Representatives of the seven Colorado River Basin states meet today at a conference in Las Vegas to discuss the details of a long-awaited plan for dealing with drought. Cities, farms, and tribal nations are negotiating voluntary cutbacks in water use to reduce the risk of Lake Mead falling to catastrophically low levels. KNAU’s Melissa Sevigny spoke with one of the conference moderators, John Fleck, a water expert from the University of New Mexico, about why this “Drought Contingency Plan” is needed.
