Division of Water and Power

It is the mission of the Division of Water and Power (DWP) to promote self-determination, economic opportunities, and public safety through the sound management of irrigation, dam, and power facilities owned or operated by the Bureau of Indian Affairs (BIA). In support of this mission, DWP is committed to the following:

  • Hiring, training, and retaining highly qualified personnel to manage, operate, maintain, construct, and rehabilitate DWP infrastructure (and to conduct financial matters that support these activities). 
  • Providing our stakeholders with quality services and improved accountability, including protecting and preserving life, property, and trust resources.
  • Assisting tribes in the management of water resources through measurement, analysis, and modeling.
  • Promoting the transfer of management, administration, operation, maintenance, and rehabilitation of irrigation, dam, and power facilities to tribes, irrigators, and water user associations.
  • Fostering communication, cooperation, and consultation among Federal, State, tribal, and local organizations related to water resources, irrigation, power, dam safety, security, and emergency management activities.
  • Promoting state-of-the-art technologies to improve the management and conservation of water resources in a sustainable manner, while maximizing the economic benefits to our stakeholders.
  • Encouraging modern business practices and innovative business techniques to meet the ever-changing needs of our stakeholders.


The DWP is responsible for the management, operation, maintenance, and asset management of BIA-owned Irrigation and Power projects, and under the Safety of Dams (SOD) program, for maintenance and rehabilitation of dams on Indian lands. DWP also includes the recent addition of Water Resources management.

The DWP Central Office staff provide policy, oversight, advisory, and technical support to regions and agencies on Water Resources, Irrigation and Power, and SOD. Central Office staff are located in Washington D.C., Lakewood, Colorado, Portland, Oregon, Billings, Montana, Phoenix, and Coolidge, Arizona. Central Office contact information is listed below:
