Comanche, located in Larimer, Colorado, is a local government-owned dam with a primary purpose of irrigation. Completed in 1966, this earth dam stands at a height of 46 feet and has a maximum storage capacity of 3,240 acre-feet. Serving the Beaver Creek, Comanche plays a vital role in water supply and management in the region, with a normal storage capacity of 2,629 acre-feet and a drainage area of 11 square miles.

With a high hazard potential and a satisfactory condition assessment as of July 2020, Comanche is regulated and inspected by the Colorado Department of Water Resources. The dam features an uncontrolled spillway with a width of 150 feet and a maximum discharge capacity of 15,179 cubic feet per second. Despite its moderate risk assessment rating, Comanche has not had a detailed risk management plan or inundation maps prepared as of the latest data update in March 2021. In the event of an emergency, the dam's emergency action plan status and adherence to guidelines remain unspecified. For water resource and climate enthusiasts, Comanche presents an intriguing case study in dam infrastructure and risk management within the Colorado landscape.
