Description: WCHYDRO and WBHYDRO together make up the most complete and up to date hydrography layer for the State of Washington. WCHYDRO contains watercourses represented as arcs or lines. These occur alone as single arc watercourses representing streams, ditches, or pipelines, or as centerlines through water body polygons such as double-banked streams, lakes, impoundments, reservoirs, wet areas, or glaciers. WBWS (WBHYDRO) and WC (WCHYDRO) are edited daily and simultaneously. Attribute interrelationships within WBWS (WBHYDRO) and spatial and attribute interrelationships between WBWS (WBHYDRO) and WC (WCHYDRO) are maintained.
