Lajoya, located in Huerfano, Colorado, is a private water resource infrastructure designed for irrigation purposes. Built in 1901, this earth dam stands at a height of 18 feet and spans a length of 1560 feet. The reservoir has a storage capacity of 273 acre-feet and serves multiple purposes including fire protection, stock watering, and small fish pond maintenance in addition to irrigation.

Although classified as having a low hazard potential, the dam's condition was assessed as unsatisfactory during the last inspection in December 2012. The risk assessment for Lajoya is moderate, indicating the need for ongoing monitoring and potential risk management measures to ensure the safety and integrity of the structure. With a drainage area of 2 square miles and a maximum discharge capacity of 16 cubic feet per second, the reservoir plays a crucial role in supporting agricultural activities and wildlife habitat in the region.

Despite its age, Lajoya continues to play a vital role in water management in the area. With state regulation and inspection in place, efforts are being made to address the dam's condition and ensure its continued functionality. As a key component of the local water infrastructure, Lajoya serves as a reminder of the importance of maintaining and monitoring water resources in the face of changing climate conditions.
