It's time to get real!

Tier two water shortage declared

A water shortage on the Colorado River means it's more important than ever to conserve water. From Sept. 1 through Oct. 31, mandatory fall watering restrictions limit landscape irrigation to three assigned days per week. As always, sprinkler watering on Sundays is prohibited. Change your watering clock now. It's the law! 

Find Your Watering Days

As a result of shortage conditions on the Colorado River, the federal government announced a tier two water reduction, limiting the amount of water Southern Nevada will be allowed to withdraw from Lake Mead beginning in January 2023.

What you can do to conserve

Drought and climate change have caused Lake Mead to drop about 170 feet. The federal government has issued a tier two water shortage declaration, reducing the amount of water Southern Nevada is allowed to draw from the lake. We're asking everyone to help protect and extend our community's primary water supply.

Our community loses billions of gallons each year due to overwatering, and too much water is harmful to turf, trees and shrubs.

Follow the mandatory seasonal watering restrictions to save water, improve the health of your landscape and avoid water waste fines.

New rules protect our limited water supply

Southern Nevada's water supply situation is changing, and the rules are too. Stay in the know.

Recent legislation prohibits the use of Colorado River water to irrigate nonfunctional turf

A new law requires nonfunctional grass to be removed by the end of 2026. This initiative will save our community an estimated 9.6 billion gallons of water per year. The law does not apply to grass in a homeowner's yard. From tips and tools to rebates and resources, we're happy to help.

Code changes to limit residential pool sizes

Ongoing drought and climate change conditions continue to affect water levels in Lake Mead – Southern Nevada's primary water supply. As a result, the federal government declared a shortage on the Colorado River, reducing Southern Nevada's available water supply by 7 billion gallons, and additional reductions are expected in the coming years.

To help manage these water supply constraints, the Southern Nevada Water Authority is working with local jurisdictions to modify building and development codes to limit the surface area of new residential swimming pools and spas to no more than 600 square feet per property.
