Summary: The Salton Sea, the largest lake in Southern California, provides critical wildlife habitat. While it was once part of a vast inland sea, more recently water in the lake has come largely from irrigation runoff and leaching.
Summary: California uses approximately 15 billion gallons of groundwater per day, more than any other state in the United States. Currently, groundwater accounts for about half of Californias water supply.

Summary: Methylmercury is found in low or no oxygen environments and can be toxic to wildlife at low levels. Studies from the Yolo Bypass in the Sacramento-San Joaquin Delta suggest that rice systems may be a significant source of methylmercury in the Delta.
Summary: High-volume hydraulic fracturing is a relatively new and controversial form of natural gas and oil drilling that is poised for a boom in California. This type of fracking is water-intensive and could exacerbate water stress.
