Summary
Built in 1960, this earth dam stands at 20 feet high and stretches 200 feet in length, offering a storage capacity of 200 acre-feet. Despite its modest size, Sd Noname 247 plays a crucial role in the region's water resource management, with a maximum discharge capacity of 3300 cubic feet per second.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 247 is subject to state regulations, inspections, and enforcement measures to ensure its safe operation. With a low hazard potential and a current "Not Rated" condition assessment, the dam serves as a reliable water control structure for the local community. While details on emergency action plans and risk management measures are not available at this time, the dam's presence contributes to the overall water infrastructure in the area, under the oversight of the St. Paul District of the US Army Corps of Engineers.
For water resource and climate enthusiasts, Sd Noname 247 represents a vital piece of South Dakota's water management puzzle. Its location on the TR-BAD RIVER, together with its regulated status and low hazard potential, highlights the significance of this earth dam in maintaining water security and flood control measures in the region. As efforts continue to monitor and assess the condition of Sd Noname 247, its role in sustaining the local ecosystem and supporting community water needs remains essential for a sustainable future.

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.
