Completed in 1964, this earth dam stands at a height of 96 feet and spans 6,500 feet, holding a maximum storage capacity of 346,655 acre-feet. The dam poses a high hazard potential due to its location on the Grand Neosho River and the potential for erosion of the embankment or foundation, which could lead to downstream flooding impacting nearby towns such as Council Grove, Emporia, and Hartford.
To manage the risks associated with Council Grove Dam, the US Army Corps of Engineers implements various measures, including conducting emergency exercises, updating the Emergency Action Plan annually, and maintaining the dam through regular inspections and maintenance activities. The dam also has a robust instrumentation and monitoring system in place to track changing conditions and ensure the structure's integrity. Despite the potential for flooding from the dam, downstream communities are reassured by the presence of the John Redmond Reservoir, which could contain the water released during a dam breach event, minimizing impacts further downstream. Overall, Council Grove Dam serves as a critical infrastructure for water resource management and climate resilience in the region.
