About this dam

Bolivar Dam - Magnolia Levee

Bolivar Dam - Magnolia Levee, located in Carroll County, Ohio, is a Federal-owned structure managed by the US Army Corps of Engineers. Completed in 1951, this Earth-type dam stands at a height of 31 feet and spans a length of 4877 feet along Sandy Creek. The primary purpose of the dam is flood risk reduction, with a high hazard potential and an Emergency Action Plan in place to address potential risks.

The US Army Corps of Engineers regularly monitors the condition of Bolivar Dam - Magnolia Levee and implements risk management measures to mitigate flood risks associated with the structure. This includes collaborating with local emergency managers to develop and update emergency action plans, as well as conducting regular maintenance and repairs to ensure the dam's structural integrity. The dam has limited capacity to store water, and releases may be necessary to manage water levels, especially during severe weather events that could overwhelm the system.

Overall, Bolivar Dam - Magnolia Levee serves as a critical infrastructure for flood risk reduction in the area, with the US Army Corps of Engineers taking proactive steps to manage and address potential risks associated with the dam. As efforts continue to safeguard the surrounding communities, further details specific to this dam will be added in the future to enhance understanding and preparedness for any potential dam-related emergencies.

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.

FAQ

About Bolivar Dam - Magnolia Levee

Where does the data for Bolivar Dam - Magnolia Levee 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 High 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.
