Little King Ranch, also known as Kings Reservoir, is a privately owned water structure located in Hot Sulphur Springs, Colorado. Managed by the Ken R. White Company, this earth-type dam was completed in 1968 and stands at a height of 57 feet, with a storage capacity of 1,570 acre-feet. The dam serves primarily for recreational purposes and is regulated by the Colorado Department of Water Resources, with inspections conducted regularly to ensure its safety and compliance with state regulations.

Situated on Buffalo Creek in Grand County, Colorado, Little King Ranch covers an area of 52 acres and has a drainage area of 2 square miles. Despite its significant hazard potential and unsatisfactory condition assessment, the dam has an uncontrolled spillway and a maximum discharge of 1,030 cubic feet per second. The emergency action plan for the structure was last revised in 1996, and the risk assessment categorizes it as moderate. With a history dating back over five decades, this dam continues to be a focal point for water resource and climate enthusiasts interested in its operational and safety measures.
