Summary
1-B in Perry, Ohio, is a crucial earth dam built in 1975 by the USDA NRCS with a primary purpose of flood risk reduction along the tributary to Little Rush Creek. Standing at a height of 44.5 feet and a length of 460 feet, this structure has a storage capacity of 1144 acre-feet and serves as a vital resource for managing water flow and protecting the surrounding area from potential flooding events. The dam is regulated and inspected by the Department of Natural Resources in Ohio, ensuring its operational effectiveness and structural integrity.
Despite its satisfactory condition assessment as of June 2017, Rush Creek Structure No. 1-B is classified with a high hazard potential due to its location and the potential consequences of failure. The dam has a moderate risk rating and undergoes regular inspections every five years to ensure its ongoing safety and functionality. While the dam has uncontrolled spillways and outlet gates, it plays a crucial role in flood risk management within the region, highlighting the importance of maintaining and monitoring such water resource structures for the well-being of the community and the environment.

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.
