Geometry Type: esriGeometryPolyline

Description: WBDLine: This geospatial dataset represents arcs for the Watershed Boundary Dataset (WBD) layer for Oregon and it contains complete coverage of hydrologic boundaries, mapped to the 6th level (12-digit). The arcs for each boundary are defined by hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream, or similar surface waters. Hydrologic units within the WBD can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. These arcs for the Oregon WBD were delineated by Pacific Northwest (PNW) Hydrography Framework Partners to meet state requirements and to contribute to the national WBD repository. To meet these goals, the WBD must adhere to the "Federal Standards for Delineation of Hydrologic Unit Boundaries", dated October, 2004. The Oregon dataset has been given national certification by the Natural Resources Conservation Service (NRCS). Prior to submission the dataset was subjected to an iterative review and edit process to ensure that the hydrologic boundaries fully satisfy the federal standards. This work was completed under a Memorandum of Understanding between the Pacific Northwest Hydrography Framework Partnership and the US Geological Survey (USGS).
