This coverage (vector polygon file) shows the area of significant
lateral extent favorable for discovery and development of local
sources of low-temperature (90°C and above) water. Areas are
defined on the basis of thermal springs, wells, and geohydrologic
settings generally favorable for recovery of thermal water.
Existing knowledge does not in general permit the inference that
thermal water may be found everywhere within the depicted areas,
nor do the boundaries represent certain knowledge of the areal
extend of the geothermal systems. KGRAs were derived from
Classification of Public Land Valuable for Geothermal Steam and
Associated Geothermal Resources, U.S. Geologic Survey Circular 647
(1971), but the source of the geospatial coverage is unknown and
provided here "as is." It is not complete and as such, it
will continue to undergo review, revision, or possibly eliminated.
The Geothermal Resources Information Layer for
Oregon - Release 1 (GTILO - Release 1) is a geospatial database
system that stores and manages Oregon's existing geothermal
resource information. The compilation of this data is the latest
effort by the Oregon Department of Geology and Mineral Industries
to provide visual and historical data of Oregon's geothermal
systems. The data sets are hot and warm springs, geothermal
prospect wells, geothermal wells, and low-temperature well, which
provide a framework for regional spatial analysis. The power of GIS
(geographic information system format) facilitates easy access to
the database and analysis for development and exploration purposes.
Data sets for Known Geothermal Resource Areas and Direct-Use
Application areas are included as ancillary information. A
centralized database for the geothermal data in Oregon provides a
powerful tool that the geothermal industry can use to reevaluate
earlier geothermal exploration efforts and develop new approaches
that may find hidden geothermal resources in the state.
