Summary
Constructed in 1950, this Earth dam stands at a height of 18 feet and has a length of 1000 feet, providing a storage capacity of 273 acre-feet. With a low hazard potential and a condition assessment that is currently not rated, Sd Noname 196 serves as an important structure for regulating the flow of the Cheyenne River.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 196 is subject to state regulation, permitting, inspection, and enforcement. While the dam has not been rated for its condition, it is considered to have a low hazard potential, indicating its overall stability and safety. The dam's primary purpose and associated structures are not specified, but its location along the Cheyenne River underscores its importance in water management and flood control efforts.
With a maximum discharge capacity of 1800 cubic feet per second, Sd Noname 196 plays a crucial role in mitigating flood risks and ensuring water availability in the region. Despite its age, the dam continues to serve its purpose effectively, showcasing the importance of proper maintenance and oversight in safeguarding water resources and addressing climate-related challenges.

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.
