Summary
Completed in 1956, this earth dam stands at a height of 34 feet and spans 362 feet in length. With a storage capacity of 74 acre-feet, it provides a serene setting for water enthusiasts to enjoy activities on Underwood Pond. The dam's low hazard potential and moderate risk assessment make it a key feature in the area's water resource management.
Managed by the Illinois Department of Natural Resources, Underwood Pond Dam is equipped with an uncontrolled spillway and outlet gates. Its condition assessment is currently not available, but regular inspections are conducted every 5 years to ensure structural integrity and safety. While the dam's emergency action plan status is unclear, its compliance with state permitting, inspection, and enforcement regulations demonstrates a commitment to responsible water resource management in the region.
Climate and water resource enthusiasts will find Underwood Pond Dam to be a captivating structure in the Peoria County landscape. Its association with the Jubilee Creek tributary and its contribution to local water storage and recreational opportunities highlight the intersection of human infrastructure and natural ecosystems. With its unique design and historical significance, Underwood Pond Dam serves as a focal point for understanding the importance of sustainable water resource management in the face of changing climate patterns.

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.
