Groundwater

Red Rock Mountains

The Southern Nevada Water Authority (SNWA) has acquired and continues to develop a significant number of in-state groundwater resources. These groundwater resources are intended to provide Southern Nevada with a more balanced mix of Colorado River and non-Colorado River water than currently exists.

In addition to existing water provider groundwater rights in the Las Vegas Valley, SNWA has a number of other groundwater permits and applications in southern and eastern Nevada.

Many of these rights and applications stem from filings made by the Las Vegas Valley Water District in 1989, but others are the result of specific SNWA efforts that were initiated in the mid to late 1990s.

Currently, Southern Nevada gets about 10 percent of its water supply from groundwater resources.

Groundwater resources include:

• Las Vegas Valley Groundwater
• In-state Groundwater Resources
• Garnet and Hidden Valleys
• California Wash Basin
• Three Lakes Valley and Tikaboo Valley
• Indian Springs
• Coyote Spring Valley
• Spring Valley
• Delmar, Dry Lake and Cave Valleys
• Snake Valley
