Columbine, also known as Reynolds, is a privately owned dam located in Hotchkiss, Colorado. This earth dam was completed in 1950 for the primary purpose of irrigation and water supply. Standing at a height of 26 feet with a length of 400 feet, Columbine has a storage capacity of 214 acre-feet and serves the surrounding area with a normal storage of 175 acre-feet.

Managed by the Colorado Division of Water Resources, Columbine is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. The dam has a low hazard potential and is classified as being in satisfactory condition as of the last assessment in 2016. Despite its age, Columbine meets guidelines for emergency action plans, but risk assessments indicate a high risk level, prompting the need for continued monitoring and risk management measures.

Located on Leroux Creek, Columbine plays a crucial role in irrigation and water supply for the region. With its historical significance and importance for local agriculture, water resource and climate enthusiasts can appreciate the engineering behind this structure and the efforts to maintain its integrity for the community's benefit.
