Reclamation Climate Change and Water, Report to Congress, 2011

This report is prepared in fulfillment of the requirements within section (§) 9503 of the SECURE Water Act and provides an assessment of climate change impacts on the quantity of water resources located in each major U.S. Bureau of Reclamation river basin. The eight river basins identified include the Colorado, Columbia, Klamath, Missouri, Upper Rio Grande and Pecos, Sacramento - San Joaquin, and the Truckee - Carson. 

The report provides basin-specific discussions, reviewing the basin setting, basin specific coordination, historical climate, historical hydrology, projected future climate and hydrology, and implications for various water and environmental resources in each of eight sections.  The section following integrates findings from the basin-specific discussion to provide a west-wide perspective on projected climate and hydrologic changes.

In addition, Section 11 of the report highlights six projects where Reclamation is involved in adaptive actions being implemented.


The Omnibus Public Land Management Act of 2009 (Public Law 111-11) Subtitle F – SECURE Water, also known as the SECURE Water Act, was passed into law on March 30, 2009.  The Act authorized the Bureau of Reclamation to continually evaluate and report on the risks and impacts from a changing climate and to identify appropriate adaptation and mitigation strategies utilizing the best available science in conjunction with stakeholders.
