Department of Ecology, in cooperation with the Oregon and Washington Framework Management Group, undertook the data improvement and modification of the existing Pacific States Marine Fisheries Council (PSMFC) StreamNet watercourse and Ecology's water body spatial data layer.
Watercourse improvements consisted of the addition and routing of canals and the restructuring of attributes to meet the draft OR/WA Hydrography Framework physical data structure. Water body improvements included the assignment of unique longitude/latitude identifiers (LLIDs) to all water bodies, the correction of digital line graph (DLG) codes and water body names, the routing and indexing of all shorelines, and the restructuring of attributes to meet the draft OR/WA Hydrography Framework physical data structure.

If you are looking for 1:24,000 hydrography layers, they have been replaced by the National Hydrography Dataset (NHD). They are available at the USGS's National Hydrography Dataset website.
