A warm spring in the Lake County hills, Bad Creek Spring sits a bit over three miles from Cobb. Tepid is the honest word for the temperature on record, water you notice is warm without wanting to stay in long. Who owns the land and whether the public may visit are both blank in the record, which is the main thing to know before planning around it.

Location

Big Canyon Road comes within about four hundred feet, a short walk from whatever surface that road has. Elevation is modest, under seventeen hundred feet. Winters here are wet and mostly snowless, a couple of inches a year, and the yearly average temperature is mild. Nothing ties this spring to a land unit, so there is no ranger district or park office to call.

The record favors the three winter months, when tepid water feels warmest against cool air. For camping the record gives Warm Springs Rec Area, twenty miles off. Nothing confirms public access, so assume the ground could be private until you have checked. Nobody has noted a fee.

Heat Below
156 milliwatts per square meter of heat flow

That's about 2½ times the US average of 65. It's higher than at 95% 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.
