SUBJECT: Agenda Item 8e, September 24-25, 2001, Board Meeting-
Colorado River Basin Issues -
Discussion on Future Policy Regarding the Gallup Navajo Project in
New Mexico

Backl!round

The Navajo Nation, in cooperation with the U.S. Bureau of Reclamation and the
State of New Mexico, is in the process of developing the Gallup-Navajo Project. NEPA
compliance was started in January 2000 and a Record of Decision is anticipated in
February 2003. Federal legislation authorizing the project will likely be introduced in
January 2002.
The Gallup-Navajo Project would divert 37,764 AF\YR from the San Juan River
Basin for use on Indian lands in New Mexico and Arizona (see attached map). Of the
37,764 AF\YR diverted, it is estimated that 35,893 AF\YR would be consumptively used.
Of the 37,764 AF\YR, the City of Gallup would receive 7,500 AF\YR and the Jicarilla
Apaches would receive 1,200 AF\YR. The City of Gallup and some of the Navajo lands
in New Mexico are located in the Little Colorado River Basin, a Lower Basin tributary of
the Colorado River. Also, some of the Navajo lands served in New Mexico will be
located in the Rio Grande Basin. Navajo lands served in Arizona are all located in the
Little Colorado River Basin and would receive 6,411 AF\YR.
Pursuant to the Upper Colorado River Compact, the water apportioned to the
Upper Basin States is allocated as follows:

Arizona
Colorado
New Mexico
Utah
Wyoming

3,855,375

The current hydrologic determination of water available to the Upper Basin is only 6.0
MAF, significantly less than the 7.5 MAF apportioned under the Colorado River
Compact. Currently both New Mexico and Arizona have contractually obligated all the
water apportioned to them under the current hydrologic determination. New Mexico uses
at build out, with Gallup-Navajo, would be approximately 695,000 AF and Arizona's in
