Fully Appropriated Streams

Water Code sections 1205 through 1207 establish a procedure for the State Water Resources Control Board (State Water Board) to adopt a declaration designating stream systems which are determined to be fully appropriated either year-round or during specified months. The State Water Board may act on its own motion or on petition of any interested person. On November 16. 1989, the State Water Board adopted the “Order Adopting Declaration of Fully Appropriated Stream Systems and Specifying Conditions for Acceptance of Applications and Registrations” (Order WR 89-25). In response to a petition for reconsideration, the State Water Board adopted an order modifying Order WR 89-25 and affirming Order WR 89-25 as modified (Order WR 90-02). The State Water Board subsequently adopted updated and revised orders by the same name on August 22,1991 (Order WR 91-07), and on November 19, 1998 (Order WR 98-08). Orders WR 89-25, WR 91-07 and WR 98-08 were based upon previous water right decisions or orders which determined that no water remains available for appropriation from the specified sources during particular months.

The following tables contain links to Exhibit A of Order WR 98-08 and downloaded schematics which delineate the Critical Reach of Stream Systems which have been declared by the State Water Board to be Fully Appropriated. As described in Order 89-25 and subsequent orders, any declaration that a stream system is fully appropriated encompasses all upstream sources which contribute to the stream system if, and to the extent that, such upstream sources are hydraulically continuous to the stream system. Further, as described in Order 91-07, stream systems designated on the State and Federal Wild and Scenic River Acts were added to the Declaration of Fully Appropriated Streams to recognize the restrictions on appropriation of water contained in the respective State and Federal acts, not to declare that the listed stream systems are fully appropriated.
