Summary
This earth dam, standing at a height of 26 feet and with a length of 400 feet, has a maximum storage capacity of 35 acre-feet and covers a surface area of 3.6 acres. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition and lacks a formal emergency action plan.
With a spillway width of 12 feet and a maximum discharge capacity of 130 cubic feet per second, Bevill Dam serves as an essential component for flood control and water resource management in Marion County. While it is not regulated by the state or inspected regularly, the dam plays a crucial role in maintaining the stability of the surrounding area and preventing erosion. The dam's location within the Rock Island District underscores its significance in protecting local ecosystems and communities from potential water-related risks.
For water resource and climate enthusiasts, Bevill Dam represents a key infrastructure project that demonstrates the intersection of human intervention and natural processes. As a vital structure for grade stabilization along the TR-North River, the dam serves as a testament to the ongoing efforts to balance environmental conservation with human development in Missouri. While the dam's risk assessment remains moderate and its condition not formally rated, its role in managing water flow and mitigating potential hazards underscores the importance of monitoring and maintaining such structures to ensure long-term resilience in the face of changing climate conditions.

Dam Data Reference
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.
