Summary

Vi-A, located in Fairfield, Ohio, is a vital flood risk reduction structure on Little Rush Creek. Built in 1982 by the USDA NRCS, this earth dam stands at a height of 57.6 feet and spans 1550 feet in length. With a storage capacity of 15,386 acre-feet and a drainage area of 28.24 square miles, this structure plays a crucial role in managing water resources in the area.

Owned by the local government and regulated by the Department of Natural Resources, Rushcreek Structure No. Vi-A has a high hazard potential and a fair condition assessment. Despite its age, the dam has undergone regular inspections every 5 years, with the last assessment conducted in April 2017. Additionally, the dam has an uncontrolled spillway and outlet gates, indicating its importance in flood risk mitigation for the surrounding community.

With a moderate risk assessment rating, Rushcreek Structure No. Vi-A serves as a key component in the region's water resource management system. As climate change continues to impact water levels and precipitation patterns, structures like this play a crucial role in safeguarding communities from potential flooding events. By remaining vigilant in inspections and maintenance, stakeholders can ensure that Rushcreek Structure No. Vi-A continues to fulfill its vital role in protecting the area from flood risks.

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. 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

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, 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.
