Private Water District boundaries are areas where private contracts provide water to the district in California. This database is designed as a regions polygon database and is updated when sufficient number of changes have occured to warrant an update. Updates are determined by the needs of the local office. Separate databases are used for maintenance purposes. Boundaries are continually being updated as changes are identified by the Water Districts. The boundaries are not current for all Water Districts found in the database at the same time due to the update methods employed. There may be conflicts in the boundaries between districts due to the time of update and review process associated with each Water District. Other problems may be associated with Water District name changes that have not been updated and possibly new Water Districts not being included due to lack of information. This database represents the most current and accurate understanding of the boundary location and current name of the Water Districts.

The Private Water District boundaries database is cooperatively shared between the U.S. Bureau of Reclamation (USBR), Mid-Pacific regional office (MP), MPGIS Service Center and the California Department of Water Resources (DWR). The USBR maintains this database with the voluntary assistance of the Private Water Districts. This database allows the USBR and DWR to display and analyze this information.

This database is not intended to be used as a land survey or representation of land for conveyance or tax purposes. The database is available to all users that may require this information.

California Department of Forestry and Fire Protection (using data from BOR and DOC FMMP) 2004 County Boundaries (1:24000) vector digital data gis.ca.gov/casil/boundaries/cnty24k In late 1996, the Dept of Conservation (DOC) surveyed state and federal agencies about the county boundary coverage they used. As a result, DOC adopted the 1:24, 000 scale Bureau of Reclamation dataset (USGS source) for their Farmland Mapping and Monitoring Program (FMMP) but with several major and minor modifications. Detailed documentation of these changes is provided by FMMP and included as part of the data dictionary. Ideally, state and federal agencies should be using the same framework data for common themes such as county boundaries. This layer provides an initial offering as "best available" at 1:24,000 scale. Additional improvements, including a review of data sources for the coastline, can be added over time based on interagency review and agreement on proposed changes.

California Department of Forestry and Fire Protection 2004 Bioregions.

California regions developed by the Inter-agency Natural Areas Coordinating Committee (INACC) were digitized from a 1:1,200,000 California Department of Fish and Game paper map. The 2004 update utilizes the 1:24,000-scale county boundaries, coastline and state boundary from the CMCC Framework data layer CNTY24K97_1. The North and South Sierra bioregions have also been collapsed to form one region,Sierra. The INACC regions have been adopted for use as bioregion boundaries by the California Biodiversity Council (CBC).
