The Upper Rio Hondo Site No. 1 Dam, also known as the Salado Creek Floodwater Retarding Structure, is a vital flood risk reduction infrastructure located in Lincoln, New Mexico. Built in 1959 by the USDA NRCS, this earth dam stands at a height of 94 feet and spans a length of 690 feet, effectively controlling the flow of Salado Creek and Gyp Spring Canyon. With a storage capacity of 7120 acre-feet and a maximum discharge rate of 13200 cubic feet per second, this dam plays a crucial role in protecting the surrounding area from potential flooding events.

Despite its significant contribution to flood risk reduction, the Upper Rio Hondo Site No. 1 Dam faces challenges in terms of its condition assessment, with a current rating of poor and a high hazard potential. The dam is regulated and inspected by the Office of the State Engineer in New Mexico, ensuring that necessary enforcement and permitting measures are in place to maintain its integrity. With a moderate risk assessment rating and a regular inspection frequency of 3 years, efforts are being made to manage and mitigate any potential risks associated with this critical infrastructure.

As a key component of the flood control system in the region, the Upper Rio Hondo Site No. 1 Dam serves as a crucial safeguard against water-related disasters. With its strategic location and design, this dam continues to play a vital role in protecting the community of Lincoln and its surroundings from the impacts of flooding, highlighting the importance of sustainable water resource management and climate resilience in the face of changing environmental conditions.
