Summary

Completed in 2007, this earth dam stands at a height of 24 feet with a hydraulic height of 22 feet and a structural height of 29 feet. It has a length of 360 feet and a storage capacity of 52.1 acre-feet, providing essential water resource management for the surrounding area.

With a low hazard potential and a moderate risk assessment rating, Circle V Dam plays a crucial role in mitigating the potential impacts of floods and ensuring water availability for the local community. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 59 cubic feet per second. Despite not being regulated by the state or subject to regular inspections, Circle V Dam remains a vital infrastructure for maintaining water quality and quantity in the region.

Overall, Circle V Dam is an important structure that contributes to the sustainable management of water resources in Missouri. With its efficient design and low-risk profile, this dam serves as a key asset for grade stabilization and water storage, highlighting the importance of private initiatives in supporting climate resilience and water security in the face of changing environmental conditions.

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.
