Summary
Built in 1950, this earth dam stands at a height of 22 feet and stretches 400 feet in length, with a storage capacity of 130 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources, which oversees permitting, inspection, and enforcement of safety measures.
With a significant hazard potential, Sd Noname 191 has not been rated for its condition assessment. Despite this, the dam has not been modified in recent years and lacks emergency action plans. The Natural Resources Conservation Service is responsible for the design of this dam and ensures its compliance with federal regulations. The dam's maximum discharge capacity is 1800 cubic feet per second, highlighting the importance of monitoring its structural integrity and emergency preparedness.
As water resource and climate enthusiasts, it is crucial to recognize the vital role dams like Sd Noname 191 play in managing water resources. By understanding the regulatory framework, potential hazards, and the need for emergency preparedness, we can work towards ensuring the safety and sustainability of our water infrastructure in the face of changing climatic conditions.

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.
