Description    


The Cowlitz Indian Tribe placed large wood structures in a high priority area of Abernathy Creek to enhance instream habitat for coho and winter steelhead. The project site is located in upper Abernathy Creek west of Longview, WA on Department of Natural Resources land. The Tribe installed three anchored engineered log jams to encourage stable side-channel habitat, and several smaller accumulations of wood in the channels and floodplain to catch and sort gravels and provide spawning and rearing habitat. Tribe staff planted trees and shrubs in the riparian area to increase long term habitat values and restore areas disturbed by heavy equipment during construction. This reach of Abernathy Creek supports populations of winter steelhead, a Primary population for regional recovery goals, coho salmon, ESA-listed (threatened), and coastal cutthroat trout. This project builds upon previously funded design and construction projects in the Mill-Abernathy-Germany subbasin, and will support the goals and objectives of the Intensively Monitored Watershed program for the Lower Columbia region.

Project Benefit    


The goal of this project is to restore stable floodplain and channel features historically provided by old-growth in-stream wood to support coho and steelhead rearing and spawning habitat in the project area of Abernathy EDT reach 10. The specific objectives are:
• Maintain a stable high-flow side channel for winter rearing by installing an ELJ at the head of the currently perched channel and aggrading the mainstem with wood placements;
• Encourage stable pool formation associated with three engineered log jams and other wood placements;
• Improve riparian conditions on a decades-scale by under-planting alder and maple forest with shade tolerant conifers such as grand fir, western redcedar, and Sitka spruce in selected areas surrounding the instream project area; and
• Place 65 total pieces of large wood to provide cover for adult and juvenile salmonids, catch mobile instream wood and debris, and foster enhanced biofilm and macroinvertabrate production in the project reach.
