Summary
Built in 1997, this earthen dam stands at a height of 13.5 feet and has a storage capacity of 268.4 acre-feet. With a low hazard potential and a satisfactory condition assessment, the dam serves as a crucial component in managing water resources and mitigating flood risks in the region.
Designed by Jobes Henderson & Associates Inc., the Sandy Ridge Wetland Dam plays a significant role in maintaining the ecological balance of the area. With a normal storage capacity of 111.4 acre-feet and a surface area of 93.6 acres, the dam contributes to the overall health of the surrounding wetlands and supports a diverse range of flora and fauna. The dam's inspection frequency of 5 years ensures that it is regularly monitored for any maintenance or safety concerns.
Managed by the Ohio Department of Natural Resources, the Sandy Ridge Wetland Dam exemplifies responsible water resource management and climate adaptation practices. With its strategic location and efficient design, this dam stands as a testament to the importance of sustainable infrastructure in safeguarding communities against the impacts of changing weather patterns and increasing water variability.

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.
