A HN comment [0] linked to a TucsonWeekly [1] piece about how Tucson used to be an oasis. Similarly, the Salt River used to run year-round through Phoenix. Las Vegas was an oasis too. Cattle and wells turned Tucson's river dry. The Salt River is blocked by dams, where most the water is used for plants and allowed to evaporate. Las Vegas' population vastly exceeds its natural water supply. I don't think the disappearance of these cities' oases can be blamed on "climate change".

The Israelis are experts in hydroponics, which uses a fraction of the water used for irrigation. This is a more responsible way to use water in an arid country.
If the problem causing these lakes to dry up is mostly "climate change", these people's predicaments are hopeless. But if the problem is mostly irresponsible use of the aquifers upstream from the lake, the problem is solvable.
