Summary
Standing at a height of 12 feet and with a length of 1230 feet, this earth dam has a storage capacity of 85 acre-feet and a maximum discharge of 3400 cubic feet per second. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is inspected, permitted, and enforced by state agencies.
Despite its low hazard potential, the condition of John Anderson 2 is currently not rated, and emergency action plans and risk assessments are not available for the dam. It is situated on the TR-BELLE FOURCHE river/stream and falls under the jurisdiction of the Omaha District of the US Army Corps of Engineers. With a primary purpose not specified, this dam serves as a crucial component of the local water resource infrastructure, providing flood control and water storage for the surrounding area.
For water resource and climate enthusiasts, John Anderson 2 presents an intriguing case study of a historic dam in South Dakota. As efforts to enhance dam safety and resilience continue to evolve, monitoring and evaluating the condition and regulatory oversight of structures like John Anderson 2 are essential for ensuring the sustainable management of water resources 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.
