Summary
Built in 1991, this earth dam stands at a height of 23.5 feet and stretches 2508 feet in length, providing storage for up to 1198.6 acre-feet of water. The dam's primary purpose is flood risk reduction, with a low hazard potential and a moderate risk assessment rating.
Managed by the Kansas Department of Agriculture, this dam is state regulated, permitted, inspected, and enforced to ensure its proper functioning and safety. Situated on Turkey Creek, this structure plays a crucial role in managing water flow and reducing flood risks in the area. Despite its importance, the dam is currently not rated for its condition and lacks an emergency action plan, highlighting areas where improvement and attention may be needed in the future.
With a spillway width of 75 feet and the capacity to discharge up to 1400 cubic feet per second, Dd No A-3 is a key component in the flood risk reduction strategy for Neosho, Kansas. As climate change continues to impact water resources, structures like Dd No A-3 will be crucial in managing and mitigating the effects of extreme weather events in the region. The collaboration between local government and state agencies ensures the proper management and maintenance of this essential water resource infrastructure.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
