Summary
This privately owned earth dam stands at a height of 31 feet and has a storage capacity of 498 acre-feet, with a normal storage level of 310 acre-feet. The dam is situated on a tributary to East Honey Creek and is under the jurisdiction of the Rock Island District of the US Army Corps of Engineers.
Despite being classified as having a low hazard potential, Hedgewood Dam has not been rated for its condition assessment. This dam does not fall under state regulations for inspection, permitting, or enforcement. Although there is no designated emergency action plan in place, the dam is monitored by its private owner to ensure the safety of the surrounding community and the integrity of the structure. As a valuable asset for water resource management in the area, Hedgewood Dam provides essential services for both agricultural and environmental needs.
Enthusiasts of water resources and climate will find Hedgewood Dam to be a fascinating case study in private dam ownership and management. With its unique design as an earth dam with buttress core type, this structure plays a crucial role in sustaining the local ecosystem and economy. As stakeholders continue to monitor and maintain the dam, it stands as a testament to the importance of responsible stewardship of water resources in the face of changing climate conditions.

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.
