The Geysers-Clear Lake area is one of two places in the world where major vapor-dominated hydrothermal reservoirs are commercially exploited for electric power production. Because energy can be extracted more efficiently from steam than from hot water, vapor-dominated systems are preferable for electric power generation, although most geothermal electric power facilities tap water-dominated systems. The Geysers- Clear Lake geothermal system has therefore been of great interest to the geothermal industry.

This collection of 59 short papers on subjects in the fields of geology, hydrology, topography, and related sciences is one of a, series to be relea~ed during the year as chapters of Professional Paper 450. The papers in this chapter report on the scientific and economic· results of current work by members of the Geologic, Topographic, and 'Vater Resources Division of the United States Geological Survey. Some of the pa.pers annom1ce new discoveries or present observations on problems of limited scope; other papers draw conclusions from more extensive or continuing investigations that in large part will be discussed in greater detail in reports to be published in the future.
