Known Freshwater Distribution of Salmon and Trout
We produced these maps to create a consistent, shared understanding of what is known and not known about salmon and trout distribution and to Identify areas where improvements to hydrographic information (e.g., channel location and configuration) are and are not needed. This is an initial step toward a longer term WRIA-based effort to produce regular updates to maps depicting salmon and trout distribution and hydrography and make them available to a broad audience.

Process for Compiling Salmonid Distribution Maps
The initial steps of salmonid distribution mapping project relied primarily upon the direct knowledge of technical staff regarding distribution, documentation of distribution in reports and studies, and existing depictions (i.e., GIS layers) of river and stream channel location and configuration. To gather this information, technical staff from jurisdictions, agencies, tribes and stakeholder groups participated in an information-sharing workshop in May of 1999. At the initial workshop, only data from 1985 to 1999 was included. In February of 2000, the WRIA 8 Technical Committee met and decided to include data from 1970 to 2000 as long as the data was collected under standard protocols. This was done due to the large numbers of surveys in the early 70's done by WDFW.
The fish data on the map is represented with lines and points. Each point has specific data corresponding to it in the data table. The table includes the source of the sighting, stream name, and a description of the sighting. Many of the points also have information on the lifestage and year of the sighting. These categories were added after the initial workshop so not all the points have this data. The only fish attribute shown on the maps is first and second hand distribution information. First hand data (red) represents fish seen by the source in the data table. Second hand data (green) represents information given to the source by another person (i.e. fishermen, homeowners).
