Summary
With a height of 30 feet and a length of 610 feet, this dam provides a maximum storage capacity of 111.94 acre-feet and covers a surface area of 5.08 acres. The dam is regulated by the Kansas Department of Agriculture and is subject to state permitting, inspection, and enforcement.
Despite being categorized as having a low hazard potential, Dd No 13 is considered to have moderate risk, indicating a need for ongoing risk management measures. The dam features an uncontrolled spillway with a width of 60 feet and no outlet gates. While the condition of the dam is currently not rated, it is essential for dam safety authorities to conduct regular inspections to ensure its structural integrity and functionality in mitigating flood risks in the region.
In terms of emergency preparedness, there is no available information on the existence of an emergency action plan (EAP) or inundation maps for Dd No 13. However, with its critical role in flood risk reduction for the area, it is crucial for the dam owners and regulatory agencies to prioritize the development of comprehensive emergency response plans and risk management strategies to safeguard the community and surrounding environment from potential water-related disasters.

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.
