Hardboard Spring is a USGS thermal point on the edge of Klamath Falls, Klamath County, Oregon, three miles out. The water is only a little above room temperature. The record has no owner and no public access status for it, so check before treating it as open. Beyond the temperature and a site number, the file holds almost nothing.

Location
19 miles from Klamath Falls, OR

Roughly a hundred feet off an unnamed road. Mid elevation, dry, with moderate winter snow. Topsy Campground is about thirteen miles away, and no land unit or designation is attached to the spring, which for a spot this close to town points toward private or municipal ground rather than public land, though that is a guess the record cannot confirm.

Winter is on file as the best time. Not a soaking spring at this temperature. With nothing recorded about access or ownership, assume you need permission. The USGS temperature has no date attached, and there is no water chemistry to go with it.

Heat Below
79 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 13% 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.
