Initial reservoir temperatures estimated by use of chemical geothermometers for thermal waters in southeastern Idaho generally result in poor agreement between the sodium-potassium-calcium and silica geothermometers. Concentrations of magnesium in these thermal waters ranged from 7.1 to 260 milligrams per liter. By applying a magnesium correction to the sodium-potassium-calcium geothermometer, estimated reservoir temperatures previously reported are reduced between 39/sup 0/ and 268/sup 0/C and result in much closer agreement between the sodium-potassium-calcium- and silica-estimated reservoir temperatures. Reservoir temperatures in southeastern Idaho probably do not exceed 128/sup 0/C.
