Summary
Built in 1956, this earth dam stands at a height of 17 feet and has a storage capacity of 68 acre-feet. It serves multiple purposes, although specific details are not provided in the data. Despite its age, the dam is in a low hazard potential category and has not been rated for its condition as of yet.
Managed by the Natural Resources Conservation Service, Sd Noname 264 is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement in place. As a crucial infrastructure for water resource management in the area, the dam plays a vital role in flood control, irrigation, or other potential uses. The presence of this dam underscores the importance of sustainable water resource management in the face of changing climate patterns.
With a maximum discharge capacity of 504 cubic feet per second, Sd Noname 264 is equipped to handle significant water flow during extreme weather events. While the dam has not been assessed for its emergency action plan or risk management measures, its presence highlights the importance of proactively addressing potential hazards to ensure the safety and resilience of water infrastructure in the region. For water resource and climate enthusiasts, Sd Noname 264 serves as a focal point for understanding the intersection of water management, climate resilience, and regulatory oversight in maintaining critical infrastructure.

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.
