There are 3 sources that I know where the water is coming from, plus precipitation. One is from Canedlas X fumeroles, the others about 20km's south east close to where the Rio Los Patos start & the other is from the North Rim of Cerro Galan near where Aguas Calientes starts. Where the fault lines are there could be activity also.
