Is Nevada considering a proposal to restrict water use in Las Vegas?

By Austin Tannenbaum on 03/25/2023


A bill introduced in the Nevada Assembly last month would limit the water supply of single-family residences that receive their water from the Colorado River to half an acre-foot, or roughly 163,000 gallons per year. Southern Nevada gets nearly 90% of its water from the river.

The provision would apply when a federal declaration of a shortage on the Colorado River is in effect. Since one currently is, it would take effect immediately.

Households that exceed the limit would have their water shut off by the Southern Nevada Water Authority. Agency representatives said the threshold would only impact the top 20% of Las Vegas water users. The average customer in the Las Vegas Valley uses 130,000 gallons per year.

The Colorado River, which is used by Nevada and six other states, has been depleted by overuse, poor runoff conditions and prolonged drought accelerated by climate change.
