SUPPLEMENTARY INFORMATION:

Construction of the Trinity River Division (TRD) of the Central Valley Project (CVP) was completed in 1963. The primary function of the TRD is to store Trinity River water for regulated diversion to the Central Valley of California for agricultural, municipal, and industrial uses. Construction and operation of the TRD resulted in the diversion of up to 90 percent of the average annual discharge in the Trinity River at Lewiston, and blocked access to 109 miles of salmon and steelhead spawning and rearing habitat. Reduced river flows, combined with excessive watershed erosion and encroachment of the river channel by riparian vegetation, caused major changes in the channel morphology resulting in the simplification and degradation of the remaining salmon and steelhead habitat of the Trinity River below the Lewiston Dam. This, in turn, resulted in rapid declines of salmon and steelhead populations following completion of the TRD.

In response to declining fisheries and degraded habitat conditions, the Secretary of the Interior (Secretary) decided in 1981 to increase flows in the Trinity River ranging from 140,000 acre-feet to 340,000 acre-feet annually, with reductions in dry and critically dry years. In addition, the Fish and Wildlife Service was directed to undertake a Flow Evaluation Study to assess fish habitat at various flows, summarize the effectiveness of other instream and watershed restoration activities, and recommend appropriate flows and other measures necessary to better maintain favorable habitat conditions. The Flow Evaluation Study began in October 1984 and was completed in June 1999. In October 1984, the Trinity River Basin Fish and Wildlife Management Act (Management Act) (Public Law 98-541) was enacted by Congress with the goal of restoring fish and wildlife populations to pre-TRD levels. The Act provided funding for construction, operation, and maintenance of the 11-item action plan developed by the Trinity River Task Force in 1982.

In 1992, the Central Valley Project Improvement Act (CVPIA) (Public Law 102-575) was passed. Section 3406(b)(23) of the CVPIA provides, through the TRD, an instream release of not less than 340,000 acre-feet of water into the Trinity River to meet Federal trust responsibilities to protect fishery resources of the Hoopa Valley Tribe and to meet the fishery restoration goals of the Management Act. The recommendations for mainstem Trinity River fishery restoration will be developed after appropriate consultations with Federal, State, Tribal, local agencies, and affected interests, and after completion the Flow Evaluation Study.

To restore the natural production of anadromous fish in the Trinity River in accordance with the 1981 Secretarial Decision, the Management Act, and the CVPIA, the FEIS/EIR analyzes the impacts of:

(1) Increased instream releases into the Trinity River to provide anadromous fish habitat and restore fluvial processes,

(2) Implementation of a channel rehabilitation program,

(3) Implementation of a spawning gravel supplementation program,

(4) Implementation of a watershed rehabilitation program, and

(5) Implementation of an Adaptive Environmental Assessment and Management Program.

On October 19, 1999, the Service published a notice in the Federal Register announcing the availability of the draft EIS/EIR and the commencement of the public comment period in the Federal Register (64 FR 56364). The comment period was originally scheduled to end on December 8, 1999. However, on December 2, 1999 the Service extended the period until December 20, 1999 (64 FR 67584). On December 27, 1999 the Service published a notice in the Federal Register , which reopened the public comment period until January 20, 2000 (64 FR 72357). In total, the lead agencies received written comments from 6445 people and organizations (1009 letters and 5436 preprinted postcards). The primary concerns expressed in many of the comments related to fishery resource analyses, power generation impacts analyses, mechanical modifications to riverine habitat and the amount of river flow proposed for restoration efforts. A list of the commenters and the response of the agencies to the comments is presented in the FEIS/EIR.

The FEIS/EIR is intended to accomplish the following:

(1) Inform the public of the proposed action and alternatives;

(2) Address public comments received during the scoping and comment periods;

(3) Disclose the direct, indirect, and cumulative environmental effects of the proposed action and each of the alternatives; and

(4) Indicate any irreversible commitment of resources that would result from implementation of the proposed action.

This notice is provided pursuant to Section 102(2)(c) of the National Environmental Policy Act of 1969, as implemented by the Council on Environmental Quality regulations (40 CFR parts 15001508), and the California Environmental Quality Act of 1970, as amended.

The Technical Appendixes (TA) for this FEIS/EIR will be made available upon request from the U.S. Fish and Wildlife Service, Arcata Office, 1655 Heindon Road, Arcata, CA 95521; (707) 822-7201.
