At 187°F, the source water at Patua Hot Springs (Fernley) is hot enough to cause burns. Some hot springs this hot have cooler side pools or downstream areas suitable for soaking. Always test the water temperature before entering.

Patua Hot Springs sits on BLM land near Fernley in Lyon County, five miles or so from town, and its water is hot enough to cook with. Public access is open. It is roadside. The Sierra Front Field Office manages the ground. A 1988 sample showed heavily mineralized water, over two thousand parts per million of dissolved solids, with iron among the minerals.

Location

The closest road runs under 150 feet away and goes unnamed on the record. Mid-elevation basin near Fernley, dry, with seven inches of precipitation and under a foot of snow in most years. Public BLM land with no special designation. Summers are warm and the yearly average lands in the high fifties.

The source will burn you. Test downstream water carefully before you go anywhere near it. Winter months are listed as best. No campground or fee on file. The chemistry reading is from the late 1980s, and the heavy mineral content it showed is worth knowing if you have any thought of contact with the water.

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 30% 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.
