Ninemile Springs flows at 79°F in Humboldt County at 4,395 feet elevation, emerging 27 degrees above the 52°F average annual air temperature near Winnemucca. The spring sits 235 feet from Ninemile Road, requiring a short walk to access. Recent USGS measurements documented water at 79°F with balanced chemistry showing calcium at 25 milligrams per liter, sodium at 27 milligrams per liter, sulfate at 20, and chloride at 22.

The spring emerges in the sagebrush and grassland terrain north of Winnemucca at 4,395 feet elevation, in country characterized by broad valleys and scattered low ranges typical of north-central Nevada. The area receives just 10.3 inches of annual precipitation and 26.3 inches of snow, creating one of the state's drier climates. The spring's name likely derives from its distance from a historical reference point, following the common western practice of naming features by their mileage from towns or trail junctions.

History of Ninemile Springs

Documentation of Ninemile Springs' historical use remains sparse. The spring exists in country that supported ranching operations from the late 1800s onward, and the feature likely served as a reliable water source for livestock in this arid region. The balanced mineral content suggests the water circulates through mixed volcanic and sedimentary rock without encountering highly mineralized zones. No records of resort development or intensive recreational use have been located.

Access requires a 235-foot walk from Ninemile Road across open terrain. The spring's 79°F temperature makes it marginally warm for bathing during cold weather but less appealing in summer heat. Spring and fall provide the most comfortable visiting conditions. No developed camping exists in the immediate vicinity. Visitors should be prepared for remote conditions, carry adequate water, and inform others of their plans when visiting this isolated feature in north-central Nevada.
