Why El Nino will not be enough.

The map shows the critical state of California reservoirs. Even if El Nino brought enough water to California our existing reservoirs could not contain the volume of water needed. There are new reservoirs being constructed such Headworks, which would be the largest underground drinking water reservoir. Here is why it is underground. The majority of rain water that falls in southern California is channeled to the sewers and eventually out to the Pacific Ocean. This is part of my research why more need to be done to capture rain water.
