Summary
Designed by the USDA NRCS, this earth dam stands at 29 feet high and spans 360 feet in length. Its primary purpose is to serve as a Fish and Wildlife Pond, while also providing opportunities for recreation.
With a storage capacity of 35 acre-feet and a drainage area of 0.04 square miles, Hadden Pond Dam features an uncontrolled spillway with a width of 26 feet. Despite its low hazard potential, the dam poses a moderate risk according to the data, calling for ongoing risk management measures. The condition assessment is currently not available, and the last inspection was conducted in April 2019.
Overall, Hadden Pond Dam serves as a vital resource for fish and wildlife in the area, offering a serene recreational spot for visitors. Its design and construction by the Natural Resources Conservation Service reflect a commitment to environmental conservation and management. As climate and water resource enthusiasts, the data on Hadden Pond Dam provides valuable insights into the infrastructure and management of this important water feature in Morgan County, Illinois.

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.
