The Los Angeles Times reports that the Metropolitan Water District covering 16 million people in six counties of southern California has been able to maintain water supplies because of pre ENSO planning, such as identifying systems that might suffer from heavy runoff. Several areas of water main had their protective soil layers washed away; repairs are estimated to cost $400 K. However, ENSO runoff has forced a leak in the California Aqueduct that moves water from northern to southern California. Repairs will take one to two months and water supplies are not expected to be affected.
