Avalon is a historic Earth dam located on the Pecos River in Carlsbad, New Mexico, completed in 1906 for the primary purpose of irrigation. Managed by the Bureau of Reclamation, this federal structure stands 58 feet tall and spans 1025 feet in length, with a maximum storage capacity of 20,000 acre-feet and a normal storage level of 4,334 acre-feet. The dam's hazard potential is classified as high, with a moderate risk assessment rating.

Despite its age, Avalon underwent structural modifications in 2002 to ensure its continued safety and functionality. The dam features an uncontrolled spillway with a width of 970 feet, capable of discharging up to 145,000 cubic feet per second. While the condition assessment of the dam is currently listed as not available, regular inspections are conducted, with the last one taking place in August 2020. Additionally, an Emergency Action Plan (EAP) has been prepared, albeit with some details pending updates and revisions.

Water resource and climate enthusiasts will find Avalon to be a significant piece of infrastructure in the region, contributing to irrigation, water supply, and flood control efforts along the Pecos River. Its historical value, engineering design, and ongoing management by the Bureau of Reclamation offer a compelling case study for understanding the intersection of water management, infrastructure resilience, and environmental stewardship. As a vital component of the water infrastructure in Eddy County, New Mexico, Avalon serves as a reminder of the importance of sustainable water resource management in arid regions.
