Summary
With a height of 20 feet and a length of 400 feet, this dam serves multiple purposes including flood control and water storage. Despite its low hazard potential, the dam has not been rated for its current condition.
Under the regulation of the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 276 undergoes regular inspections, permitting, and enforcement to ensure its structural integrity and compliance with state standards. With a maximum storage capacity of 144 acre-feet and a normal storage of 48 acre-feet, this dam plays a vital role in managing water resources in the region. Additionally, its association with the St. Paul District of the US Army Corps of Engineers further emphasizes its importance in water management.
Although lacking detailed risk assessment and emergency response protocols, Sd Noname 276 remains a key infrastructure in the area's water resource management. As climate change continues to impact water availability and extreme weather events, the maintenance and upkeep of such dams become crucial in safeguarding communities and ecosystems from potential risks and disasters.

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.
