Summary
Structure in Virden, Illinois, is a privately owned dam regulated by the Illinois Department of Natural Resources. The primary purpose of this earth dam is for water supply, with a height of 11 feet and a storage capacity of 130 acre-feet. Despite being classified as low hazard potential, the last inspection conducted in August 2017 revealed that the condition assessment is not available.
Located in Macoupin County, this impoundment structure plays a crucial role in the local water supply system. Managed by Mine Safety and Health Administration, it meets the necessary state regulations for permitting, inspection, and enforcement. Although the dam has not been modified in recent years, it serves as a vital resource for the community and is maintained to ensure its safety and functionality.
With no emergency action plan in place and limited risk assessment information available, it is essential for the owners and regulators to prioritize the maintenance and monitoring of the Clarified Pond Impound. Structure to prevent any potential hazards and ensure the continued supply of water to the area. Despite its low-risk classification, regular inspections and adherence to safety guidelines are crucial for the long-term sustainability and effectiveness of this important water resource 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.
