Colorado River Basin Water Supply and Demand Study

Secretary of the Interior Ken Salazar has announced the release of a study – authorized by Congress and jointly funded and prepared by the Bureau of Reclamation and the seven Colorado River Basin states – that projects water supply and demand imbalances throughout the Colorado River Basin and adjacent areas over the next 50 years.

Landscape Conservation Cooperatives

Secretarial Order No. 3289 establishes Landscape Conservation Cooperatives (LCCs), a network of public-private partnerships that provide shared science to ensure the sustainability of America's land, water, wildlife and cultural resources.

Water Efficiency

Water is one of our most precious natural resources, and although the United States has an abundant supply, it is not evenly distributed throughout the country. Recent droughts illustrate that many areas are severely undersupplied. Federal facilities have a tremendous opportunity to lead by example within their communities to showcase innovative and cost-effective water efficiency strategies.

WaterSMART Three-Year Progress Report

The program was launched by Secretary of the Interior Ken Salazar in 2010.

The WaterSMART Challenge

WaterSMART is the U.S. Department of the Interior's sustainable water initiative that uses the best available science to improve water conservation and help water resource managers identify strategies to narrow the gap between supply and demand. Since its establishment in 2010, WaterSMART has provided about $200 million in competitively awarded funding to non-federal partners, including tribes, water districts, municipalities and universities through WaterSMART Grants and the Title XVI Program.
