Eagle Rock is a privately owned dam located in Weld County, Colorado, along the Simpson Creek-TR river. Built in 1968, this Earth dam stands at a height of 27 feet and spans 680 feet in length. The primary purpose of Eagle Rock is for recreation, with secondary purposes including irrigation. The dam has a storage capacity of 83 acre-feet and covers a surface area of 9 acres.

Despite its low hazard potential, Eagle Rock poses a high risk due to its condition assessment being "Not Rated." It is regulated by the Colorado Division of Water Resources (DWR) and undergoes regular inspections every 6 years. The dam does not have a spillway and is not equipped with outlet gates. While it currently does not have an Emergency Action Plan (EAP) in place, it meets regulatory guidelines for state permitting, inspection, and enforcement.

Water resource and climate enthusiasts will find Eagle Rock to be an intriguing structure to study, given its location in a region susceptible to climate variability and water resource management challenges. The dam's historical significance, combined with its recreational and irrigation purposes, make it a valuable piece of infrastructure to monitor and assess in the context of changing environmental conditions and water usage demands in the area.
