Description: This point feature class includes location and information regarding open loop (heat exchange) geothermal systems throughout Washington State. Point location data and attributes (water right number, well owner name, priority date, purpose, withdrawal rate, yearly volume, and latitude/longitude) were obtained from the Washington Department of Ecology. There is a related table associated with this feature class that provides a list with associated URLs of water right supporting documents (application, permit, certificate, and well log).

Description: This point feature class includes location and information regarding vertical closed loop geothermal systems throughout Washington State. Point location data and attributes (for example, Notice of Intent ID, well owner name, well log ID, latitude/longitude) were obtained from the Washington Department of Ecology. There is a related table associated with this feature class that provides further details (for example, well depth, well diameter, and well completion date) regarding each well drilled for a single closed loop system.
Description: This point feature class consists of information relating to cold, thermal and/or mineral springs as well as fumaroles within Washington State. These data were compiled as part of a Department of Energy geothermal grant, and supersede previously released spring feature classes by the Washington State Division of Geology and Earth Resources. These data are included in a file geodatabase that also incorporates water chemistry, temperature, and photographic data for springs found in this feature class.

Description: This dataset consists of all permitted geothermal test holes on record with the Washington State Department of Natural Resources, Washington Geological Survey, the permitting agency for geothermal exploratory holes in Washington State. Several of these permitted boreholes have never been drilled, and others may be pending permits; by law, any gradient or heat flow information may not be disclosed earlier than one year following hole abandonment. This feature class is part of a geodatabase that contains statewide geothermal data for Washington State.

Description: This dataset contains information on the location, heat characteristics, and availability of water chemistry of known geothermal and heat flow wells in the state of Washington. The data were collected from databases compiled by the Washington State Department of Natural Resources (DNR), Washington Geological Survey (WGS) and Southern Methodist University (SMU) (Blackwell, 2010), as well as new temperature-gradient data collected as part of the National Geothermal Data System (NGDS). Chemical analyses and scanned geophysical logs are available for some of these wells through related data tables. In addition, temperature-depth plots are available for many boreholes. Much of the data is located within central and eastern Washington.

Description: This dataset contains information on the location, heat characteristics, and availability of water chemistry of known water wells in the state of Washington. This version is intended to supersede, in part, the geothermal_locations point feature class in the previously released Geothermal Resources geodatabase (Washington Division of Geology and Earth Resources, 2010). This dataset includes borehole and water well temperature information obtained from the Washington State Department of Ecology (ECY), Washington Division of Geology and Earth Resources Open File Report 94-11 (OFR 94-11), Southern Methodist University (SMU) Regional Heat Flow Database, and the U.S. Geological Survey. We also include unpublished data on file with the Division. Data from these sources were incorporated into this database only if a calculated gradient or an assumed bottom-hole temperature were recorded. We use the term 'assumed' to denote that the location of the temperature measurement within the borehole is assumed to be the bottom, although this is generally unknown; temperatures from this dataset should be considered mininum bottom-hole temperatures. This feature class is part of a geodatabase that contains geothermal data for Washington State. Chemical analyses are available for some of these locations in a related table within the same file geodatabase. Much of the data is located within central and eastern Washington.

Name: Geothermal Potential (Permeability and Heat)
Display Field:
Type: Raster Layer
Geometry Type: null
Description: This raster dataset represents modeled relative geothermal potential in Washington State. The values provide a ranking of potential for the presence of a moderate-to-high temperature geothermal resource. The raster values are based on the combination of the heat potential and permeability potential models. The model is intended to highlight areas of elevated potential for the presence of moderate-to-high temperature geothermal systems. See the companion report (Boschmann and others, 2014) for detailed discussion of modeling and results.
Description: This raster dataset represents relative geothermal favorability in Washington State. The values provide a ranking of favorability for exploration and development of moderate-to-high temperature geothermal resources. The raster values are based on weighted raster overlay layers, including: (1) modeled geothermal potential; (2) proximity to transmission lines, and (3) elevation restrictions. See the companion report (Boschmann and others, 2014) for detailed discussion of modeling and results.
