Pat Mulroy, the long-time head of the Southern Nevada Water Authority, announced her plans to retire this week. She’s been a strong proponent of the plan to pump groundwater from the Great Basin to Las Vegas. But she also suggested in an interview with the Las Vegas Sun that the project wouldn’t be necessary if Nevada could work out a deal with states such as Utah that hold water rights on the Colorado River.
The new study in the Journal of the American Water Resources Association estimates about 380,000 acre-feet of water a year is lost when it soaks into the lake's sandstone banks each year. That’s more than the state of Nevada is entitled to take from the river under a 1922 interstate compact.
The two biggest reservoirs on the Colorado River, Lake Mead and Lake Powell, are both under 50-percent of their capacity.

U.S. Secretary of the Interior Ken Salazar is expected to make an appearance just south of Utah’s border at Glen Canyon Dam Monday.

Many other countries have the same concern. Their representatives got a close-up look last week at how the United States is handling that project.
