Concerns about the decline of native salmon and trout populations have increased among natural resource managers and the public in recent years. As a result, a multitude of initiatives have been implemented at the local, state, and federal government levels. These initiatives include management plans and actions intended to protect and restore salmonid fishes and their habitats.
In 1998 bull trout were listed under the Endangered Species Act (ESA), as â€œThreatenedâ€, for the Walla Walla River and its tributaries. Steelhead were listed as â€œThreatenedâ€ in 1999 for the midâ€“Columbia River and its tributaries. These ESA listings emphasize the need for information about the threatened salmonid populations and their habitats.
The Washington Department of Fish and Wildlife (WDFW) is entrusted with â€œthe preservation, protection, and perpetuation of fish and wildlife....[and to] maximize public recreational or commercial opportunities without impairing the supply of fish and wildlife (WAC 77.12.010).â€ In consideration of this mandate, the WDFW submitted a proposal in December 1997 to the Bonneville Power Administration (BPA) for a study to assess salmonid distribution, relative abundance, genetics, and the condition of their habitats in the Walla Walla River basin.
The primary purposes of this project are to collect baseline biological and habitat data, to identify major data gaps, and to draw conclusions whenever possible. The study reported herein details the findings of the 2000 field season (March to November, 2000).
