Summary
This dam stands at a height of 21.5 feet and has a NID storage capacity of 233.36 acre-feet, with a normal storage capacity of 29.88 acre-feet. Despite being classified as having a low hazard potential, the dam has a moderate risk assessment rating of 3, indicating some level of risk associated with its operation and maintenance.
The structure, designed by J. Dale Steward, has a spillway width of 50 feet and a maximum discharge capacity of 690 cubic feet per second. The dam's condition assessment is currently listed as "Not Rated," and it has not been inspected since November 2019. Despite the lack of recent inspection data, the dam is regulated, permitted, inspected, and enforced by the Kansas Department of Agriculture, ensuring that it meets state safety and regulatory standards. With its strategic location and purpose, Dd No 118 plays a crucial role in mitigating flood risks and protecting the surrounding area from potential water-related disasters.
Water resource and climate enthusiasts will find Dd No 118 an intriguing case study in dam infrastructure and management, showcasing the importance of effective design, regulation, and maintenance in ensuring the safety and functionality of water control structures. From its construction history to its current risk assessment status, this earth dam in Osage City serves as a vital component of flood risk reduction efforts in the region, demonstrating the intersection of engineering, environmental conservation, and public safety in managing water resources.

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.
