The story of water is the story of food, from irrigation on the farm to the tap water we boil for a pot of soup or a cup of tea. This week marks the 100th anniversary of the Los Angeles aqueduct. KCRW's Madeleine Brand hosted a riveting radio documentary called Power and Water: The Los Angeles Aqueduct at 100. The special feature documents the who, the how and the why of the water wars that William Mulholland launched a century ago. During her reportage - Brand visited a cattle rancher in the Owens Valley who says those water wars aren't over.
