Warm Springs Natural Area, Protected natural area in Clark County, Nevada.

Warm Springs Natural Area covers 1,179 acres near the Moapa Indian Reservation in Clark County, Nevada, at 2,123 feet. Close to 24 warm springs feed the headwaters of the Muddy River, and California fan palms grow around the water, an ecosystem otherwise limited to the low Colorado Desert. The Southern Nevada Water Authority owns the land, which has trails and exhibits.

Howard Hughes bought the 1,218-acre ranch in 1968. The LDS Church acquired most of it in 1978, tried cattle grazing, then sold most of the land and kept 75 acres as the Warm Springs Recreational Ranch. The Southern Nevada Water Authority bought 1,220 acres in 2007 to protect the Muddy River headwaters and the Moapa dace. A fire on 1 July 2010 destroyed the original ranch house; the rebuilt LDS facility reopened in June 2017.

The springs feed the Muddy River and support the Moapa dace, a critically endangered fish found nowhere else. The Moapa Band of Paiutes live on the adjacent reservation, and the LDS Church's Warm Springs Recreational Ranch remains a private multi-use area for members.

The 1,220 acres acquired by the Southern Nevada Water Authority in 2007 are open as a public nature area with trails and exhibits; the Moapa Valley National Wildlife Refuge within it covers 106 acres. The springs lie near the Moapa Indian Reservation in Clark County, at 2,123 feet (647 m). Expect desert heat and carry water.

The springs are the headwaters of the Muddy River, and the adjacent Moapa Valley National Wildlife Refuge, a 106-acre unit, protects the critically endangered Moapa dace, a small fish found nowhere else. Non-native fish and habitat loss have driven its decline.
