Summary
This dam is situated on the TR-BAD RIVER and is under the regulatory authority of the South Dakota Department of Environment and Natural Resources. With a storage capacity of 108 acre-feet, Sd Noname 72 serves as a low hazard structure with a condition assessment that is currently not rated.
Managed by the Natural Resources Conservation Service, Sd Noname 72 has not been modified in recent years and does not have an Emergency Action Plan (EAP) prepared. Despite its low hazard potential, the dam is subject to regular state inspections, permitting, and enforcement to ensure its structural integrity and compliance with safety regulations. Dusty Johnson, the Congressional representative for the area, oversees federal regulations related to the dam through the St. Paul District of the US Army Corps of Engineers.
For water resource and climate enthusiasts, Sd Noname 72 offers a glimpse into the intricate network of dams and water infrastructure in South Dakota. Understanding the history, purpose, and management of structures like Sd Noname 72 is crucial for ensuring the sustainable use of water resources and mitigating potential risks associated with dams. As climate change continues to impact water availability and quality, the maintenance and regulation of these essential structures play a vital role in safeguarding communities and ecosystems 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.
