Summary
Built in 1958, this earth-type dam stands at a height of 23 feet and has a storage capacity of 119 acre-feet. Despite being regulated by the South Dakota Department of Environment and Natural Resources (DENR), the dam is considered low hazard with a "Not Rated" condition assessment.
The dam, with a length of 80 feet, plays a crucial role in water resource management in the area, providing irrigation and flood control benefits. While the dam has not been rated for its condition, it is subject to regular state inspections, permitting, and enforcement measures to ensure its safe operation. The dam's maximum discharge capacity is reported to be 2080 cubic feet per second, indicating its ability to handle significant water flow during peak periods.
Although Sd Noname 250 does not have a designated emergency action plan (EAP) or updated contact information, its low hazard potential and state-regulated status suggest a relatively stable infrastructure. As a point of interest for water resource and climate enthusiasts, this dam exemplifies the intersection of human-made structures and natural hydrological systems, highlighting the importance of proper management and maintenance for sustainable water resource utilization in South Dakota.

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.
