Weiser Warm Springs is a tepid spring in Washington County, Idaho, about five miles out from the town of Weiser. The USGS logs it as a thermal point and measured the flow at a trickle, a few hundredths of a cubic foot per second. Water at this temperature feels cooler than your skin on a summer afternoon. Public access is not on record, and the record is empty.

Location

It sits low in dry country, the kind of Idaho that sees about a foot of rain a year and a light dusting of snow by mountain standards. The spring is a roadside stop. Under two hundred feet separate it from the nearest road, though that road has no name in our records.

Winter is the listed season, December through February. The few steps from the road are the easy part. What you cannot check from here is ownership, because nothing was filed, and the same goes for permission to visit. The chemistry dates to a sample taken in 1973, so treat the temperature as historical. Mann Creek Campground is the closest camping, roughly ten miles away.

Heat Below
90 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 31% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
