Water Right Decision 1641 (Revised)

The State Water Resources Control Board adopted Decision 1641 on December 29, 1999. The Decision implements flow objectives for the Bay-Delta Estuary, approves a petition to change points of diversion of the Central Valley Project and the State Water Project in the Southern Delta, and approves a petition to change places of use and purposes of use of the Central Valley Project.

The SWRCB received 21 timely petitions for reconsideration of D-1641, and on March 15, 2000 the Board adopted Order WR 2000-02.  Order WR 2000-02 denies the petitions for reconsideration of D-1641, clarifies findings made in D-1641, and amends several conditions of the order in D-1641.
