Grayson County is part of the [[Western Coal Field]] region of [[Kentucky]]. Only the western third of the county has coal; the rest lies in the Clifty Area, which has similar sandstone bedrock, some of it is bituminous but never commercially exploited as tar sands or rock asphalt. The county lies in the Rough Creek Fault System, considered a potential hydrocarbon resource.<ref>{{Cite web |title=Rough Creek Graben |url=http://www.uky.edu/KGS/emsweb/rcg/rcgstudy.html}}</ref>

Grayson County is home to two [[U.S. Army Corps of Engineers]] lakes, [[Rough River Lake]] on the northern border of the county and [[Nolin River Lake]] on the southeast border. The lakes attract many tourists and have led to the use of "Twin Lakes" to identify some businesses and institutions, such as the Owensboro Health Twin Lakes Medical Center in Leitchfield.
