Biologists from federal agencies, universities and private industry also contributed data and reviewed a draft version of this report. We thank them for their time and efforts. We extend special thanks for assistance provided by Lauren Munday, Lori Guggenmos, Larry S. Brown and Darrell Pruett in creating the components of the report and the completed document. This report was funded in part by the U.S. Fish and Wildlife Service under Sportfish Restoration Program contracts F-114-R-1, F-114-R-2 and F-115-R-1.

Changes to the bull trout and Dolly Varden stock inventory in 2004 Genetic analyses of several populations of Washington native char have been conducted since the publication of the 1998 bull trout/Dolly Varden stock inventory. In some cases, we have determined that populations can be identified as bull trout or Dolly Varden. Where species identification has been made, the name of the stock has been changed from bull trout/Dolly Varden to bull trout or Dolly Varden. The basis for these changes is discussed in the introduction to the inventory (p. 2) and at the beginning of each stock report in which the name of the stock was changed. Introduction 1998 Salmonid Stock Inventory Bull Trout/Dolly Varden Volume In 1993, the Washington Departments of Fisheries and Wildlife, along with the Western Washington Treaty Indian Tribes, provided initial results of a stock status inventory for salmon and steelhead (SASSI) in Washington State (Washington Department of Fisheries et al. 1993). The Washington Department of Fish and Wildlife (WDFW) is now extending that effort to other wild salmonid species. The present report is a stock status report for bull trout (Salvelinus confluentus) and Dolly Varden (S. malma), two closelyrelated char species native to Washington State. Separate inventories for each species were not performed due to two major factors: (1) considerable biological similarities exist between the species, and the methodologies to reliably separate them where they coexist have only recently been developed and have not been widely applied, and (2) strong similarities between species exist with respect to life history, habitat, hatchery and fishery management history. The inventory for these two species applies the same conceptual approaches, definitions, criteria, and organizational format that were developed for the earlier inventory for salmon and steelhead. This inventory utilized and extended the earlier inventory effort of Mongillo (1993). Resource inventories are key steps in statewide efforts to maintain and restore wild1 salmonid stocks and fisheries. The primary intent of these efforts is to help identify currently available information and to guide future restoration planning and implementation. Assessment of specific management objectives, strategies, and implementation alternatives will be among the many subsequent steps (e.g., development of a bull trout/Dolly Varden management plan) aimed at improving the status of native char resources. 1998 bull trout/Dolly Varden stock inventory Results of the inventory are summarized by region in the tables below.

The very large proportion of stocks of Unknown status emphasizes the need to collect stock assessment data on these stocks. Many of the Healthy stocks include medium to large spawning populations and represent a large proportion of the total bull trout/Dolly Varden production in Washington. Although Depressed stocks probably have not suffered permanent genetic damage, they may need active efforts to return them to more productive levels. The Critical stocks will require a combination of efforts involving harvest managers, hatchery programs and habitat and stream passage improvements restore them to Healthy status.
