Abstract: The project will be operated to maximize energy production from the Sultan River within the operational constraints imposed by the water demand for the City of Everett and by the instream flow requirements at designated points along the river for the maintenance of fish (aquatic) life. The water demand schedule for the City of Everett is presented. A computer program was prepared to simulate the operation of the system in order to develop optimum rules for operation. This study yielded an estimated annual average energy production of 479 gigawatt-hours (GWH). Maximum annual production was 596 GWH and would have occurred in 1950. Minimum annual energy production of 263 GWH would have occurred in 1941. Annual production during the September 1928 to February 1932 critical period would have been 315 GWH.
