Warm Springs Natural Area

Located near the town of Moapa, the Warm Springs Natural Area contains more than two dozen springs, which form the headwaters of the Muddy River.

Formerly known as the Warm Springs Ranch, the 1,220-acre property provides habitat for several sensitive species. For many years prior to the Southern Nevada Water Authority's involvement, the U.S. Fish & Wildlife Service considered this property a top priority in Southern Nevada for acquisition and protection.

Why the Warm Springs Natural Area is important

In 2007, the Water Authority purchased the property to protect the headwaters of the Muddy River and the habitat of the endangered Moapa dace with funding from the Southern Nevada Public Land Management Act. The terms of the act require a commitment to manage the property as a natural area.

A Stewardship Plan was developed for the Warm Springs Natural Area in coordination with the U.S. Fish and Wildlife Service, The Nature Conservancy, Nevada Department of Wildlife, the signatories of the 2006 Memorandum of Agreement, and other stakeholders. The Warm Springs Natural Area opened to the public in December 2017.

Primary reasons for acquisition of the Warm Springs Natural Area:

  • Manage our water resources in the Muddy River and Coyote Spring Valley
  • Protect the habitat of the endangered Moapa dace
  • Protect the headwaters of the Muddy River where we own and lease water rights
  • Advance our goal of fostering responsible environmental stewardship

Gone fishing, sort of

In addition to being the home of the endangered Moapa dace fish, the Warm Springs Natural Area is also one of the best kept secrets in Southern Nevada.

Sensitive species

The Warm Springs Natural Area is home to 28 sensitive species, more than 200 species of birds, and a wide variety of other species.

  • Most of the entire world's population of Moapa dace reside in the Moapa Valley National Wildlife Refuge and the Warm Springs Natural Area. The Moapa dace is protected by the Endangered Species Act, and the U.S. Fish and Wildlife Service (USFWS) considers the recovery of the Moapa dace to be essential in this region.
