Coyote Spring
Coyote Spring in Millard County flows at 82°F on BLM land near Delta, delivering water with elevated salinity including 380 mg/L sodium, 340 mg/L sulfate, and 470 mg/L chloride at 4,420 feet elevation.
Situated in Utah's west-central desert basin country managed by the BLM Fillmore Field Office, the spring emerges in extremely arid terrain receiving only 6 inches of annual precipitation with minimal 14.8 inches of snow. The landscape features sagebrush and shadscale communities adapted to severe aridity, with playas and ancient lake beds visible across the basin floor. Distant mountain ranges provide the only relief in this expansive, open country. The spring lies 159 meters from Coyote Spring Road, reflecting its local significance for navigation and occasional water use.
Named for the abundant coyote population in this desert region, this spring appears in early Bureau of Land Management surveys and grazing assessments. The Delta area saw homesteading attempts and ranching activity beginning in the early 20th century, and such perennial springs were critical livestock water sources in this parched landscape. The spring remains undeveloped on public lands.
Open access on BLM land allows year-round visitation, though summer temperatures regularly exceed 100°F and winter can bring subfreezing conditions. The warm but highly mineralized water is not suitable for drinking without treatment. No facilities exist at the site. Bring all water, shade, and supplies. The extreme aridity and heat make spring and fall the practical visiting seasons for those studying desert thermal systems in western Utah.
