Bunker Lake, also known as Bunker Basin or Haley Reservoir, is a private irrigation reservoir located in Rio Blanco, Colorado. Built in 1913, this earth dam stands at a height of 9 feet and has a storage capacity of 307 acre-feet. With a primary purpose of irrigation, Bunker Lake serves as a vital water resource for the surrounding agricultural community.

Although Bunker Lake is classified as having a low hazard potential, it is considered to have a high risk level due to its condition assessment being "Not Rated". The last inspection of the dam took place in July 1990, with an inspection frequency of 6 years. Despite its risk level, the reservoir does not have an Emergency Action Plan (EAP) in place, which could pose challenges in the event of an emergency situation.

Water resource and climate enthusiasts interested in Bunker Lake will find it intriguing for its historical significance, its role in irrigation, and its potential risk level. As a privately owned reservoir, it plays a crucial role in supporting the agricultural activities in the region while also highlighting the importance of proper dam maintenance and emergency preparedness in water resource management.
