Summary
This earth dam stands at a height of 32 feet and has a storage capacity of 51 acre-feet, with a normal storage level of 26 acre-feet. Despite its low hazard potential, the dam has not been rated for its condition assessment.
Owned privately, Fordyce Lake Dam also serves various other purposes such as debris control, fire protection, and recreational activities. With its buttress core type and unlisted foundations, the dam covers a surface area of 3 acres and drains a 90-acre watershed. Managed by the Rock Island District of the US Army Corps of Engineers, the dam has not undergone recent inspections or emergency action plan updates, highlighting potential gaps in maintenance and risk management protocols.
For water resource and climate enthusiasts, Fordyce Lake Dam represents a crucial piece of infrastructure in the region, balancing the dual roles of flood protection and recreational amenity. As a privately owned structure, its condition and maintenance practices may require closer monitoring to ensure continued safety and efficiency in fulfilling its multiple purposes. The dam's location in a low-hazard area underscores the importance of proactive risk management and emergency preparedness, calling for regular inspections and updates to its operation guidelines.

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.
