Summary
Vi-D, also known as Oakthorpe Reservoir, is a vital component in flood risk reduction efforts along the Indian Creek. Built in 1975 by the USDA NRCS, this earth dam stands at a height of 51.5 feet and has a storage capacity of 2150 acre-feet. With a normal storage capacity of 377 acre-feet and a surface area of 41.8 acres, this structure plays a crucial role in managing water flow in the region.
Managed by the local government and regulated by the Department of Natural Resources, Rushcreek Structure No. Vi-D is subject to regular inspections to ensure its safety and efficiency. The dam has been assessed as satisfactory, with a moderate risk level. Despite its high hazard potential, the structure has proven to be effective in mitigating flood risks for the surrounding areas. With its uncontrolled spillway and satisfactory condition, Rushcreek Structure No. Vi-D remains a key asset in water resource management and climate resilience efforts in Ohio.
As a part of the flood risk reduction infrastructure, Rushcreek Structure No. Vi-D plays a critical role in protecting the community of Oakthorpe and its surrounding areas from potential flooding events. With its solid design and efficient operation, this earth dam continues to contribute to the overall water management efforts in the region, ensuring the safety and well-being of local residents. Supported by the USDA NRCS and monitored by the local government, Rushcreek Structure No. Vi-D stands as a testament to effective collaboration in water resource management and climate adaptation strategies.

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.
