DESCRIPTION
Patit Creek, a tributary of the Touchet River in WRIA 32, is home to an ESA listed (threatened) stock of steelhead. The dam was on Broughton Land Company property, approximately one mile above the mouth, and was a partial barrier to both upstream and downstream migration to the spawning and rearing ares in the South Fork Patit Creek, except at the highest stream flows. The dam was removed and two log weirs and two rock weirs were installed as grade control structures to create a step pool reach to facilitate both adult upstream and juvenile downstream passage, as well as control stream degradation and headcutting. The disturbed area was re-vegetated with riparian plantings.
Broughton Land Company (BLC) used this funding to remove a fish passage partial barrier on Patit Creek, a tributary of the Touchet River (WRIA 32), one mile east of Dayton in Columbia County, WA. The creek is home to an ESA-listed (threatened) stock of steelhead. The barrier was an old concrete dam on Company property, approximately one mile above the mouth. The dam limited both upstream and downstream migration except in high stream flows. BLC contracted with Badger Construction, which removed the dam and developed and installed two log and two rock weirs. These grade control structures created a step-pool reach to facilitate both adult upstream and juvenile downstream passage as well as to control stream degradation and head-cutting. Logs with rootwads were incorporated in the pools below each structure to provide resting cover. BLC employees revegetated the site during winter tree dormancy, planting willows and cottonwood whips. The site was seeded with grass species.
