Stockpond, located in Antelope Coal Mine, Campbell County, Wyoming, serves multiple purposes such as flood risk reduction, fire protection, and as a stock or small fish pond. Constructed in 2007, this earth dam stands at a height of 28 feet with a hydraulic height of 20 feet, providing a storage capacity of 165 acre-feet. With a surface area of 12 acres and a drainage area of 1 square mile, Stockpond plays a vital role in managing water resources in the region.

Managed by a private owner, Stockpond is regulated by the State of Wyoming with oversight from the State Engineer's Office and Department of Environmental Quality. The dam's condition assessment in 2017 rated it as fair with a low hazard potential. Despite its moderate risk level, Stockpond has a history of meeting inspection and enforcement requirements, ensuring its structural integrity and safety. With Liz Cheney as the Congressional Representative for the area, Stockpond remains a key asset for water storage and flood mitigation efforts in the region.

Incorporating stone core types and soil foundations, Stockpond's uncontrolled spillway and other controlled outlet gates help manage water discharge effectively. The dam's last inspection in July 2017 revealed its operational adequacy with a prescribed frequency of every 5 years. As an essential infrastructure for water management and conservation, Stockpond serves as a testament to sustainable water resource practices while addressing the challenges of climate change in Wyoming's arid landscape.
