NOTICE: Ecology's web applications will be unavailable Wednesday, Nov. 29 from 5:30 to 7:30pm, for scheduled maintenance.
This section contains maps by WRIA(1) that show, in greater detail, the streams
that Ecology protects for native char.
Note: information in these maps should be used for general purposes only. This data was superseded during the 2006 rule revision. Current designated char waters can be found in Table 602 of the 2006 Water Quality Standards.
Please select a WRIA using the map below or the links on the right side of this page.
List of WRIAs
1 The Department of Ecology and other state resource agencies frequently use a system of "Watershed Resource Inventory Areas" or "WRIAs" to refer to the state's major watershed basins. Federal agencies frequently use an alternative watershed system based on USGS Cataloging Units or "HUCs" (Hydrological Unit Codes). The federal system is similar to the WRIA system except for differing basin groupings and the federal units extending beyond the Washington state boundary into Canada, Oregon, and Idaho. Some of our WRIA maps show portions of the overlapping USGS Cataloging Units where they help to show how watersheds extend past the state boundary.
