Summary
The dam stands at a height of 15 feet and has a storage capacity of 100 acre-feet. It is situated on a tributary of Frozen Man Creek, with a drainage area of 7 square miles.
Despite being classified as a low hazard potential structure, Neuharth Dam #2 is subject to state regulation, inspection, and enforcement by the South Dakota Department of Environment and Natural Resources. The dam features an uncontrolled spillway with a width of 100 feet and has a maximum discharge capacity of 1350 cubic feet per second. In terms of risk assessment, the dam is rated as moderate (3), highlighting the importance of ongoing monitoring and management measures to ensure its structural integrity and functionality.
As a significant component of the local water resource infrastructure, Neuharth Dam #2 plays a crucial role in water storage and management in the area. Its construction and operation are closely monitored by state authorities to mitigate potential risks and ensure public safety. For water resource and climate enthusiasts, this dam serves as a point of interest for understanding the intersection of infrastructure, environmental regulations, and risk management in the context of water resource development.

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.
