Non Potable Reservoir Dam 4, located in El Paso County, Colorado, was completed in 1958 by the renowned design firm SKIDMORE, OWINGS, AND MERRILL. This Federal-owned earth dam stands at 80 feet in height, with a maximum storage capacity of 150 acre-feet and a surface area of 6.5 acres. The dam primarily serves the purpose of flood risk reduction along Goat Camp Creek, a tributary in the area.

The dam's structure includes buttress core types resting on rock and soil foundations, with an uncontrolled spillway width of 20 feet. The dam's low hazard potential is supported by regular state inspections and maintenance, demonstrating a commitment to safety and regulatory compliance by the US Air Force, the primary owning and operating agency. Despite its moderate risk assessment, the dam's overall condition assessment remains unavailable, highlighting the importance of ongoing monitoring and risk management measures for its continued safety and functionality.

Non Potable Reservoir Dam 4 not only plays a crucial role in flood risk reduction but also supports irrigation purposes in the region. Located in Colorado Springs and under the jurisdiction of the Department of Defense USAF, this dam is a vital component of the local water resource infrastructure. As water resource and climate enthusiasts, understanding and appreciating the design, construction, and ongoing maintenance of dams like Non Potable Reservoir Dam 4 is essential for ensuring the resilience and sustainability of our water supply systems in the face of changing environmental conditions.
