Summary
With a primary purpose of serving as a Fish and Wildlife Pond, this earth dam stands at a height of 22 feet and stretches 480 feet in length. Its maximum storage capacity is 96 acre-feet, with a normal storage level of 37 acre-feet, covering a surface area of 8 acres.
The dam is regulated and inspected by the Illinois Department of Natural Resources, with a low hazard potential and a moderate risk assessment rating. The spillway, which is uncontrolled, has a width of 36 feet and a maximum discharge capacity of 325 cubic feet per second. Despite its age, the condition assessment of Armstrong Pond Dam 2 is currently listed as "Not Available," suggesting that further evaluation may be needed to ensure its continued safety and functionality for the surrounding environment and community.
Overall, Armstrong Pond Dam 2 serves as an important water resource for the area, providing habitat for fish and wildlife while also offering recreational opportunities. As climate change continues to impact water resources, it is essential for stakeholders to prioritize the maintenance and monitoring of dams like Armstrong Pond Dam 2 to adapt to changing conditions and ensure the safety and sustainability of these vital structures.

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.
