Summary
With a height of 25.2 feet and a length of 1400 feet, this structure provides a maximum storage capacity of 895.4 acre-feet and covers a surface area of 278 acres. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level, with various risk management measures in place.
Managed by the Kansas Department of Agriculture and regulated by state authorities, Dd No 129 is inspected and permitted regularly to ensure its structural integrity and compliance with safety standards. While the dam's condition assessment is currently not rated, it meets the necessary guidelines for emergency action preparedness. The presence of an uncontrolled spillway with a width of 40 feet allows for the controlled release of water during periods of high discharge, minimizing the risk of overtopping and potential downstream flooding.
Overall, Dd No 129 plays a crucial role in mitigating flood risks in the region and protecting nearby communities from water-related disasters. Its strategic location and design, coupled with regular inspections and risk management measures, underscore the importance of proper water resource management in safeguarding against the impacts of climate change and extreme weather events.

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.
