Klamath Falls, Oregon, is located in a Known Geothermal Resource Area which has been used by residents, principally to obtain hot water for space heating, at least since the turn of the century. Approximately 400 shallow-depth wells ranging from 27 to 580 m in depth are used to heat approximately 500 structures.
