Borax Hot Springs is a unique geological phenomenon, featuring geothermal springs that range in temperature from 104 to 300°F and are part of an active fault line. Due to its boiling temperature, Borax Hot Springs is NOT suitable for soaking! The nearby 10-acre Borax Lake, created by these powerful hot springs, is owned by The Nature Conservancy and contains high concentrations of sodium borate, arsenic, and lead, making it an ecologically sensitive area that supports unique microbes and the endangered Borax Lake chub.

This little reservoir had some nice water in June 2024. If you need some, better get it from here than from Riddle Reservoir which is very shallow and muddy to get to.
