Summary
Iv-E, also known as Flagdale Lake, is a vital flood risk reduction structure located in Bremen, Ohio. Constructed in 1979 by the USDA NRCS, this earth dam stands at a height of 29 feet and has a length of 680 feet, providing storage capacity of 1035 acre-feet and a normal storage level of 138.1 feet. With a significant hazard potential and satisfactory condition assessment, this structure plays a crucial role in protecting the surrounding area from flooding.
Operated and regulated by the Department of Natural Resources in Ohio, Rushcreek Structure No. Iv-E serves the primary purpose of flood risk reduction for the tributary to Rush Creek. With a moderate risk assessment rating of 3, this structure demonstrates the importance of proper maintenance and inspection to ensure its continued effectiveness in managing water resources in the region. The dam's uncontrolled spillway and outlet gates are designed to handle a maximum discharge of 5209 cubic feet per second, safeguarding the community in the event of heavy rainfall or rising water levels.
As a key component of water resource management in Perry County, Ohio, Rushcreek Structure No. Iv-E embodies the collaboration between local government and regulatory agencies to mitigate flood risks and protect the environment. With a history of successful operation and a commitment to regular inspections, this structure stands as a testament to the importance of sustainable water infrastructure for climate resilience and community safety.

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.
