Unnamed Thermal Spring
Near Burns at 3,520 feet on Bureau of Reclamation land at Warm Springs Reservoir, this spring produces scalding 144°F water, creating a 91.6°F temperature differential above the 52.4°F ambient air. Recent USGS measurements recorded 15°C in associated waters—likely cooled discharge rather than source temperature. The water shows pH 8.2 and moderately alkaline chemistry.
The spring emerges in the impounded landscape created by Warm Springs Dam on the South Fork Malheur River. At this elevation, the reservoir sits in a transition zone between sagebrush flats and juniper-covered slopes, with volcanic bedrock underlying sedimentary valley fill. Annual precipitation of 12 inches and 26.1 inches of snow supports typical high desert vegetation, while the reservoir creates localized habitat for waterfowl and fish. The site sits 1,250 meters from the nearest road, requiring a moderate walk across Bureau of Reclamation lands.
Warm Springs Reservoir was constructed by the Bureau of Reclamation in the early 20th century as part of the broader effort to develop irrigation infrastructure in the Malheur River drainage. The thermal spring predates the reservoir but now emerges within the recreation area managed around the impoundment. Historical documentation of the spring's pre-dam character is absent.
Access the spring via walk from reservoir access roads; verify current Bureau of Reclamation regulations. The 144°F temperature prohibits direct contact without extensive cooling. Visit spring through fall; winter access depends on snow and ice conditions. Chukar Park Campground along the North Fork Malheur River, 19.1 km distant, provides developed camping. The reservoir supports fishing and boating recreation. Respect all posted closures around dam infrastructure.

Let the sounds of the babbling North Fork of the Malheur River lull you to sleep at one of the riverside campsites of Chukar Park Campground. This primitive facility offers 19 campsites, seven of which are situated along the shady, lush riparian vegetation. Popular as a base camp with birders, hunters and fishers as well as those venturing through along nearby highway 20, Chukar Park has campsites with partial shade and in full sun.
