The Congdon canal diversion (approximately 55 cfs) is located on the right bank of the Naches River about 4 miles east of Naches, Washington and adjacent to Eschbach Park.

The screening facility includes three rotary drum screens that are each 4 feet in diameter by 12 feet long. Screens are constructed of 4.5 mesh by 12 gauge (4.5-12) stainless steel woven wire mesh. The openings are approximately 1/8 inch.

The bypass is a full-depth, 18-inch wide rectangular channel that is 11 feet long. An adjustable weir gate at the end of this channel controls flows that then drop into 3-foot wide by 8-foot long downwell. Bypass flows are then conveyed through a 12-inch diameter PVC pipe to the outfall.
