The Wall, located in Campbell, Wyoming, is a privately owned earth dam constructed in 2009 for irrigation purposes along the Wall Draw river. Designed by Hugh Lowham, the dam stands at a height of 38 feet with a hydraulic height of 33 feet, and a length of 455 feet. It has a storage capacity of 32 acre-feet and covers a surface area of 1.9 acres, serving as a critical water resource for the surrounding area.

With a low hazard potential and fair condition assessment, The Wall is regularly inspected every 5 years to ensure its safety and functionality. It features an uncontrolled spillway with a width of 30 feet and an outlet gate with a valve. The dam plays a crucial role in providing water for irrigation, fire protection, and stock maintenance, highlighting its importance in sustaining the local ecosystem and economy in Wyoming.

Despite its moderate risk assessment, The Wall demonstrates a commitment to risk management measures and compliance with state regulations. As a key infrastructure for water management in the region, it serves as a reminder of the intricate balance between water resources, climate factors, and human intervention in maintaining a sustainable environment.
