Kelly Dam, located in the picturesque area of ARVADA, Wyoming, is a private irrigation structure built in 1973 along Kelly Creek. Designed by Marvin E Young, this earth dam stands at a height of 26 feet and has a storage capacity of 109 acre-feet. Despite its significant hazard potential and poor condition assessment, it serves multiple purposes including fire protection, stock watering, and irrigation.

The dam, with a spillway width of 150 feet, is regulated by the State Engineer's Office and undergoes regular inspections. However, with a risk assessment rating of moderate, there is a need for improved risk management measures. The surrounding area, part of Johnson County, Wyoming, enjoys the benefits of the dam's surface area of 11 acres and drainage area, though maximum discharge capacity is currently listed as zero.

Kelly Dam's location in the Omaha District underlines its importance for water resource management in the region. As a focal point for water enthusiasts and climate advocates, the dam's history, design, and ongoing maintenance offer valuable insights into the challenges and opportunities of managing water resources in the face of changing climate conditions.
