Williams Fork Reservoir plays an important role in water conservation, while being an asset in revealing archaeological data of earlier existent peoples in the region. The reservoir is located about 12 miles southeast of Kremmling at an elevation of 7874 ft. in Grand County, Colorado, near the center of Middle Park. Williams Fork is a tributary of the Colorado River, extending from Clear Creek to Vasquez Creek, with the Vasquez Tunnel running through and its completion in 1959.
Williams Fork is a water source to the Denver Metro Area, with diverted water from high elevation tributaries of the Williams Fork River to the Gumlick Tunnel for departure to the Moffat Tunnel system. Standing 217 feet above the Williams Fork River streambed, the dam backs up a reservoir of 97,000 acre feet of water.
Williams Fork is also a Paleo-Indian site. Archaeologists believe that 12,000 years ago, during the last Ice Age, people migrated from Asia into North America. Most Paleo-Indian sites are identified by an existence of projectile points. The Williams Fork Reservoir was dominated by James Allen projectile points, a categorized set of points, or better known as a categorized set of stone tools. The reservoir allows archaeologists to access the extent in which the James Allen points and perhaps earlier existent groups were bestowing the mountains during the Holocene period, the name given to the last 10,000 years of the Earth's history.
