Butte Springs (Trego Hot Springs)

Butte Springs (Trego Hot Springs) was recorded at 187°F (86°C), which classifies as Scalding (above 113°F (45°C)). Dangerously hot: at or above 113°F, water can cause serious burns within seconds. Many springs this hot are vents, geysers, or boiling pools meant for viewing only — do not enter. That figure is the maximum surface temperature measured at the vent during the USGS/NOAA survey between 1965–1980 — not a current reading, and not the temperature of any pool downstream of the vent.

We can't tell you that, and at 187°F the question is largely settled by the temperature itself: this is above the 104°F ceiling health agencies recommend for hot water. At this temperature water can cause serious burns within seconds, and springs this hot are frequently vents or boiling pools meant for viewing only. Separately, this inventory records no information about land ownership, legal access, or whether a usable pool exists.

Butte Springs (Trego Hot Springs) is in Nevada at approximately 40.7700, -119.1130. The nearest graded lake is Squaw Creek Reservoir, about 22.4 miles away. Coordinates come from the USGS/NOAA inventory and locate the vent, not a trailhead or parking area.
