Washington Hydrography Framework

1:100,000 Scale Layer


Background:

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.

Washington Hydrography Framework 1:100,000 scale layers

Please note that we created the original layers in ArcInfo coverage format. They have now been converted to shapefile format and the event tables are in dBase format (DBF).

The layers 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.
