PROJECT DESCRIPTION

The Wallowa-Whtiman National Forest (WWNF)La Grande Ranger

District seek to enhance and restore fish habitat along approximately 2 miles of the Upper Grande Ronde River on private land. The Project is planned for construction during summer 2024The Project includes large wood additions to promote pool development, island braiding and side channel development, increased habitat diversity, and sediment routing and storage. A total of XX large wood structures, consisting of alluvial wood debris/channel spanning, apex, and cover wood structures.

Targeted fish populations include Endangered Species Act (ESA) listed

Snake River spring-summer Chinook salmon and summer steelhead.

Habitat improvements will also benefit bull trout, Pacific lamprey, and resident native fish. The project area provides critical spawning and rearing habitat for targeted fish populations.

The Project was designed in accordance with Aquatic Restoration

Activities Biological Opinion (ARBO) conservation measures and project design criteria.
