Dagger Creek Hot Spring
Hotter than recommended
At 110°F this is above the 104°F ceiling the CDC and CPSC recommend for hot water. Overheating and burns are a real risk. Test the water and keep exposure short, if you enter at all.
What this number is, and is not
110°F is the maximum surface temperature measured at the vent during the USGS/NOAA thermal springs survey (1965–1980). It is not a current reading, and the temperature of any pool downstream of a vent is almost always lower.
This page also records nothing about access. Land ownership, legal entry, trail conditions, and whether a usable pool exists are all outside this dataset. Confirm with the managing agency before setting out.

Frequently Asked Questions
Dagger Creek Hot Spring was recorded at 110°F (43°C), which classifies as Hot (104–113°F (40–45°C)). Hotter than the 104°F limit health agencies recommend — too hot for many people, with a real risk of overheating and burns. Test the water and keep exposure short, if you enter at all. 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 110°F the question is largely settled by the temperature itself: this is above the 104°F ceiling health agencies recommend for hot water. Overheating and burns are a real risk at this temperature. Separately, this inventory records no information about land ownership, legal access, or whether a usable pool exists.
Dagger Creek Hot Spring is in Idaho at approximately 44.5160, -115.2950. The nearest graded lake is Deadwood Reservoir, about 23.1 miles away. Coordinates come from the USGS/NOAA inventory and locate the vent, not a trailhead or parking area.
