Several geothermal occurrences in the state of Idaho were examined for their potential for electrical generation and direct use. Five sites were studied in detail with respect to their current conditions and developments, and the potential for future power generation projects: Crane Creek Hot Springs, Raft River, Big Creek Hot Springs, Vulcan Hot Springs KGRA, and the Magic Reservoir Hot Spring area. From this evaluation, Crane Creek Hot Springs was determined to be the best prospect for future development, in light of the current state of private-sector development at the Raft River site. The Vulcan KGRA and Big Creek Hot Springs are considered to be low priority candidates for electrical generation because of their remote locations and other conditions. Additional hydrogeologic information is needed for the Magic Reservoir area to determine the feasibility of a project in this area
