Rock is a private irrigation dam located in Cowdrey, Colorado, on Newcomb Creek. Completed in 1961, this earth-type structure stands 14 feet tall and spans 600 feet in length, with a storage capacity of 76 acre-feet. Despite its low hazard potential, Rock is regulated by the Colorado Division of Water Resources, with regular inspections and enforcement measures in place to ensure its safety and functionality.

With a normal storage capacity of 56 acre-feet and a maximum discharge of 588 cubic feet per second, Rock plays a crucial role in supporting agricultural activities in the region. Although it has not undergone a recent condition assessment, the dam is considered to have a high risk due to its age and lack of updated emergency preparedness measures. While it currently does not have a spillway, Rock's location and structural integrity are closely monitored to prevent any potential risks to downstream communities.

As a vital piece of infrastructure in the area, Rock serves as a reminder of the importance of water resource management and climate resilience. Its history, design, and regulatory oversight highlight the intricate balance between meeting irrigation needs and ensuring public safety. Water resource and climate enthusiasts can appreciate the ongoing efforts to maintain and monitor Rock to protect both the environment and local communities from potential hazards.
