The Yuma Field Office produces a monthly report of provisional flow data for the Lower Colorado River, its tributaries, and selected diversion and return flow sites. Many of the locations included in the data report are a part of Reclamation’s Decree Accounting Record to comply with Article V of the Decree of the Supreme Court of the United States in Arizona v. California dated March 9, 1964. Other sites included in the report are for planning and forecasting purposes and are used by numerous Colorado River water users. While the flow data in this report is considered provisional, it has been through an internal analyzation and review process.
Monthly reports will no longer be accessible online. Please contact Hugh Darling for information on how to receive monthly reports via email.
