Description
Columbia River Basin anadromous salmonids have exhibited precipitous declines over the past 30 years, with several populations now protected under the Endangered Species Act (ESA) (Schaller et al. 1999; McClure et al. 2003). The Entiat River subbasin has three listed populations: spring Chinook (Oncorhynchus tshawytscha; listed as endangered in 1999, NMFS 1999b), steelhead (O. mykiss; listed as endangered in 1997, upgraded to threatened in 2006, and relisted as endangered in 2007, NMFS 2007), and bull trout (Salvelinus confluentus; listed as threatened in 1999, USFWS 1999). The Upper Columbia Spring Chinook Salmon and Steelhead Recovery Plan (Recovery Plan, UCSRB 2007) has determined that these populations have a high risk of extinction (more than 25% in 100 years), low abundance and productivity, and are at risk for diversity and spatial structure. The Entiat River drains approximately 1100 km2 (425 mi2) of the eastern slope of the central Cascade Mountains in Washington State, and is a tributary to the Columbia River (Figure 1). The primary historic disturbance processes in the Entiat watershed have been wildfire, flooding, mass soil and debris movement, and land use. Land use has included floodplain and river channel modification projects and structures, grazing, roading, agriculture, timber harvesting, transport of logs within the river channel, dams for log storage ponds and hydropower generation, residential development, and recreation (CCCD 2004).
