Chandler Canal


The Chandler Screens (Figure 1) are located in the Chandler Canal on the right bank of the Yakima River. The head gates of the Chandler Canal withdraw water from the Yakima River at the Prosser Diversion Dam at river mile 47.0 near Prosser, Washington. The facility consists of 24 rotary drum screens (13.5 ft diameter, 12 ft long) and a fish bypass system that includes three fish bypasses (two intermediate and a terminal), a separation chamber with four bypass water recovery pumps located behind vertical traveling screens, and a fish return. The forebay elevation is about 631 ft at the maximum canal flow of 1400 cfs.
