Summary
Constructed in 1959 by the Natural Resources Conservation Service, this earth dam stands at a height of 25 feet and stretches 507 feet in length. With a storage capacity of 81 acre-feet, the dam serves the primary purpose of water resource management in the area.
Despite being regulated and inspected by the South Dakota Department of Environment and Natural Resources, Noldner Number 1 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam has a maximum discharge of 1071 cubic feet per second and a normal storage level of 63 acre-feet. While the emergency action plan status and risk assessment details remain unknown, the dam continues to play a crucial role in mitigating flood risks and providing water storage for the region.
Located within the St. Paul District, Noldner Number 1 offers a glimpse into the intricate network of dams and reservoirs that contribute to water resource management and climate resilience. As climate change continues to impact water availability and extreme weather events, the importance of maintaining and monitoring dams like Noldner Number 1 becomes increasingly evident in ensuring the safety and sustainability 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.
