Summary
This Earth dam, with a height of 31 feet and a length of 680 feet, primarily serves the purpose of flood risk reduction for the surrounding area. With a storage capacity of 154.79 acre-feet and a normal storage of 17.75 acre-feet, the dam covers a surface area of 3.76 acres and drains a 0.42 square mile watershed.
Managed by the Kansas Department of Agriculture, this dam has been rated with a low hazard potential and a moderate risk assessment score of 3. Although its condition assessment is currently listed as "Not Rated," the dam is regularly inspected, permitted, and enforced by state regulatory agencies. While it does not have any associated structures or outlet gates, the dam's uncontrolled spillway of 40 feet width allows for a maximum discharge of 1472.48 cubic feet per second.
Overall, Dd No 12-12 plays a crucial role in mitigating flood risks in the region and ensuring the safety of nearby communities. With its strategic location and design characteristics, this dam stands as a vital component in the state's water resource management and climate resilience efforts.

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.
