Summary
Built in 1976, this earth-type dam has a height of 30 feet and a storage capacity of 257 acre-feet. With a low hazard potential and a condition assessment that is currently not rated, the dam ensures the safety of the surrounding area while providing essential water resources for agricultural needs.
Although privately owned, Carrol Lake Dam is not regulated or inspected by the state of Missouri. It is situated in an area with a drainage area of 110 square miles and a surface area of 16 acres, making it a crucial component of the local water management system. Despite not having an Emergency Action Plan (EAP) in place, the dam's low hazard potential indicates a relatively low risk to the community, but there is still room for improvement in terms of risk assessment and management measures.
Overall, Carrol Lake Dam stands as a significant irrigation structure in Missouri, ensuring water availability for agricultural purposes in the region. With its moderate storage capacity and low hazard potential, the dam plays a crucial role in water resource management, despite lacking state regulation and inspection. Moving forward, implementing an EAP and conducting regular risk assessments could further enhance the safety and efficiency of this key water infrastructure.

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.
