Summary
Completed in 1937, this earth dam serves multiple purposes, including water storage and flood control. With a maximum storage capacity of 820 acre-feet and a normal storage of 486 acre-feet, Freeman Dam plays a crucial role in managing water resources in the region.
Owned and regulated by the state of South Dakota, Freeman Dam has a low hazard potential and a 23-foot dam height. Despite not being rated for condition assessment, the dam undergoes regular inspections every three years to ensure its structural integrity and functionality. The dam's emergency action plan status and risk management measures are currently unspecified, highlighting the need for continued monitoring and preparation for potential emergencies.
In addition to its practical functions, Freeman Dam also offers a glimpse into the region's history and engineering achievements. With its close proximity to Jackson County and contribution to the local ecosystem, Freeman Dam remains a significant landmark for water resource and climate enthusiasts interested in understanding the intersection of infrastructure, conservation, and community resilience.

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.
