The Little Naches Levee Reach

The Little Naches Levee Reach Restoration Project improved 1.24 miles of river that is home to resident cutthroat and rainbow trout, mountain whitefish, steelhead, bull trout, coho, and spring Chinook salmon.

The river in this reach was damaged by past human actions, including removal of log jams, bulldozing of the stream channel, and construction of two large levees on both sides of the river. These actions left the river disconnected from the floodplain, and increased the power of high flows.

As part of the project, nearly 1,000 feet of large angular rocks that created an armored bank and both levees were removed (totaling almost 17,000 cubic yards of material) except for about 300ft which was left in place to further protect the road. Much of the levee material was used in the project to rebuild the streambed.

The project included construction of 65 engineered wood structures, plus the addition of 100 single logs to improve the geomorphic, hydrologic, and ecological function of the river. All disturbed areas were seeded with native grasses and mulched, and boulders were placed to prevent vehicular access.

The project was funded by a Streamflow Achievement grant from the Department of Ecology, the US Forest Service, and the Yakima Basin Integrated Plan. The project was designed by Tetra Tech, Inc. and constructed by BCI Contracting.
