Summary
Built in 2008 and standing at a height of 21 feet, the dam has a storage capacity of 83 acre-feet, with a normal storage level of 32 acre-feet. Despite its relatively low hazard potential, the dam is regulated, inspected, and enforced by the South Dakota Department of Environment and Natural Resources (DENR).
The dam features an uncontrolled spillway with a width of 80 feet, and has a moderate risk rating of 3. While the condition assessment of the dam is currently not rated, it meets inspection and enforcement requirements, suggesting a commitment to safety and compliance with regulatory guidelines. Although the dam does not have outlet gates and has not been modified in recent years, it plays a crucial role in managing water resources in the area and mitigating potential flood risks.
Located in Marshall County, Anderson Dam is a vital piece of infrastructure in the region, serving as a key component in water resource management and flood control efforts. As climate change continues to impact water availability and extreme weather events, the importance of well-maintained and regulated dams like Anderson Dam cannot be understated. With a focus on safety, compliance, and risk management, Anderson Dam exemplifies the importance of proactive measures in safeguarding water resources and communities against potential hazards.

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.
