Hydrography Framework Priority Data Cleanup 1:24K

For the Water Resource Inventory Area – Snohomish River (WRIA 7), updated the existing Ecology/King Co. 1:24,000 scale dynamically segmented hydrography data and included surface water changes to the hydrography data as mapped by Snohomish County. Using the USFS hydrography conflation tool moved the existing 1:100,000 Latitude/Longitude Identifiers (LLID’s) to the 1:24,000 scale data and uniquely identified all other streams in the WRIA. The physical data structure follows the draft Hydrography Framework Data Dictionary.
