Indian Springs
Indian Springs in Power County flows at 90 degrees near American Falls at 4,500 feet elevation, offering one of southeastern Idaho's more accessible thermal experiences just 150 yards from Indian Springs Road. Its near-neutral pH of 7.5 and high chloride content of 220 mg/L set it apart chemically from the alkaline springs that dominate the Snake River Plain.
The spring sits in the agricultural corridor along the Snake River, where irrigated farmland meets the sagebrush-covered benchlands above. Pipeline Campground is less than two miles away on the river below American Falls Dam, with boat ramps and fishing access. The area receives about 15.5 inches of rain and 37 inches of snow annually. The 90-degree water is warm enough to feel distinctly thermal but cool enough for comfortable, extended immersion on all but the hottest summer days.
The unusually high chloride and elevated calcium and magnesium concentrations suggest this spring taps a different aquifer system than the sodium-dominated volcanic springs to the west. The chemistry points to dissolution of sedimentary evaporite deposits, possibly Paleozoic limestones and associated formations beneath the Snake River Plain basalts. At 32 degrees Celsius, the moderate temperature indicates a shallower circulation path or significant groundwater mixing.
The spring is a short walk from Indian Springs Road and open to visitors. Water temperature is comfortable for soaking without the scald risk of hotter Idaho springs. Pipeline Campground sits just 2.9 kilometers away with six first-come, first-served sites, vault toilets, picnic tables, and Snake River fishing access. No reservation system is in place. Pack out all trash as no dumpsters are provided.
