Summary
Completed in 1986, this earth dam stands at a height of 24 feet and spans a length of 560 feet along the tributary of Little Minnesota River. With a storage capacity of 100 acre-feet and a maximum discharge rate of 1250 cubic feet per second, the dam plays a vital role in flood control and water supply for the surrounding area.
Despite its low hazard potential, Anderson East Dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources. While its condition assessment is currently marked as "Not Rated," the dam's emergency action plan readiness and risk management measures are not specified in the available data. As a significant infrastructure within the region, the dam's operational efficiency and structural integrity are essential for ensuring the safety and sustainability of water resources in Marshall County.
With its strategic location and function, Anderson East Dam represents a critical component of the local water management infrastructure. As water resource and climate enthusiasts, understanding the design, purpose, and regulatory oversight of this dam provides valuable insights into the intersection of human development and environmental stewardship in the face of changing climatic conditions. As such, ongoing monitoring and maintenance efforts are essential to safeguarding the dam's effectiveness in mitigating flood risks and supporting sustainable water utilization in the region.

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.
