Deer Lake in Larimer County, Colorado, is a private water resource managed by the state regulatory agency, Department of Water Resources. Built in 1919, this Earth dam stands at a height of 10 feet and has a storage capacity of 92 acre-feet, primarily used for recreation purposes such as fishing and wildlife observation. With a surface area of 11 acres and located in the Columbine Canyon along the COLUMBINE CANYON river or stream, Deer Lake offers a serene escape just 27 miles from FORT COLLINS.

Despite its low hazard potential and satisfactory condition assessment, Deer Lake poses a high risk factor due to its proximity to the congressional District 02, Colorado. The dam lacks a spillway but has a spillway width of 200 feet, ensuring the safety of the surrounding area in case of overflow. The last inspection in 2013 showed no significant issues, with an inspection frequency of every 6 years. Emergency protocols, including an Emergency Action Plan (EAP), are currently under review to meet safety guidelines and risk management measures.

Water and climate enthusiasts visiting Deer Lake will appreciate its historical significance and recreational offerings, providing a vital water supply while maintaining a focus on wildlife preservation and environmental stewardship. As a picturesque destination for outdoor activities and nature appreciation, Deer Lake stands as a testament to responsible water resource management and the importance of maintaining a balance between human enjoyment and ecological sustainability in the face of changing climate patterns.
