Muddy Spring
Muddy Spring flows at 90 degrees Fahrenheit in Clark County at 1,770 feet elevation near Moapa Town, emerging 21 degrees above the 69-degree desert air temperature. Located just 84 feet from the nearest road, the spring offers roadside access to warm waters in the Mojave Desert. The spring's name references the Muddy River, which drains thermal springs throughout the Moapa Valley before flowing to the Colorado River system.
The spring occupies low desert terrain in southern Nevada's arid valleys, surrounded by creosote bush, scattered desert scrub, and sandy washes at elevations below 2,000 feet. The Moapa Valley forms a broad lowland where warm springs feed perennial streams supporting riparian vegetation, a stark contrast to surrounding desert landscapes. The Muddy Mountains rise eastward while the Mormon Mountains extend to the north. Annual precipitation totals just 6 inches with minimal snowfall, creating one of Nevada's hottest environments with summer temperatures regularly exceeding 100 degrees.
The Muddy River and associated springs sustained Indigenous Paiute populations for thousands of years, providing reliable water in the harsh desert environment. Euro-American explorers traveling between Utah and California encountered the valley in the mid-19th century, with Mormon settlers establishing communities dependent on the perennial water sources. The warm springs feeding the Muddy River system continue flowing despite increasing groundwater pumping and development throughout the valley. Current conditions show ongoing thermal discharge maintaining the river's year-round flow.
Visit October through April when desert temperatures are moderate; summer heat exceeds 100 degrees regularly, making outdoor activity dangerous. The 90-degree water temperature provides comfortable bathing without excessive cooling. Roadside access eliminates hiking requirements, though permission may be needed depending on specific land status. Moapa Town offers limited services; Las Vegas lies 60 miles south. The warm springs support unique aquatic species requiring protection from disturbance.
