The office is responsible for Reclamation projects and program activities in the Upper Colorado, Gunnison, Yampa, White, Dolores, Uncompahgre, Animas, and San Juan river basins and works with the Ute Mountain Ute Tribe, Southern Ute Indian Tribe, Jicarilla Apache Nation, and Navajo Nation, as well as numerous water user organizations.
Reclamation continues Animas-La Plata Project contract negotiations with the Ute Mountain Ute Tribe
Contract negotiations continue on a proposed repayment contract for the Animas-La Plata Project with the Ute Mountain Ute Indian Tribe for the Tribe's statutory allocation of project water. The next virtual public meeting will be Monday, Nov.18 from 9-11 a.m.
The contract to be negotiated will provide for storage and delivery of project water and provisions for payment of operation and maintenance costs of the project. All negotiations are open to the public as observers, and the public will have the opportunity to ask questions and offer comments pertaining to the contract during a 30-minute comment period following the negotiation session.

Navajo Dam Road Closure and Drilling Update
As part of Reclamation's Safety of Dams Program, crews began exploratory drilling in Jan. 2024 to gather geotechnical data on Navajo Dam, located 45 miles east of Farmington, New Mexico. Under this program, Reclamation completes annual inspections and studies in order to identify potential issues that may lead to a corrective action. While all dams have seepage, there has been an increase in the amount of seepage at Navajo Dam over the years which has led to the need for the current exploratory work.
Reclamation wants to identify the source of the seepage and evaluate if new state-of-the-art practices that were unavailable at the time of construction would reduce the seepage.
"This exploratory drilling will give Reclamation the necessary information to learn how best to address the seepage issues at Navajo Dam," said Western Colorado Area Manager, Ed Warner.
On September 11, 2024, drilling crews are returning to Highway 539 and Highway 511 to continue drilling activities on the top of Navajo Dam. Highway 539 will be closed to public access, then Highway 511 will be reduced to a single travel lane while drilling takes place until May 2025.
"Drilling at Navajo Dam is time-intensive due to several factors including the sampling and testing process, complexities of drilling angled holes, onsite sample preservation, shipping preparation, and fighting external factors such as high winds, varying temperatures, and traffic control. Drilling is paused every 10-feet in holes that vary in depth from 120-feet to 450-feet to acquire samples and/or complete testing." said Reece Carpenter Resource Division Manager for the Western Colorado Area Office.
It is anticipated that drill crews will need to complete testing and data collection on 26 or more drill hole locations so that a thorough analysis can be achieved, and the seepage area identified. Due to the complexity of the exploratory drilling, it is expected that crews could be working for up to two years.
The drilling schedule and other project updates will be available on our Navajo Reservoir web page. Road closure information is also available on New Mexico's Department of Transportation website.
