Summary
Constructed as an earth dam with a height of 31 feet and a length of 1000 feet, it serves a primary purpose of mitigating flood hazards in the area. The dam has a storage capacity of 419.63 acre-feet, with a normal storage level of 62.01 acre-feet.
Managed by the Kansas Department of Agriculture, Dd No 12 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam features an uncontrolled spillway with a width of 100 feet, allowing for a maximum discharge of 5520 cubic feet per second during flood events. While the last inspection dates back to July 1996, the dam's risk assessment is moderate, indicating a need for ongoing monitoring and management measures to ensure its effectiveness in flood risk reduction.
With a history dating back to the late 20th century, Dd No 12 stands as a critical infrastructure for flood control in the region. Despite its low hazard potential, the dam's moderate risk assessment highlights the importance of regular inspections and maintenance to uphold its capacity to protect the surrounding areas from potential flooding. As water resource and climate enthusiasts, staying informed about the condition and management of dams like Dd No 12 is crucial for ensuring the safety and resilience of communities in the face of changing climate patterns and increasing water-related risks.

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.
