Delineates the legal Delta established under the Delta Protection Act (Section 12220 of the Water Code) passed in 1959.
The original topographic maps containing the drawn delta border were scanned from the Department of Water Resources. Images were registered to 1:24,000 USGS DRG's in ArcView (ESRI) utilizing imagewarp extension. The Delta boundary was digitized from the registered images. Accuracy within acceptable 7.5 Minute USGS map accuracy standards (1:24000 scale). Delta boundary version 2002.4. The original legal boundary maps obtained from the Delta Protection Commission were compiled by DWR Land & Right of Way sometime in the early 1980's. They were based from the legal description in section 12220 of the Water Code, with ambiguities in the Code addressed by the individuals involved in the mapping project at that time. One revision was made to the original maps in the vicinity of Point Pleasant, and is the only difference between this and the 4.2001 version of the legal Delta boundary Arc/INFO coverage.
