Marion is a privately owned dam located in Custer, Colorado, near the city of SAN ISABEL. Completed in 1909, this rockfill dam serves the primary purpose of water supply, with a normal storage capacity of 50 acre-feet. The dam stands at a height of 10 feet and has a length of 310 feet, impounding water from the AMETHYST CRK. stream.

Despite its low hazard potential, Marion poses a high risk due to its condition being labeled as 'Not Rated.' The dam lacks an Emergency Action Plan (EAP) and has not been assessed for its emergency preparedness or guideline compliance. With a drainage area of 3 square miles and a maximum discharge capacity of 150 cubic feet per second, it is crucial for stakeholders to prioritize the assessment and maintenance of Marion to ensure the safety and stability of its surrounding community and water resources.

As a water resource and climate enthusiast, monitoring Marion's risk assessment, condition assessment, and emergency preparedness measures is essential. With the potential for high risk associated with this dam, stakeholders must work towards implementing proper risk management measures and ensuring that emergency protocols are in place to mitigate any potential hazards that may arise from Marion's aging infrastructure.
