Rist Canyon is a privately owned irrigation dam located in Larimer County, Colorado. Completed in 1882, this Earth-type dam stands at 12 feet tall and spans 800 feet in length, with a storage capacity of 63 acre-feet. Situated on the Rist Canyon stream, the dam serves the primary purpose of irrigation for the surrounding area, with a normal storage capacity of 57 acre-feet and a maximum discharge of 6 cubic feet per second.

Despite its low hazard potential, Rist Canyon dam has been assessed as unsatisfactory in condition, with the last inspection conducted in October 2013. The risk assessment for the dam is categorized as moderate, highlighting the importance of regular inspections and maintenance to ensure the safety and functionality of the structure. With state regulation, permitting, inspection, and enforcement in place, the dam is subject to oversight by the Colorado Division of Water Resources (DWR), ensuring compliance with safety standards and regulations.

For water resource and climate enthusiasts, Rist Canyon presents an intriguing case study of an older irrigation dam with historical significance in Colorado. With its Earth-type construction, moderate risk assessment, and unsatisfactory condition, the dam serves as a reminder of the ongoing maintenance challenges faced by aging infrastructure in the region. As efforts are made to address the structural concerns and ensure the safety of the dam, the story of Rist Canyon continues to unfold, reflecting the intersection of water management, engineering, and environmental stewardship in the face of evolving climate conditions.
