After a detailed – and dire – technical presentation from one of her experts, the commissioner of the U.S. Bureau of Reclamation on Thursday told an audience of water stakeholders that officials weren’t trying to scare people, only make plain the risks of historically low levels on Lake Mead.

The plan identifies earlier, steeper cuts to water users than those mandated by a 2007 agreement to decrease the risk of a rapid decline in lake level.
