The worst case is if we go through those shortage levels and Lake Mead continues to drop. At that point, the shortage sharing agreement no longer holds and it really would be up to the Secretary of the Interior as to who is going to get water out of that river. The modeling that Bureau of Reclamation has done would suggest that those reductions may need to be on the order of as much as 2 million acre feet to, if you look at climate change scenarios, maybe up to 6 million acre feet reduction, to maintain elevation 1000'.
