Lindsey

The Lindsey Ditch Diversion (approximately 20 cfs) is located on the right bank of the Naches River about two miles upstream of the Rattlesnake Creek confluence in Yakima County, Washington. The current Lindsey fishscreen facility replaces a screen that did not adequately protect juvenile and adult anadromous fish during canal diversions.

The facility now consists of one rotary drum screen, 3 feet in diameter by 12 feet long. The screen is constructed of perforated stainless steel with 3/32-inch diameter holes on 5/32-inch staggered centers.

The bypass entrance channel is a full-depth, 18-inch wide rectangular channel that is 9 feet long. An adjustable weir gate at the end of this channel controls flows that then drop into 3-foot wide by 6-foot long downwell. Bypass flows are then conveyed to the Naches River through an 18-inch diameter PVC pipe for 27 feet to the river.
