Summary

Completed in 1986, this earth dam stands at a height of 29.5 feet and serves the primary purpose of flood risk reduction along the Gregg Creek-TR river/stream. With a normal storage capacity of 36.8 acre-feet and a drainage area of 0.35 square miles, the dam plays a crucial role in debris control and flood risk mitigation in the region.

Despite its low hazard potential, Gs Dd No 28-14 (Kirk) has a moderate risk assessment rating of 3, indicating the need for ongoing monitoring and risk management measures. The dam features an uncontrolled spillway with a width of 56 feet and no outlet gates. Although the condition assessment is currently not rated, the dam has not been subject to recent inspections. The surrounding area has a surface area of 4.6 acres and a maximum discharge capacity of 1436 cubic feet per second.

For water resource and climate enthusiasts, Gs Dd No 28-14 (Kirk) presents an intriguing case study in flood risk reduction and dam infrastructure in the Kansas City District. With its unique design features and moderate risk assessment, this earth dam serves as a vital asset in managing water resources and protecting the surrounding communities from potential flooding events. As efforts continue to monitor and assess the condition of the dam, its role in maintaining the safety and resilience of the region remains paramount.

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.
