DNR Hydrography - Watercourses

DNR Water Bodies (WB) and DNR Watercourses (WC) collectively known as DNR Hydro, contain water feature location and water type that is used by the Forest Practices program to determine the amount and pattern of riparian buffer protection required during forest practices activities.  The water type is a Washington State Department of Natural Resources (DNR) classification system of streams and water bodies that identifies whether or not streams/water bodies have potential fish habitat, and whether or not streams experience perennial or seasonal flow.

WC Hydro represents water courses as arcs or lines. These occur alone as single arcs representing streams, ditches, or pipelines, or as centerlines through water body polygons such as double-banked streams, lakes, impoundments, reservoirs, wet areas, or glaciers. WB represents water bodies as polygonal features. WB Hydro includes features such as Puget Sound, lakes, wet areas, reservoirs, impoundments, glaciers, islands, and dams. WS represents shorelines as polygon perimeter arcs and are edited coincidentally with WB.  WC and WB are edited daily and simultaneously; updates are posted weekly for internal DNR use and monthly for external use. Routes can be built on the WC by using the whole stream identifier (WC_LLID_NR). DNR HYDRO is continually updated through the DNR Forest Practices Water Type Modification Form process. DNR HYDRO is mixed scale. The nominal scale is considered 1:24,000, but some data at larger scales are included.Watercourses Layer Metadata
