Summary
Built in 1950, this earth dam spans 600 feet and has a storage capacity of 114 acre-feet, with a normal storage level of 83 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), and is subject to state jurisdiction, permitting, inspection, and enforcement.
The dam is situated on the TR-CHEYENNE river or stream and falls under the St. Paul District of the US Army Corps of Engineers. Managed by the Natural Resources Conservation Service, Sd Noname 115 has not been rated for its condition assessment and does not have an Emergency Action Plan prepared. With a maximum discharge of 420 cubic feet per second, the dam serves as a vital infrastructure for water resource management in the area and contributes to flood control efforts in the region.
Despite its unassessed condition, Sd Noname 115 continues to play a crucial role in the local water management system, offering storage and flood protection benefits to the surrounding community. As climate change impacts become more pronounced, the importance of maintaining and monitoring dams like Sd Noname 115 will only increase, highlighting the need for comprehensive risk assessment and management measures to ensure the safety and reliability of these essential structures for water resource enthusiasts and climate advocates alike.

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.
