Title

Proposed Extension Petition for the Interim Instream Flow Requirements Under State Water Resources Control Board Revised Water Right Decision 1644

Description

Yuba County Water Agency (YCWA) filed a petition for modification of water right permits 15026, 15027, and 15030. The petition requests that the State Water Board change the effective date of the long-term flow requirements established in Revised Decision 1644 to March 1, 2007. The long-term flow requirements are scheduled to come into effect on April 21, 2006. Until that date, RD-1644 requires YCWA to maintain instream flows in the lower Yuba River that are equal to or greater than specific interim flow requirements. The interim and long-term flow requirements established in RD-1644 vary depending upon the time of year and the hydrologic conditions in a particular year. The long-term flow requirements are higher than the interim requirements during parts of some years, but are the same as the interim requirements for water years that are classified as wet or above normal under the criteria specified in RD-1644. The petition was submitted in order to allow for implementation of the 2006 Pilot Program for the proposed Yuba River Accord (Accord) which was developed to help resolve conflicts and ongoing litigation related to stream flows and water use in the lower Yuba River.
