The Klickitat Floodplain Restoration Phase 4 project enhanced and restored riparian and floodplain habitat between river mile 22.52 and 23.85 of the Klickitat River. The project addressed limiting habitat features and processes identified in the 2012 Klickitat Lead Entity Salmon Recovery Strategy for this reach by fill removal and pull back of floodplain road to restore connectivity, establish river contact with bedrock, and soften channel boundary along 1.33 miles of road which included riparian plant removal and control and fish passage barrier removal. Treated areas were revegetated with native species to enhance riparian vegetation and improve near-bank and off-channel habitat conditions for steelhead and salmon. This portion of the river has the greatest habitat complexity of any reach in the lower Klickitat River and provides critical spawning, migration and rearing habitat for winter and summer steelhead (ESA-Threatened), spring and fall chinook salmon, and coho salmon. The project is encompassed by the "Lower Klickitat Mainstem: Little Klickitat to Leidl Bridge" reach, which is in the top tier ("A" priority) of the geographic priorities identified in the 2012 Klickitat Lead Entity Salmon Recovery Strategy. This reach provides a high proportion of basinwide spawning habitat for all three species, accounting for roughly 30%, 51%, and 38% of the annually observed spawning for steelhead, fall chinook, and coho respectively. Phase 4 continued the SRFB funded work beginning in 2004 with the acquisition of the Haul Road and three phases of restoration projects since.
