Horsley Draw Stock is a privately owned earth dam located in Sheridan, Wyoming, constructed in 1939 by designer Thomas D. Crank. The dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a height of 23 feet and a length of 300 feet, the dam has a normal storage capacity of 57 acre-feet and covers a surface area of 8 acres.

Despite its low hazard potential, the dam is currently in poor condition as assessed during the last inspection in September 2019. The dam has a moderate risk rating and a history of infrequent inspections every 5 years. The spillway type is uncontrolled with a width of 70 feet, and the dam is located on the Horsley Draw stream, with a drainage area of 2.6 square miles. The dam's purpose, location, and design make it an interesting case study for water resource and climate enthusiasts interested in earth dam structures and their management in Wyoming.

Overall, Horsley Draw Stock represents a unique example of a privately owned dam with multiple functions serving the local community. Its historical significance, design features, and current condition present opportunities for further research and monitoring to ensure its continued safety and effectiveness for fire protection, stock watering, and small fish pond management in the region.
