Jones #1 is a historic earth dam located in Kremmling, Colorado, along the Sheep Creek-TR river. Built in 1879 for water supply purposes, this dam stands at 27 feet high and spans 340 feet in length, with a storage capacity of 295 acre-feet. It serves multiple functions including fire protection, stock watering, irrigation, and small fish pond maintenance, making it a crucial resource for the local community.

Despite its age, Jones #1 is in satisfactory condition according to its last inspection in September 2018, with a significant hazard potential due to its location and structural design. The dam features an uncontrolled spillway and a slide gate outlet, demonstrating its historical significance and engineering ingenuity. With a moderate risk assessment rating and regular inspection schedule, Jones #1 remains a vital water infrastructure asset in Grand County, Colorado, highlighting the importance of maintaining and monitoring aging dams for water resource and climate enthusiasts.
