We have made a revised estimate of the recoverable thermal energy in the Salton Sea known Geothermal Resource Area (KGRA) using the strong correlation between the temperature distribution and the magnetic anomaly. Our estimates of the power-generating potential range from 1300 MW-20 years (for indicated resources) to 8700 MW-20 years (for hypothetical resources). These figures are compatible with previously published estimates. Comparison of various estimation procedures reveals major differences in techniques used to assess reservoir volume. However, authors agree generally on parameters Used to convert reservoir volume to recoverable energy. Our conservative estimates justify continued research and development to solve the technical problems that stand in the way of commercialization of the Salton Sea resource
