GUSTINE, CA - JULY 16:   A buoy is seen lying in the sand at the bottom of the San Luis Reservoir on July 16, 2007 in Gustine California. California Governor Arnold Schwarzenegger stressed the importance of a comprehensive water plan as the current system is not prepared to handle the population growth projected for the next 50 years. The reservoir which is filled to just 20.797 percent of capacity and is down 186 feet from normal levels supplies water for the Silicon Valley, Central Valley farms and Southern California homes and businesses.
