A bstract An integrated exploration study is presented to locate low‐temperature geothermal reservoirs in the Honey Lake area of northern California. Regional studies to locate the geothermal resources included gravity, infra‐red, water‐temperature, and water‐quality analyses. Five anomalies were mapped from resistivity surveys. Additional study of three anomalies by temperature‐gradient and seismic methods was undertaken to define structure and potential of the geothermal resource. The gravity data show a graben structure in the area. Seismic reflection data indicate faults associated with surface‐resistivity and temperature‐gradient data. The data support the interpretation that the shallow reservoirs are replenished along the fault zones by deeply circulating heated meteoric waters.
