Summary
Built in 1945, it stands at a height of 16 feet and has a storage capacity of 64 acre-feet, with a normal storage level of 38 acre-feet. The dam spans 905 feet in length and is designed to handle a maximum discharge of 2350 cubic feet per second. Despite its age, Anderson 5 has been assessed as having a low hazard potential and its condition remains unrated.
Managed by the South Dakota Department of Environment and Natural Resources, Anderson 5 is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. While the dam does not have a designated primary purpose or associated structures, its role in water resource management and flood control in the TR-BELLE FONot RatedCHE river or stream watershed is significant. The dam's location within the Omaha District and under the oversight of the DENR reflects its importance in supporting water resource and climate initiatives in the region.
With no documented emergency action plan or risk assessment in place, Anderson 5 presents an opportunity for further evaluation and potential enhancements to its safety protocols. As a key infrastructure asset in the region, the dam's maintenance and monitoring are crucial for safeguarding the surrounding community and environment from potential hazards. By staying informed and engaged with the management of Anderson 5, water resource and climate enthusiasts can contribute to the sustainable stewardship of this essential piece of infrastructure in South Dakota.

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.
