Planning for the worst: The Southern #Nevada #Water Authority seeks power to limit residential water use — The Las Vegas Review Journal #ColoradoRiver #COriver #aridification

The Las Vegas Wash is the primary channel through which the Las Vegas Valley’s excess water returns to Lake Mead. Contributing approximately 2 percent of the water in Lake Mead, the water flowing through the Wash consists of urban runoff, shallow groundwater, storm water and releases from the valley’s four water reclamation facilities.

While western states work to hash out a plan to save the crumbling Colorado River system, officials from Southern Nevada are preparing for the worst — including possible water restrictions in the state’s most populous county. The Nevada Legislature last week introduced Assembly Bill 220, an omnibus bill that comes from the minds of officials at the Southern Nevada Water Authority. Most significantly, the legislation gives the water authority the ability to impose hefty water restrictions on individual homes in Southern Nevada, where three-quarters of Nevada’s 3.2 million residents live and rely on the drought-stricken Colorado River for 90 percent of their water…

The bill, if approved and signed into law in its current form, would stand as another substantial step toward conserving Nevada’s tiny 1.8 percent share of the Colorado River, a river that has seen far less water in recent years than what current management plans allow to be taken out between the seven states that rely upon it for drinking water and agriculture irrigation…Under the bill’s current language, the water authority’s board of directors could limit residential water use to as little as 0.5 acre-feet per home annually, or about 163,000 gallons…

The average single-family home in Southern Nevada uses about 130,000 to 132,000 gallons annually, according to the water authority, meaning that such restrictions would be felt more by the valley’s larger residential water users…Such restrictions could be approved by the authority if the federal government declares water shortages in the Colorado River — which has been the case for each of the past two years, and projections for Lake Mead’s water levels show that shortage conditions likely will remain in place into the foreseeable future…

Bronson Mack, spokesman for the water authority, said the change would allow the agency to be more flexible and responsive in dealing with water shortage situations, especially if conditions along the river degrade to a point where the federal government was forced to impose restrictions across the entire basin and significantly limit water deliveries.
