California Groundwater Map
This 24" x 36" map shows where groundwater is in California, and explains the different types of water-bearing formations. Cut-aways of different areas in California illustrate the problems of salt water intrusion, contamination, overdraft, and fractured rock. With changes in the way surface water is allocated in California, water users have turned to groundwater to help meet the state's needs.
