Layer Name:	DAR Streams

Coverage Name:	DarStreams	

Layer Type:	Line

Status:		Complete

Geog. Extent:	Main Hawaiian Islands

Projection:	Universal Trans Mercator, Zone 4 (Meters)

Datum:		NAD 83

Description:	Streams (both perennial and intermittent)
		
Source:		USGS Digital Line Graphs, 1983 version; CWRM Hawaii Stream 
		Assessment database, 1993, DLNR Division of Aquatic Resources,2004.		

History:	Arcs were extracted from the 1983 DLG hydrography layers
		based on the CWRM Hawaii Stream Assessment (HSA) maps and 
		database, then coded with the HSA stream code, and the HSA 
		stream name (1993).  DAR added additional streams from the DLG 
		hydrography layer, and added additional attribute data.
                Further additions, refinement, and editing by DAR in 2003, 2004.
                Additional streams coded and added (NON-PERENNIAL) in 2005.
                OP Staff cleaned up and re-ordered attributes in March, 2005, and
                merged the islands together into one shape file.
