Location
20 miles from Clearlake Oaks, CA

Lake County lowland, wet in winter with a dusting of snow some years. Harbor Road is the road in question, and the spring sits only a short way off it. There is no land unit or fee on file, and the owner is unrecorded. A photo exists for this spring, which helps a little with knowing what to expect.

The listing points to winter. Warm Springs Rec Area, the campground on record, is over twenty miles out, so this is more of a day stop. The water sits in the low nineties and is safe. Confirm ownership before you go; nothing on file says the public may visit.

Heat Below
175 milliwatts per square meter of heat flow

That's about 2½ times the US average of 65. It's higher than at 98% 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.
