Summary
It stands at a height of 9 feet, with a length of 2600 feet, and has a storage capacity of 616.4 acre-feet, providing a surface area of 115.5 acres for recreational activities. The dam is located on a tributary of the Scioto River and is under the jurisdiction of the Department of Natural Resources in Ohio.
Despite its significant hazard potential, the Big Island Wetland Dam is currently assessed as being in poor condition, with the last inspection conducted in November 2020. The dam's emergency action plan status, risk assessment, and management measures are not specified in the available data. Its inspection frequency is set at 5 years, with the dam having been designed by Jobes Henderson & Associated, Inc. The dam's condition assessment and risk management aspects would be crucial factors for water resource and climate enthusiasts to monitor and advocate for improvements to ensure the safety and sustainability of this important wetland ecosystem.
In addition to offering recreational opportunities, the Big Island Wetland Dam plays a vital role in water resource management and conservation in the region. With its location on a tributary of the Scioto River, the dam helps regulate water flow, store water for various uses, and support the local ecosystem. As enthusiasts interested in water resources and climate, it is essential to stay informed about the dam's condition, inspection reports, and any potential risks or management measures to ensure the long-term resilience and sustainability of this valuable wetland infrastructure.

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.
