Southern California Water War -- NPR's Carrie Kahn reports on an 85-year-old water war between the city of Los Angeles and the community of Owens Valley. The dispute centers on Owens Lake which was drained by Los Angeles to bring water to its growing population. What remained was a dry lake bed filled with toxic dust. Los Angeles was ordered to clean up the dust in 1983, but has failed to do so. Now, the state says Los Angeles and Owens Valley must reach a compromise by the end of the month or the federal government will intervene.
