Summary
Iv-A, also known as Pearsons, is a vital flood risk reduction infrastructure located in Bremen, Ohio. Designed by the USDA NRCS and completed in 1979, this earth dam stands at a height of 26 feet and spans a length of 590 feet. With a NID storage capacity of 1664.5 acre-feet, it serves the primary purpose of flood risk reduction for the tributary to Rushcreek, protecting the surrounding area from potential inundation.
Managed by the Department of Natural Resources in Ohio, Rushcreek Structure No. Iv-A is subject to regular state regulation, inspection, and enforcement to ensure its operational integrity. Its spillway type is uncontrolled, with a significant hazard potential and a satisfactory condition assessment as of the last inspection in September 2017. While it has not been modified in recent years, its risk assessment categorizes it as having a moderate risk level, highlighting the importance of continued monitoring and maintenance to safeguard the community from potential flood events.
As an essential component of the local government's flood risk reduction strategy, Rushcreek Structure No. Iv-A plays a crucial role in protecting the Perry County area in Ohio from the impacts of high water events. With its significant storage capacity and strategic location, this dam stands as a testament to the collaborative efforts between federal, state, and local agencies to mitigate the potential risks posed by climate variability and ensure the safety and resilience of the community in the face of changing environmental 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.
