Summary

Completed in 2003, this earth dam stands at a height of 27 feet with a structural height of 29 feet, serving a primary purpose of grade stabilization. With a storage capacity of 22 acre-feet, this dam plays a crucial role in managing water resources in the area.

Despite being privately owned, Jackie Hague Jr Dam falls under the jurisdiction of the state of Missouri, with no state regulatory agency overseeing its operations. The dam's low hazard potential and moderate risk assessment rating highlight the importance of its role in mitigating potential flooding events in the region. The spillway type for this dam is uncontrolled with a width of 10 feet, allowing for controlled release of excess water during times of high flow.

With a drainage area of 120 acres and a normal storage capacity of 16 acre-feet, Jackie Hague Jr Dam contributes to the overall water management efforts in Mercer County, Missouri. Its strategic location and design by the Natural Resources Conservation Service make it a vital infrastructure for climate enthusiasts and water resource professionals interested in sustainable water management practices in the region.

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.
