Summary

Constructed in 1955 by the Natural Resources Conservation Service, this dam stands at a height of 12 feet and has a length of 890 feet. With a maximum storage capacity of 202 acre-feet and a normal storage of 100 acre-feet, Sd Noname 34 serves as a water resource management structure in the region.

Despite being categorized as having a low hazard potential and being in "Not Rated" condition, Sd Noname 34 is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources. The dam does not have an Emergency Action Plan (EAP) or inundation maps prepared, highlighting areas for potential improvement in emergency preparedness and risk assessment. Overall, Sd Noname 34 plays a crucial role in water storage and management in the region, contributing to the resilience of the local water resource system.

Water resource and climate enthusiasts will find Sd Noname 34 an intriguing case study of a privately-owned dam in South Dakota, showcasing the intersection of water management, regulatory oversight, and emergency preparedness. With its historical significance dating back to 1955 and its pivotal role in managing water flow along the TR-BAD RIVER, this dam serves as a reminder of the importance of infrastructure maintenance and risk assessment in the face of changing climate patterns. As discussions around water resource management and climate adaptation continue to evolve, Sd Noname 34 offers valuable insights into the complexities of balancing water needs with environmental stewardship.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
