I just overnighted at Mill Creek CG, 24 miles south of Battle Mountain. Free. Year-around creek. No hot springs that I know of. Tables. Pit toilets. Fire rings. BBQs. Trash cans. No water. Nice ranger who says it's rarely used. In Mill Creek Recreation Area. About 3-4 miles off of 305 on maintained gravel road. Two bars of Verizon 3g, without booster. Would definitely stay here again.
