About the entity

U.S. Department of the Interior
The U.S. Department of the Interior manages natural resources and cultural heritage; provides scientific information about those resources; and honors its trust responsibilities to American Indians, Alaska Natives, and affiliated Island Communities.

The Biden-Harris administration announced an agreement with the Imperial Irrigation District (IID) that will conserve approximately 100,000 acre-feet of water in Lake Mead in 2023. The agreement includes approximately $77.6 million in new investments from President Biden’s Investing in America agenda, which will fund projects for water conservation, water efficiency, and protection of critical environmental resources in the Colorado River System this year.

The investments, which are part of the Biden-Harris administration’s whole-of-government approach to improve and protect the stability and sustainability of the Colorado River System now and into the future, are administered through the Lower Colorado River Basin System Conservation and Efficiency Program and funded by the Inflation Reduction Act, the largest climate investment in history.

In addition, Reclamation and IID continue to work on an agreement for years 2024 through 2026. Combined, the IID agreements over the next three years are expected to achieve up to 800,000 acre-feet of system water conservation to shore-up elevations in Lake Mead for the benefit of the Colorado River System and the over 40 million people who rely on it.

"Through President Biden’s Investing in America agenda, the Lower Colorado River Basin System Conservation and Efficiency Program is helping address, improve and protect the long-term stability of the Colorado River System,” said Principal Deputy Assistant Secretary for Water and Science Michael Brain. “The Biden-Harris administration is using every tool and resource at our disposal to continue our sustained, collaborative progress in increasing water conservation across the West.”

“We are grateful for the Imperial Irrigation District’s leadership and partnership as we worked to execute this agreement,” said Reclamation Commissioner Camille Calimlim Touton. “Addressing the drought crisis requires an all-hands-on-deck moment and close collaboration among federal, state, Tribal and local communities. IID’s commitment to system conservation is vital as we work to strengthen the stability of the entire Colorado River Basin.”

President Biden’s Investing in America agenda is integral to the efforts to increase near-term water conservation, build long term system efficiency, and prevent the Colorado River System’s reservoirs from falling to critically low elevations that would threaten water deliveries and power production.

The IID agreement announced is in addition to the 18 recently announced agreements executed in Arizona that commit water entities to conserve up to 348,680-acre feet of water in Lake Mead in 2023, and up to 984,429-acre feet through 2026. The agreements are part of the 3 million acre-feet of system conservation commitments made by the Lower Basin states, 2.3 million acre-feet of which will be compensated through funding from the Inflation Reduction Act.

Through the Bipartisan Infrastructure Law, Reclamation is investing another $8.3 billion over five years for water infrastructure projects, including water purification and reuse, water storage and conveyance, desalination, and dam safety.

As a result of the commitment to record volumes of conservation in the Basin, as well as recent hydrology, Interior Department announced in October that the chance of falling below critical elevations has been reduced to eight percent at Lake Powell and four percent at Lake Mead through 2026. Lake Mead is currently about 40 feet higher than it was projected to be at this time last year.

To date, the Interior Department has announced the following investments for Colorado River Basin states through the Bipartisan Infrastructure Law and Inflation Reduction Act, which will yield hundreds of thousands of acre-feet of water savings each year once these projects are complete:
