Summary
Built in 1996, this earth dam stands at a height of 33.3 feet with a hydraulic height of 27 feet and a structural height of 32 feet. The dam stretches 400 feet in length and has a storage capacity of 52 acre-feet, with a normal storage level of 34 acre-feet. The dam's low hazard potential and moderate risk assessment make it a key structure for managing water resources in the area.
Despite being privately owned, Reynolds Dam falls under the jurisdiction of the state of Missouri and is not regulated or permitted by any state agency. The dam's uncontrolled spillway with a width of 10 feet helps manage maximum discharges of up to 37 cubic feet per second. With a surface area of 3 acres and a drainage area of 108.8 square miles, Reynolds Dam plays a crucial role in maintaining water levels and mitigating flood risks in the region. Although the dam's condition assessment is not rated, its risk management measures and emergency preparedness contribute to its overall effectiveness in water resource management.

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.
