SAWPA GIS tools consist of downloadable data, live maps and applications, and static map galleries.
GIS Data
GIS Layers
GIS layers commonly used by SAWPA including water facilities, hydrologic features and jurisdictional boundaries.
Surface Water Monitoring Data
Analytical data from CEDEN database(through 3/15/2019) for Middle Santa Ana River TMDL Monitoring Program, San Jacinto Watershed-wide Monitoring Program, and Santa Ana River Regional Bacteria Monitoring Program. GIS file of station monitoring locations.
Santa Ana River Annual Report
Analytical data used to compile the Santa Ana River Annual Water Quality Report (2006 -2019).
Evapotranspiration (ET) Data
Includes Total Monthly ET data for locations in the Santa Ana River Watershed, and Upper Santa Margarita Watershed, and South Orange County. Monthly ET is calculated from daily ET downloaded from spatial CIMIS. Data is in file geodatabase format with attribute table containing the monthly ET data.
GIS Live Maps and Applications
Brine Line Mapping Tools
Live maps showing brine line service area and land use zoning near the line for potential customers. Charts showing discharge volume and salt removal statistics for the line.
Water Body Beneficial Uses
View beneficial uses and water quality objectives for Rivers, Lakes, Bays, Wetlands and Groundwater Management Zones designated in the Santa Ana Regional Water Quality Control Board Basin Plan.
Water Agency and City Locator
View water agency and city boundaries. Search for agencies by type and download GIS files of boundaries.
