John Martin Dam, located in Lamar, Colorado, was completed in 1943 by the US Army Corps of Engineers with the primary purpose of flood risk reduction along the Arkansas River. The dam, a gravity type structure standing at 25 feet tall and stretching 13,000 feet long, provides crucial irrigation and flood protection benefits to the surrounding areas. However, a recent risk assessment identified the dam's breach risk as high, with potential life-threatening consequences for downstream communities in Colorado and Kansas.

To manage the risk associated with John Martin Dam, the US Army Corps of Engineers implements various measures including routine inspections, maintenance activities, and risk communication efforts. These measures aim to monitor the dam's performance, assess potential risks, and enhance emergency response capabilities in case of a breach. With ongoing evaluations and maintenance projects, the Corps is dedicated to ensuring the safety and functionality of the dam while keeping the surrounding communities informed and prepared for any potential emergencies.
