Hot Lake is a thermal site on Bureau of Land Management ground a few miles outside Oroville in Okanogan County, Washington. The record calls it a lake and gives it a hot reading, past the point where most people can sit in comfort. the access on record says open, and the land is public, managed out of the BLM's Spokane Wenatchee Field Office. Beyond that the record is quiet. No bath type is listed, and there is no fee or chemistry on file.

Location

Big Iron Road passes within a few hundred feet, so reaching the water is a short walk from wherever you leave the car. Elevation is under two thousand feet. This is the dry side of the state. The record shows under two feet of precipitation a year, with winter snow that never approaches the Cascade totals. Open public land, carrying a designation of PUB in the land data.

The months the record favors run December through February, and with snowfall this light a winter visit is workable. Camping on record is the Lost Lake group unit, roughly twenty-one miles away. At the temperature listed the water can scald. Check it with a hand before you commit a foot. No fee is mentioned anywhere in the record.

Heat Below
138 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 88% 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.
