Summary

Delineates the legal Delta established under the Delta Protection Act (Section 12220 of the Water Code) passed in 1959.

Description

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.

Supplemental information
First draft completed 4/25/2002. Received from Chico State by DWR Central District Delta Levees Program 5/31/2001. Converted from shapefile into coverage format, reprojected from Teale Albers into UTM Zone 10, rebuilt topology, evaluated against basemaps and pre-existing boundary layers, and cataloged into Delta GIS Library (all using Arc/INFO 8.0.2) by Joel Dudas, 5/2001. The revision between the 4.2001 and the 4.2002 versions reflects a change in the vicinity of Point Pleasant in the east Delta, as shown on modified Delta Protection Commission maps. The line was moved south to the township boundary line, as appropriate, using ArcGIS 8.1 software. During 2001 & early 2002 every effort was made to identify any errors in the underlying data sources, including water district, reclamation district, roads, etc. boundaries. While certain features were not able to be 100% certified, this coverage can be considered to be as accurate based on all of the information available at this time.
* Processing environment Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.1.1.3143
