Summary
Built in 1987 by the USDA NRCS, this earth-type dam stands at a height of 21 feet and has a length of 1272 feet, providing a storage capacity of 430 acre-feet to protect the surrounding areas from potential flooding events. With a low hazard potential and a moderate risk assessment, this dam plays a crucial role in mitigating flood risks in the region.
Managed by the Kansas Department of Agriculture, Dd No 122 is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and functionality. Even though the dam is not federally owned, funded, or operated, it serves as a vital component of the local flood control infrastructure, showcasing the collaborative efforts between state and local agencies in safeguarding communities and natural resources against the impacts of extreme weather events. With a spillway width of 40 feet and a maximum discharge capacity of 1166 cubic feet per second, this dam is equipped to handle high water levels during heavy rainfall.
As water resource and climate enthusiasts monitor the state of dams like Dd No 122, it is important to recognize the role of such structures in enhancing resilience to changing weather patterns and increasing flood risks. With its strategic location in the Deer Creek watershed and its effective flood risk reduction capabilities, this dam stands as a testament to the importance of proactive infrastructure planning and management in safeguarding communities and ecosystems from the impacts of climate change.

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.
