*Abstract:* Reclamation delivers Colorado River water to water users for diversion and beneficial consumptive use in the States of Arizona, California, and Nevada. The Consolidated Decree of the United States Supreme Court in the case of *Arizona* v. *California, et al.,* entered March 27, 2006 (547 U.S. 150 (2006)), requires the Secretary of the Interior to prepare and maintain complete, detailed, and accurate records of diversions of water, return flow, and consumptive use and make these records available at least annually. The information collected ensures that a State or water user within a State does not exceed its authorized use of Colorado River Water. Water users are obligated by provisions in their water delivery contracts to provide Reclamation information on diversions and return flows. Reclamation determines the consumptive use by subtracting return flow from diversions or by other engineering means.
