Layer: Geothermal Potential (Permeability and Heat)
This layer represents modeled relative geothermal potential in Washington State. The color scale provides a ranking of potential for the presence of a moderate- to high-temperature geothermal resource; warmer colors indicate higher geothermal potential. The color scale is based on the combination of the heat potential and permeability potential models (Boschmann and others, 2013), and is intended to highlight areas of elevated potential for the presence of moderate- to high-temperature geothermal systems. The model is not meant to be used to locate areas for exploration on a site-specific basis, and should not be used at a scale greater than 1:250,000.
Importantly, this model represents geothermal resource potential without consideration for regulatory restrictions, land-management, or economic viability. See the companion report (Boschmann and others, 2013) for detailed discussion of modeling and results.
The raster dataset, including raster values, is also available in the downloadable data file [geothermal_potential_model] within the file geodatabase [geothermal_favorability.gdb].
