Layer: DEQ Hydrography (LLID) (ID: 0)

Name: DEQ Hydrography (LLID)

Display Field: NAME

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: The DEQ_Streams feature class combines geospatial files from both 1:100,000 (1:100K) and 1:24,000 (1:24K) scales as needed to represent water bodies where water quality information was assessed for the 2010 Integrated Report. The bulk of the stream network presented in the DEQ_Streams feature class is from the 1:100K scale data originating from StreamNet100K, described below. Attributes including Longitude/Latitude Identifier (LLID) and water body name from the 1:100K dataset were used if available. When water bodies were not represented in the 1:100K dataset, line work from the USGS 1:24K stream layer, Pacific Northwest 24K (from Pacific Northwest Hydrography), NHD High, and NHD Med were added to the 1:100K dataset as needed. In addition, some line work was modified to correct line work gaps, inaccuracies, or errors in the feature class. For example, DEQ added a"stream" line to represent the Pacific Ocean coast line and calculated a latitude/longitude identifier (LLID), river mile minimum and river mile maximum end values. For DEQ assessment purposes, the Pacific Ocean river mile start (RM 0) was set at the Oregon/Washington border with river miles increasing from north to south to a river mile maximum (RM 357.97) at the Oregon/California border. Oregon coastal recreation beaches were assigned river miles representing start and end points for segments along the Pacific Ocean line that are used for the 2010 IR. Contact DEQ to obtain the dataset.
