Big Island Wetland Dam dam
Big Island Wetland Dam
The Big Island Wetland Dam in Green Camp, Marion, Ohio, is a state-regulated earth dam completed in 1995 primarily for recreation purposes. 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
- 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.
- 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.
- 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.
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, environmental 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.

About Big Island Wetland Dam
Where does the data for Big Island Wetland Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
