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.

Oregon and Washington Framework - Clearinghouse Hydrography Data Dictionary - Physical Data Model, Version 1 (9/22/2000)
Washington Hydrography Framework 1:100,000 scale layers
The layers are statewide shapefiles stored in Ecology's projection/datum standard, Washington State Plane, south zone, NAD83 HARN (feet). Please note that the data dictionary states the data is in the clearinghouse in NAD83 geographic standard, even though it is not here. The download files are zipped (*.zip) files and are formatted according to the Oregon and Washington Framework standards.
