Summary

Built in 1954 by the USDA NRCS, this buttress dam stands at a height of 41 feet with a hydraulic height of 35 feet. The dam's primary purpose is flood risk reduction, providing a storage capacity of 149 acre-feet and a spillway width of 50 feet.

Managed by the Kansas Department of Agriculture, this structure is state-regulated, inspected, and enforced to ensure its safety and functionality. With a significant hazard potential, the dam's condition is currently not rated, and its last inspection was conducted in July 2019. The area surrounding the dam is closely monitored, and emergency preparedness measures are in place, although specific details such as an Emergency Action Plan (EAP) and risk assessment are not readily available. Overall, Dd No Sc-4 serves as a crucial asset in mitigating flood risks in the Marshall County region of Kansas, showcasing the importance of water resource management in climate-vulnerable areas.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
