to 2016. Upon completion of Phase 2, 23 more miles of stream habitat will have been restored.

Project History

Via a Memorandum of Understanding, signed in June 1999, Reclamation, the National Marine Fisheries Service, U.S. Fish and Wildlife Service, the California Department of Fish and Wildlife and PG&E initiated work on the project. In addition to the MOU partners, the project has been developed in collaboration with various resource agencies, including the California Wildlife Conservation Board, with participation from the public, stakeholders, and landowners (including the Greater Battle Creek Watershed Working Group and the Battle Creek Watershed Conservancy).

The project is being supported with federal, state and private funding. The American Recovery and Reinvestment Act of 2009, the CALFED Bay-Delta Program, and the Iron Mountain Mine Trustee Council are contributing federal funds; the DFW, the WCB, the California Department of Transportation and the California Department of Water Resources are contributing state funds; and the Packard Foundation (via The Nature Conservancy) is contributing private funds. PG&E is contributing to the project in the form of foregone energy generation, voluntarily pursuing amendments to the Battle Creek Hydroelectric Project’s federal energy generation license, and transferring certain water rights to the DFW.

The restoration program includes flow management, channel rehabilitation, sediment control and watershed restoration. The results are monitored and assessed to incorporate experience into future restoration efforts through adaptive management.

The program differs from many other restoration programs in that it employs a riverine approach intended to create a dynamic river capable of building and maintaining anadromous fish habitat system-wide. The program’s goals are to create sufficient suitable habitat through achievement of healthy river attributes to maintain fish populations and to predict, measure and evaluate progress toward meeting long-term fishery and habitat goals that also influence short-term management actions.

Restoration of the river, below Trinity and Lewiston dams, is an important aspect of meeting requirements of the 1992 Central Valley Project Improvement Act for fish and wildlife protection and mitigation as the CVP meets its water supply responsibilities.

Since the signing of the TRRP Record of Decision in 2000, the restoration program has finished Phase 1 of the channel rehabilitation component of the ROD.

During 2013, the program completed two channel rehabilitation sites, Douglas City and Lorenz Gulch. To date, the program has completed 30 of the originally proposed 47 rehabilitation sites within the 40-mile restoration zone.

At the Lower Douglas City site downstream of the Highway 299 bridge at Douglas City, Reclamation, and program partners created a split flow channel and island, enhanced an existing gravel bar with large wood, placed boulders to create fish holding habitat, and enabled the Weaverville Community Service District to replace an infiltration gallery to increase withdrawals from the mainstem of the Trinity River. The infiltration gallery reduces withdrawals from the Weaver Creek tributary, important habitat for threatened coho salmon. The project was constructed on private, municipal and state property in cooperation with three local landowners, the CSD and the California Department of Transportation.

More extensive construction took place at the Lorenz Gulch site under oversight of the TRRP partner, the Yurok Tribal Fisheries Department, and in cooperation with the Bureau of Land Management. Construction of an in-river island, a side-channel, large wood-and-boulder habitat placements, and extensive native plant revegetation were coordinated to accommodate planned improvements to the BLM recreation area, including improved river access, parking, sanitation and camping.

In 2013, the TRRP also:

Central Valley Project Improvement Act

The Central Valley Project Improvement Act of 1992 amended previous authorizations of the CVP to include fish and wildlife protection, restoration, and mitigation as project purposes having equal priority with irrigation and domestic uses; and fish and wildlife enhancement as a project purpose equal to power generation.

From 1993 through 2013, Reclamation and its partners have completed several large projects, including the Glenn-Colusa Irrigation District fish screen, the Anderson-Cottonwood Irrigation District fish screen, the Shasta Lake Temperature Control Device, the Contra Costa Canal pumping plant, the Coleman National Fish Hatchery, and the Red Bluff Fish Passage Improvement Project. Mid-Pacific Region implementation of the CVPIA is currently comprised of more than 20 programs and projects that fall into broad resource areas, including fish, refuge water supply, habitat restoration, and ecosystem and water operations modeling. Reclamation and the U.S. Fish and Wildlife Service jointly implement the CVPIA.

Fish Resource Area

The goal for the Fish Resource Area is to double the natural production of anadromous fish in the Central Valley on a sustainable, long-term, basis. In addition to reservoir releases, Reclamation and Service restoration accomplishments in 2013 in the Sacramento Basin include:

Reclamation and Service restoration accomplishments in the San Joaquin Basin during 2013 include:

The Fish Resource Area includes a number of actions to assess and monitor the performance of restoration efforts and plan for undertaking the most effective future actions. The Fish Resource area made substantial investments in establishing a structured decision making framework for planning future fish restoration actions.

CVPIA funding related to the Fish Resource Area includes financial support for the San Joaquin River Restoration Program and the Trinity River Restoration Program.

Refuge Water Supply Resource Area

The goal of the Refuge Water Supply Resource Area is to provide water supply for optimal habitat management to 19 federal, state and private wildlife refuges. Water supplies are categorized as Level 2 (average historical deliveries obtained from project yield) and Incremental Level 4 (additional water required for optimum habitat obtained without involuntarily reallocations of project yeild). The Region was able to achieve the following deliveries through the Refuge Water Conveyance Component of the program during Fiscal Year 2013:

The Refuge Conveyance Program delivered 389,343 acre-feet of Level 2 water supplies, representing 92 percent the targeted 422,251 AF.

Habitat Restoration Program

The Habitat Restoration Program’s goals are to protect and restore terrestrial habitat and the species that depend on them.

The Habitat Restoration Program contributed to the protection of 1,030 acres of land through fee title acquisition of:

Of the acquired lands, 954 acres support the mitigation requirements for the State Water Resources Control Board.

Modeling Resource Area

The goal of the Ecosystem and Water Systems Operations Models Program is to develop broadly available and readily usable models and supporting data to evaluate the ecologic and hydrologic effects of existing and alternative operations of public and private water facilities and systems in the Sacramento, San Joaquin, and Trinity River watersheds. Accomplishments include: Modifications and improvements to the CalSim II cost for water operations; and improvements and modifications to the CalLite water operations model.

San Joaquin Valley Drainage Demonstration Plant

During 2013, the Region began constructing a demonstration plant that will be used to determine the best agricultural drain water treatment procedures for full-scale processing of irrigation drainage in portions of the western San Joaquin Valley.

Sladen Construction Group, Inc., of Stayton, Ore., was awarded $22.3 million to build the plant in the Panoche Drainage District, near Firebaugh, in Merced County.

Some of the world’s most productive agricultural lands are located in the San Joaquin Valley, but in the Central Valley Project’s San Luis Unit and adjacent lands a lack of full drainage service affects agriculture. Clay soils beneath farmland prevent irrigation water from percolating deeper into the soil and away from crop roots, causing water to accumulate in shallow water tables.

Better drainage will assist agriculture while avoiding or mitigating impacts to the environment and water quality. The irrigation drainage contains salt and elevated levels of a naturally occurring element, selenium.

The plant will be used to establish performance specifications for proposed selenium-removal technologies (reverse osmosis and bio-treatment); evaluate pretreatment options (flocculation, plate settler, media filtration, ultra-filtration, pH adjustment); and collect data for designs and cost estimates for future drainage plants in the CVP’s San Luis Unit.

The demonstration plant will be able to process 200 gallons per minute of agricultural drainage. The facility will include an 11,600-square-foot structure and 14 holding tanks of up to 65 feet in diameter and up to 26 feet in height.

The plant is scheduled to be operated for at least 18 months to collect data for final designs. Afterward, operation of the plant may continue by Reclamation or a designated operating partner.

Klamath Basin Achievements

During 2013, there were two significant accomplishments in the Klamath Project. In June 2013, federal agencies issued a biological opinion which concluded that ongoing operations of the project are not likely to jeopardize the continued existence of federally listed species. In December 2013, the Klamath Basin Task Force and Upper Basin Water Group announced an agreement in principle on Upper Basin water issues.

Biological Opinion

The BO issued by the National Marine Fisheries Service and the U.S. Fish and Wildlife Service analyzed effects of Klamath Project operations, through the year 2023, on federally listed species. The opinion found that Reclamation’s water management approach will optimize limited water supplies, benefitting both listed fish species and project water users.

The BO analyzed the effects of the ongoing operations of the project through March 2023 on federally listed, threatened and endangered species, including the endangered Lost River and shortnose suckers and the threatened coho salmon and their designated critical habitat.

Reclamation, NMFS, and the USFWS participated in extensive interagency coordination during 2012 and 2013 for the purpose of collaboratively developing a water management approach that has the flexibility to optimize the benefits of available water for federally listed species, while providing irrigation deliveries to the project. Through this collaboration, Reclamation developed an innovative approach, with the benefit of providing greater certainty, early in the year, on the amount of water that will be available for Upper Klamath Lake (endangered suckers), the Klamath River (threatened coho salmon) and the overall project.

Implementation of this innovative water management approach will be beneficial during dry hydrologic years such as 2013, and throughout the term of the BO, because the approach is expected to more efficiently optimize limited water supplies to benefit listed fish species and project water users than in the past.

Agreement in Principle

In December, Reclamation and other members of the Klamath Basin Task Force and Upper Basin Water Group announced an agreement in principle on Upper Basin water issues.

Task force members, which included representatives of the upper Klamath Basin agricultural community and the Klamath Tribes, and state and federal agencies, developed an agreement in principle on water that addresses continuing conflicts over water use in the upper basin. The agreement, which also addresses ways to improve the economic condition of the Klamath Tribes, was developed by a sub-group of the full task force.
The full Klamath Basin Task Force held its final meeting in December 2013 to review the agreement in principle on water, as well as proposals to reduce the federal costs of the Klamath agreements and ways to provide affordable power for irrigators. Following input from community members in 2014, an agreement in principle will be forwarded as recommended legislation to members of Congress.

Red Bluff Fish Passage Improvements/Pumping Plant

Reclamation is nearing completion of the $185 million Red Bluff Fish Passage Improvement Project in Red Bluff in northern California, a project that represents the culmination of decades of efforts by various entities to find a balanced solution that improves fish passage and the reliability of irrigation water to highly productive farmland.

The Region, which completed a new pumping plant and other major aspects of the project from 2010 through 2012, awarded a $3.9 million contract in September 2013 to decommission the Red Bluff Diversion Dam. Crews will work through 2014 to finish bracing the dam’s gates in the fully raised position.

During 2013, workers also restored the areas that were affected by construction. Earth moved during construction was returned to its natural shape and vegetation was planted to return the region to its former condition.

The overall improvement was required by the Central Valley Project Improvement Act of 1992 and reaffirmed by the National Marine Fisheries Service’s 2009 Biological Opinion for operation of the Central Valley Project, mandating an alternative to the Red Bluff Diversion Dam and raising of the gates year-round.

The Red Bluff Diversion Dam, completed in 1964, contains a series of 11 gates that, when lowered, provided for gravity diversion of irrigation water from the Sacramento River into the Tehama-Colusa and Corning canals. The Red Bluff Diversion Dam had been an impediment to upstream and downstream fish migration, and a significant portion of the Sacramento River spawning habitat for endangered salmon and steelhead upstream of the dam. Adult fish moving upstream had difficulty finding and using the ladders for passage over the dam, and juveniles migrating downstream through the dam became disoriented by the turbulence, resulting in significant mortality from predator fish. The main species of concern were the winter- and spring-run Chinook salmon, Central Valley steelhead and green sturgeon.

The fish passage improvement project involved construction of a pumping plant, screened to protect fish, which conveys water from the Sacramento River to the irrigation canals. The pumping plant has replaced the diversion dam. The dam’s gates have been placed in the open position for free migration of fish, and the braces will make the action permanent.

The new pumping plant ensures continued water deliveries to 150,000 acres of farmland throughout a four-county area, served by 17 water districts. The $185 million in funding for the project includes $113 million from the 2009 American Recovery and Reinvestment Act, the largest single outlay of ARRA funding in the nation by the Department of the Interior.

The project included construction of components such as the pumping plant intake; the pumping plant itself, which included nine pumps that together have a pumping capacity of 2,000 cubic feet per second; an 1,118-foot-long fish screen structure; a canal siphon; a discharge conduit; and a 660-foot-long bridge that allows maintenance workers access to the project.
