Summary
Completed in 1998 for flood risk reduction purposes, this dam stands at a height of 22.5 feet and has a length of 842 feet. With a storage capacity of 205.81 acre-feet, it serves to control debris and reduce the risk of flooding in the area. The dam is situated on the South Big Creek-TR river and has a low hazard potential with a moderate risk assessment rating.
Despite its modest hazard potential, Dd No 109 plays a crucial role in managing flood risk in Coffey County, Kansas. The dam's construction was funded and overseen by local government authorities, with no federal agency involvement in its design, construction, or regulation. While the dam has not been inspected or assessed in recent years, it continues to provide valuable flood protection to the surrounding area, with a normal storage capacity of 17.77 acre-feet and a maximum discharge of 661 cubic feet per second.
As climate change continues to impact weather patterns and water resources, structures like Dd No 109 are essential for safeguarding communities against the threat of flooding. By effectively controlling debris and reducing flood risks, this earth dam plays a crucial role in protecting the residents of LeRoy and the wider Coffey County region. With a focus on flood risk reduction and a history of successful operation since its completion in 1998, Dd No 109 remains a vital component of the local water resource management system in Kansas.

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.
