DESCRIPTION
In 2022, the Confederated Tribes of the Umatilla Indian Reservation completed the third summer of construction to improve habitat for summer steelhead trout, spring Chinook salmon, and bull trout in the North Fork Touchet River near Dayton. Working with several private landowners, the tribes used several techniques to improve habitat in the stream and its floodplain. Construction crews built log and boulder structures to encourage pool formation and provide overhead cover for fish, set back levees that previously confined the river, and replaced a bright with a longer span to allow the river to engage with its newly broadened floodplain. Projects that reconnect rivers with their floodplains are important salmon recovery tools. These are often complex, challenging projects because floodplains throughout Washington have been modified to provide agricultural, residential, commercial, and industrial benefits to society. In this case, grants and innovative partnerships combined to improve salmon and steelhead habitat while increasing climate resilience, reducing flood risk, and protecting agricultural uses. Encompassing 3 miles of the North Fork Touchet River, the project reconnected 44 acres of floodplain with the river, planted 32 acres with native trees and shrubs, built nearly 2 miles of levee to protect adjacent farms, and placed 192 large wood structures and logs in the river to create habitat for fish.
