Summary
Built in 1970 by USDA NRCS, this earth dam stands at a height of 23 feet and spans 225 feet in length. With a storage capacity of 110 acre-feet, the dam serves as a barrier on TRIB SILVER CREEK, offering a serene environment for water resource and climate enthusiasts to enjoy.
Managed by the Illinois Department of Natural Resources, Heenren Pond Dam is regulated, permitted, inspected, and enforced to ensure its safety and functionality. Despite its low hazard potential, the dam is subject to moderate risk assessment and undergoes inspections every 5 years. While the condition assessment is not currently available, the structure continues to provide recreational opportunities to the community, with an uncontrolled spillway and outlet gates in place for water management.
As part of the St. Louis District under the supervision of the Natural Resources Conservation Service, Heenren Pond Dam remains a focal point for outdoor activities in Montgomery County, Illinois. Its presence not only enhances the local landscape but also contributes to the conservation and utilization of water resources for the benefit of both humans and wildlife in the area.

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.
