Summary

This earth dam, standing at a height of 14 feet and completed in 1938, serves the primary purpose of water storage with a capacity of 101 acre-feet. The dam, regulated by the South Dakota Department of Environment and Natural Resources (DENR), has a significant hazard potential and has not been rated for its current condition.

Managed by private owners, Sd Noname 14 is subject to state jurisdiction, regulation, permitting, inspection, and enforcement. Despite its age, the dam has a normal storage capacity of 56 acre-feet and a maximum discharge rate of 420 cubic feet per second. While the dam's condition has not been officially assessed, its location in a high-risk area underscores the importance of regular inspections and maintenance to ensure public safety and water resource management.

With a history dating back to the late 1930s, Sd Noname 14 remains a vital structure for water storage along Rapid Creek. As water resource and climate enthusiasts, understanding the significance of this dam in the local ecosystem and community is crucial for promoting responsible water management practices and emergency preparedness. Stay tuned for updates on the dam's condition and safety measures as its role in water resource management continues to evolve.

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.
