Rio Grande and Low Flow Conveyance Channel Between San Acacia Diversion Dam, NM, and the Narrows of Elephant Butte Reservoir, NM

AGENCY:

Bureau of Reclamation, Interior.

ACTION:

Notice of availability and notice of public hearings for the Draft Eenvironmental Impact Statement on the Rio Grande and Low Flow Conveyance Channel Modifications.

SUMMARY:

Pursuant to the National Environmental Policy Act (NEPA) of 1969 (as amended), the Department of the Interior, Bureau of Reclamation (Reclamation), has prepared a Draft Environmental Impact Statement (DEIS) on modifications to the Rio Grande and Low Flow Conveyance Channel system. The proposed modifications are located downstream from San Marcial, New Mexico.

The purpose of the DEIS is to analyze the environmental impacts of the proposed modifications to the main channel of the Rio Grande and Low Flow Conveyance Channel system. The proposed channel system realignment would allow for efficient conveyance of water to Elephant Butte Reservoir, effective valley drainage, and effective sediment management. The proposed changes would also promote the protection and restoration of the riparian and riverine ecosystem in the project area.

The DEIS describes and analyzes the impacts of two alternatives that would realign the Low Flow Conveyance Channel and Rio Grande system to the west side of the Middle Rio Grande Valley. Other alternatives included are the No Action and Discontinue Maintenance Alternatives. The project, as proposed, would be implemented in phases over the next 4 to 11 years, depending upon flow conditions, sediment deposition, and other factors. An adaptive management process would be used to provide a structured but flexible management approach to the construction and maintenance of the realigned channel system.

DATES:

A 60-day public review period commences with the publication of this notice. Written comments on the DEIS are due by November 7, 2000, and should be submitted to Mr. Art Coykendall at the address given below.

SUPPLEMENTARY INFORMATION:

The Flood Control Acts of 1948 and 1950 authorize Reclamation to construct and maintain channel works on the Rio Grande between Velarde, New Mexico, and Caballo Reservoir. These works promote the efficient conveyance of water to Elephant Butte Reservoir. Channel works also assist in meeting water delivery obligations required by interstate compact and international treaty. They also assist in providing reliable valley drainage and contribute to the safe passage of flood waters. To ensure that these project purposes continue to be met effectively, Reclamation has proposed to modify the main channel of the Rio Grande and Low Flow Conveyance Channel system.

Factors prompting a reevaluation of the channel system include changes in the flow of the Rio Grande due to climatic variation and infrastructure changes. Chronic sediment management problems, anticipated reductions in federal funding, and new legal constraints on system operations, such as the Endangered Species Act, are also factors prompting this reevaluation.

Purpose and Need for Action

The purposes of the proposed federal action are to convey water to Elephant Butte Reservoir, maintain effective valley drainage, manage sediment, and protect and promote restoration of the riparian and riverine system to help meet the following needs:

• Fulfill obligations to deliver water to Mexico and as required under interstate water compact;
• Sustain agricultural production;
• Maintain high flow capacity in the river;
• Manage costs of system operation and maintenance; and
• Restore native species habitat.

Hearing Process Information

Oral comments at the hearings will be limited to 10 minutes. The hearing officer may allow any speaker to provide additional oral comments after all persons wishing to comment have been heard. All comments will be formally recorded. Speakers not present when called will lose their privilege in the scheduled order and will be recalled at the end of the scheduled speakers.
