Summary
Constructed in 1968 by the USDA NRCS, this earth dam stands at a height of 30 feet and spans 305 feet in length. With a primary purpose of supporting fish and wildlife habitats, the dam also serves other functions such as fire protection and stock or small fish pond management.
Managed by a private owner, the Walter Pence Pond Dam is regulated by the Illinois Department of Natural Resources, with state inspections and enforcement in place to ensure its safety and compliance. With a maximum storage capacity of 51 acre-feet and a normal storage level of 36 acre-feet, the dam plays a crucial role in maintaining the ecological balance of the surrounding area. The dam's spillway, which is uncontrolled and 20 feet wide, helps manage water flow and prevent overflow during periods of high discharge.
Despite being classified as having a moderate risk level, the Walter Pence Pond Dam remains an essential structure for the community, providing valuable resources for both wildlife and residents alike. As climate change continues to impact water resources, the maintenance and management of dams like Walter Pence Pond are crucial in ensuring the sustainability and resilience of our ecosystems.

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.
