This is just a business decision to go after Mammoth's meager water use. No regard to history or public relations. The amount of water involved is so small that if appears LADWP is just trying to send a message again. They might as well just put up billboards - it would be cheaper than legal fees. The billboards could repeat what one LADWP manager said publicly, "we own the people of Owens Valley, lock stock and barrel." Keep the message simply and consistent.
