The money has been approved for 4 new dams and 4 underground water storage projects in California. The 2.5 billion dollars came from the 2014 water bond known as Proposition 1. It is believed to be the largest commitment of money to construct new dams and water storage projects in California since 1960. Local agencies, where the dams and water storage projects will be constructed, still need to raise the rest of the money through other sources (including asking for federal funding, partnerships with other water districts, and raising local water rates).
