CDFG - 100k Streams 2003

Cdfg_100k_2003_6.shp is a 1:100,000 scale stream based routed hydrography covering the entire State of California. This measured shapefile was derived from an Arc/Info coverage. The coverage utilizes existing National Hydrography Database (NHD) 1:100,000 linework and attributes as well as Geographic Names Information System (GNIS) identifiers as guidelines to determine the stream networks that were referenced into routes. Utilizing both automatic routines developed by California Department of Fish and Game (CDFG) and Pacific States Marine Fisheries Commission (PSMFC) staff as well as manual (on screen) networking techniques, a series of arcs from the NHD were networked into a stream first by the existence of a GNIS stream ID. If no GNIS stream ID was present for a series of arcs, like NHD "Level" attributes were used to determine the network. The resulting routes represent what are commonly referred to as streams under the aforementioned guidelines. Streams are catalogued with a unique LLID identifier. Although derived from Latitude/Longitude coordinates, the LLID should be used as a stream identifier only and not as a spatial identifier.
