Summary
This earth dam stands at a height of 18.5 feet with a structural height of 23.5 feet, serving the primary purpose of flood risk reduction in the area. The dam has a normal storage capacity of 56.92 acre-feet and a drainage area of 0.65 square miles, providing protection to the surrounding community from potential flooding events.
Managed by the Kansas Department of Agriculture, Dd No 128 is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. While the dam has a low hazard potential, it has been rated as not yet assessed for its current condition. With a moderate risk assessment rating, measures for risk management are yet to be determined. Despite not having associated structures or outlet gates, the dam plays a crucial role in mitigating flood risks along Deer Creek-TR.
Dd No 128's strategic location in Lone Elm, Kansas, within the Kansas City District, highlights its importance in the local water resource and climate management efforts. With its completion in 2010, the dam has since provided essential flood protection to the community and continues to be monitored for any potential risks or hazards. For water resource and climate enthusiasts, Dd No 128 serves as a key example of proactive flood risk reduction infrastructure in the region.

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.
