Navajo-Gallup Water Supply Project

The Navajo-Gallup Water Supply Project is a major infrastructure project that once constructed, will convey a reliable municipal and industrial water supply from the San Juan River to the eastern section of the Navajo Nation, southwestern portion of the Jicarilla Apache Nation, and the city of Gallup, New Mexico via about 300 miles of pipeline, at least nineteen pumping plants, and two water treatment plants.
These service areas currently rely on a rapidly depleting groundwater supply that is of poor quality and inadequate to meet the current and future demands of more than 43 Navajo chapters, the city of Gallup, and the Teepee Junction area of the Jicarilla Apache Nation. Ground water levels for the city of Gallup have dropped approximately 200 feet over the past 10 years and over 40 percent of Navajo Nation households rely on hauling water to meet their daily needs. Inadequate water supply also impacts the ability of the Jicarilla Apache people to live and work outside the reservation town of Dulce.
The Navajo-Gallup Water Supply Project will provide a long-term sustainable water supply to meet the future (40-year) population needs of approximately 250,000 people in the referenced communities through the annual delivery of 37,764 acre-feet of water from the San Juan Basin. The project's eastern branch (Cutter Lateral) will divert approximately 4,645 acre-feet of water via the Cutter Reservoir annually with no return flow to the San Juan River. The project's western branch (San Juan Lateral) will divert the remaining 33,119 acre-feet of water with an anticipated average annual return flow of 1,871 acre-feet.
In 2020, water deliveries to Navajo communities began on the Cutter Lateral. Deliveries to the Jicarilla Apache Nation from the Cutter Lateral began in 2022. Construction on the San Juan Lateral has been underway since 2012 and now has approximately 100 miles of transmission line pipe installed and 5 pumping plants either complete or under contract. Design and construction has also begun on the San Juan Lateral Water Treatment Plant. Water deliveries are expected to begin in 2028.

Authorization Background
The Navajo-Gallup Water Supply Project was authorized for construction by the Omnibus Public Land Management Act of 2009, Title X Part III (Public Law 111-11 on March 30, 2009) as a major component of the Navajo Nation San Juan River Basin Water Rights Settlement in New Mexico.
This act authorized the Secretary of the Interior, acting through the Commissioner of the Bureau of Reclamation to construct, operate, and maintain the Navajo-Gallup Water Supply Project in substantial accordance with the preferred alternative outlined in the Planning Report / Final Environmental Impact Statement.
The PR/FEIS was one of several prerequisites specified in the legislation that had to be completed prior to initiating construction of the project. In addition to completion of the PR/FEIS and associated record of decision, a water rights settlement agreement and settlement contract with the Navajo Nation had to be executed, as well as a cost-share agreement with the state of New Mexico and required repayment contracts with project beneficiaries.
Reclamation completed the PR/FEIS in July 2009 and the ROD was signed by the Secretary of the Interior on October 1, 2009, approving Reclamation's selection of the preferred alternative described in the PR/FEIS The Navajo San Juan Water Rights Settlement Agreement among the United States, Navajo Nation, and state of New Mexico was executed on December 17, 2010, and the Settlement Contract between Reclamation and the Navajo Nation was executed on the same date. These historic agreements represent a significant milestone in fulfilling long-outstanding water rights claims of the Navajo Nation while protecting existing water uses and providing for future growth within the amount of water apportioned to New Mexico by the Colorado River Compact.
Following the process stipulated in PL 111-11, the signatory parties to the Settlement (Navajo Nation, State of New Mexico and the United States via the Secretary of the Interior) agreed to extend the completion date of the Navajo Gallup Water Supply Project from December 2024 to December 2029 to analyze, acquire, and incorporate water storage and intake features from the San Juan Generating Station into the NGWSP that would provide substantial benefits to the project. Formal extension was issued by Secretary Deb Haaland on September 20, 2024.
Project Documents
- The Omnibus Public Land Management Act of 2009, Title X Part III (Public Law 111-11) signed on March 30, 2009, provided the authorization to construct this important project as a major component of the Navajo Nation San Juan River Basin Water Rights Settlement in New Mexico. The act requires that all project features are completed no later than December 31, 2024, unless the three signatory parties to the Settlement Agreement (the Navajo Nation, the State of New Mexico, and the Department of the Interior) agree to extend the completion date. On September 20, 2024, following mutual agreement between the signatory parties, the Project completion deadline was extended to December 31, 2029, by Secretary of the Interior Deb Haaland.

Navajo-Gallup Water Supply Project
The Navajo-Gallup Water Supply Project was authorized in 2009 through Public Law 111-11 to be constructed by the Bureau of Reclamation. The Project consists of two primary branches, the San Juan Lateral (west) and Cutter Lateral (east). Construction on the Project began in 2012 just north of the city of Gallup on Reach 12A of the San Juan Lateral. Construction on the San Juan Lateral continues and is expected to begin providing water to local communities in 2028. Construction of the Cutter Lateral was completed, and water deliveries began in 2020.
San Juan Lateral Construction

Construction activities have progressed steadily from the south, moving northward toward the San Juan River as Reclamation has completed the construction of over 100 miles of transmission pipeline and three pumping plants along U.S. Highway 491 from just north of Gallup, NM, to areas southeast of Shiprock, NM. Additional sections of pipelines and other pumping plants are under construction and more remain to be completed.

In 2023, Reclamation acquired an existing intake structure and reservoir previously associated with the San Juan Generating Station. The reservoir has since been renamed the Frank Chee Willetto Reservoir and will be used to store water for use through the San Juan Lateral. A new pumping plant at the intake will be constructed to convey water to the Frank Chee Willetto reservoir and then that water will be pumped to the San Juan Lateral Water Treatment Plant through an additional pumping plant on Reach 2. Modifications to the Frank Chee Willetto Reservoir are planned to increase functionality and reduce operational complexity.

Once treated, the water will be carried downstream to the thousands of homes in communities along U.S. 491, Shiprock, New Mexico, Crownpoint, New Mexico and the City of Gallup, NM. Connections to and distribution of treated water into communities from the San Juan Lateral and sublaterals will be completed by the Navajo Nation through the Navajo Tribal Utility Authority.

Construction of the sublateral to the community of Coyote Canyon (Reach 10.1.1) began in February 2025 and is expected to be completed in 2026. Construction of the sublateral extending to Crownpoint, NM, (Reaches 10.1 – 10.3) is expected to begin in 2026.

The Codetalker sublateral (Reaches 12.1 and 12.2) has been installed parallel to NM Route 260 from Yah-te-Hey Junction to the Arizona border. This sublateral will provide water to Window Rock, Arizona through a short section that remains to be completed.
Cutter Lateral Construction

Construction of the Cutter Lateral is complete except for Reach 24.1 Lybrook. Construction is anticipated to begin on that final section in early 2026.
