Monument, located in Gunnison, Colorado, is a privately owned irrigation dam on Minnesota Creek-TR that has been in operation since 1889. With a height of 51 feet and a storage capacity of 632 acre-feet, this earth dam serves the primary purpose of irrigation for the surrounding area. The dam has a structural height of 76 feet and a spillway width of 13 feet, with a maximum discharge of 518 cubic feet per second.

Despite being privately owned, Monument is regulated and inspected by the Colorado Department of Water Resources, ensuring its safety and compliance with state regulations. The dam has a high hazard potential due to its location and storage capacity, but it is currently rated in fair condition following the latest inspection in June 2020. While the dam does not have a formal Emergency Action Plan in place, it meets state permitting and inspection requirements, providing reassurance for the local community in the event of an emergency. For water resource and climate enthusiasts, Monument represents a historic and vital piece of infrastructure that continues to play a crucial role in supporting agricultural activities in the region.
