Summary
With a height of 19 feet and a length of 161 feet, the dam has a storage capacity of 120 acre-feet and a spillway width of 44 feet. The dam is state-regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its safety and integrity.
Despite being classified as having a low hazard potential, the Panhandle Eastern Waverly Lake Dam is considered to have a moderate risk level. The dam is equipped with uncontrolled spillways and outlet gates, and has not been modified in recent years. Although the condition assessment is not available, the dam is inspected every 5 years to monitor its structural integrity and ensure its continued safe operation. While the dam is not owned or funded by any federal agency, it remains an important recreational resource for the local community.
For water resource and climate enthusiasts, the Panhandle Eastern Waverly Lake Dam provides an interesting case study in private dam ownership and state regulation. With its picturesque location on Trib Apple Creek and its role in providing recreational opportunities, this dam serves as a vital component of the local landscape. As efforts to address climate change and water resource management continue to evolve, understanding the infrastructure and regulatory considerations of dams like the Panhandle Eastern Waverly Lake Dam is crucial for ensuring the safety and sustainability of our water resources.

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.
