Bevill Dam dam
Bevill Dam
Bevill Dam, located in Hannibal, Missouri, is a privately owned structure constructed in 1967 for grade stabilization purposes along the TR-North River. 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.

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.
- 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.
- 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.
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, environmental 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.

About Bevill Dam
Where does the data for Bevill Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
