Macoupin Energy Recirculation Pond Dam dam
Macoupin Energy Recirculation Pond Dam
The Macoupin Energy Recirculation Pond Dam, located in Hardin, Illinois, serves as a crucial water supply source in the region. Constructed in 1970, this earth dam stands at a height of 43 feet and spans 325 feet in length. With a storage capacity of 248 acre-feet, it primarily supports water supply purposes for the surrounding area. Despite being categorized as having a high hazard potential, the dam is regularly inspected by the Illinois Department of Natural Resources to ensure its safety and compliance with state regulations.
Situated along the tributary of Spanish Needle Creek, this dam's spillway type is uncontrolled with a width of 50 feet. It has a risk assessment rating of moderate (3), indicating a need for ongoing monitoring and management measures. While the condition assessment of the dam is currently not available, the last inspection in September 2020 deemed it to be in operational condition. With its purpose of water supply and regulation by the Mine Safety and Health Administration, the Macoupin Energy Recirculation Pond Dam plays a vital role in safeguarding water resources in Macoupin County.
As part of the St. Louis District, this privately-owned dam is subject to state jurisdiction and regulation to ensure its structural integrity and safety. Despite not having a detailed risk management plan in place, the dam's emergency action plan is periodically reviewed and updated. With its significant contribution to water supply and the surrounding ecosystem, the Macoupin Energy Recirculation Pond Dam stands as a testament to the importance of responsible water resource management in the face of climate change challenges.

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 Macoupin Energy Recirculation Pond Dam
Where does the data for Macoupin Energy Recirculation Pond 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 High 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.
