Snipes - Allen

The Snipes Allen canal diversion (approximately 25-30 cfs) is located on the left bank of the Yakima River near Buena, Washington. The current Snipes Allen fishscreen facility was completed in 1993.

The facility now consists of two rotary drum screens, each 4 feet in diameter and 12 feet long. The screens are constructed of 4.5-12 woven wire mesh (1/8-inch openings).

The bypass entrance channel is a full-depth, 18-inch wide rectangular channel that is 10 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 an 18-inch diameter PVC pipe for approximately 500 feet to the river.
