Tribal Water Study: An Overview

The purpose of this policy brief is to provide an overview of the Colorado River Basin Ten Tribes Partnership Tribal Water Study (Study), a unique review of the water rights, water uses, and future plans of the member tribes of the Colorado River Basin Tribes Partnership (Ten Tribes Partnership). The information in this policy brief is taken directly from the Study.

In the foreword to the Study, Bureau of Reclamation (Reclamation) Commissioner Brenda Burman states that Reclamation and the Ten Tribes Partnership collaborated to document current water use and potential future water development to better facilitate planning and decision-making throughout the Colorado River Basin (Basin). The Study strengthens a Department of the Interior commitment to address water issues facing tribes and recognizes that the Colorado River is an essential foundation for the physical, economic, and cultural sustenance of tribes in the Basin. The Study also explores ways to provide a wide range of benefits to both Partnership Tribes and other water users. The mutual trust and understanding forged during the Study will prove to be critical as the Basin collaboratively addresses the significant challenges ahead.

The Ten Tribes Partnership, in its foreword, stated that in addition to producing technical information, the Tribes had other goals. First, they wanted to better understand how, at present, the Study’s water use scenarios fit into the overall scheme of Colorado River Basin management. Second, they wanted to know how future development of tribal water resources will affect other water users who are now using water to which a tribe may hold legal title, but which the title-holding tribe has not yet developed for its own use. Finally, they wanted to assess–to the extent present information allows — the role future development of tribal water rights will have on Basin operations. The Ten Tribes Partnership hopes the Study resolves some uncertainty about how tribes perceive the future for their water uses, and establishes a baseline of information for discussions and development of relationships among tribes, states, federal government, water managers, and water users throughout the Basin.
