G. H. Reservoir, located in Carbon, Wyoming, is a private water storage facility primarily used for fire protection, stock, and as a small fish pond. Built in 1977, this earth dam stands at a height of 17 feet and has a hydraulic height of 12 feet, with a capacity to hold 165 acre-feet of water in its 38-acre surface area. The reservoir is situated along the Middle Ditch Draw and serves as a crucial resource for flood risk reduction in the region.

Despite its low hazard potential, G. H. Reservoir has a poor condition assessment as of May 2021, indicating the need for maintenance and repair. The dam features an uncontrolled spillway with a width of 200 feet and one uncontrolled outlet gate. The surrounding drainage area is 17.4 square miles, with a maximum discharge capacity of 6,772 cubic feet per second. While the reservoir has not undergone significant modifications in recent years, regular inspections are conducted to ensure its structural integrity and safety.

In the event of an emergency, it is essential for the owners of G. H. Reservoir to have an updated Emergency Action Plan (EAP) in place to mitigate risks and protect downstream communities. With a moderate risk assessment rating, there is a need for proactive risk management measures to address any potential issues that may arise in the future. As a vital water resource in the region, G. H. Reservoir plays a crucial role in water storage and flood control, highlighting the importance of ongoing maintenance and oversight to ensure its continued functionality.
