Marcot Park, also known as Green Back Grave, is a privately owned irrigation dam located in Cedaredge, Delta County, Colorado. Completed in 1956, this earth dam stands at a height of 39 feet and has a storage capacity of 648 acre-feet, serving the primary purpose of irrigation. With a surface area of 43 acres and a drainage area of 3 square miles, the dam on the Surface Creek-TR river system plays a vital role in water resource management in the region.

Despite its fair condition assessment and high hazard potential, Marcot Park dam is regulated, inspected, and enforced by the Colorado Department of Water Resources, ensuring its safe operation and maintenance. The dam lacks a spillway and features slide and uncontrolled outlet gates, making it essential for ongoing risk assessment and management measures to prevent potential emergencies. The surrounding area is at risk of inundation, emphasizing the importance of emergency preparedness and adherence to guidelines for the dam's operation.

With a high risk rating and a history of periodic inspections, Marcot Park dam remains a critical infrastructure for irrigation in the region. As climate change continues to impact water resources, enthusiasts and stakeholders must closely monitor and support the maintenance and management of dams like Marcot Park to ensure the sustainable utilization of water for agricultural purposes and environmental conservation in Colorado.
