Designed by Shive Hattery, this Earth-type dam stands at a height of 15 feet with a length of 1250 feet, providing a storage capacity of 75 acre-feet. The dam's spillway, which is uncontrolled, spans 96 feet in width to manage a maximum discharge of 200 cubic feet per second.
With a hazard potential rated as significant and a risk assessment of moderate, the dam plays a pivotal role in safeguarding the surrounding areas from potential flooding events. The Iowa Department of Natural Resources regulates and inspects the dam, ensuring its structural integrity and compliance with safety standards. Despite not having a current condition assessment, the John Deere Tcao Dam remains a critical infrastructure contributing to water resource management and climate resilience efforts in the region.
