Summary

Completed in 1948, this earth-type dam has a storage capacity of 120 acre-feet and serves the primary purpose of water resource management on the TR-Rapid Creek. The dam is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement measures in place.

Managed by a private owner, Sd Noname 16 plays a crucial role in maintaining water levels and discharge rates in the region, with a maximum discharge capacity of 360 cubic feet per second. The dam has not been rated for its condition assessment, and emergency action preparedness status is currently unknown. Despite these uncertainties, the dam's location and design contribute to the overall water resource management efforts in the area, under the oversight of the state regulatory agency.

With its historical significance dating back to the mid-20th century, Sd Noname 16 stands as a testament to the careful balance between infrastructure development and environmental stewardship. As climate change continues to impact water resources, the role of dams like Sd Noname 16 in ensuring water security and mitigating risks becomes increasingly important. As enthusiasts of water resources and climate, understanding the nuances of such infrastructure projects is essential for promoting sustainable practices and resilience in the face of a changing climate.

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.
