Summary
Built in 1966, this earth-type dam on the TR-Cheyenne River boasts a height of 28 feet and a storage capacity of 40 acre-feet. While its primary purpose remains unspecified, its role in regulating water flow, providing irrigation, and controlling flood risk is evident. Managed by the Natural Resources Conservation Service, this dam is subject to state regulations and inspections, ensuring its continued safe operation.
Despite its low hazard potential, Sd Noname 29 has not been rated for its condition assessment. The dam's last inspection date, emergency action plan, and risk assessment details are unavailable, suggesting a need for comprehensive monitoring and maintenance protocols. With a maximum discharge capacity of 1575 cubic feet per second, this dam plays a critical role in water management within the St. Paul District. As climate change impacts water resources, understanding the structural integrity and operational efficiency of dams like Sd Noname 29 becomes increasingly vital for sustainable water governance.
As South Dakota's water infrastructure faces evolving challenges, the maintenance and regulation of dams like Sd Noname 29 are integral to ensuring water security and resilience in the region. With a strategic location on the TR-Cheyenne River and a history of service since the 1960s, this dam represents a key asset in water resource management. Moving forward, prioritizing regular inspections, condition assessments, and emergency preparedness measures will be crucial in upholding the safety and functionality of Sd Noname 29 amidst changing climate dynamics.

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.
