Summary
Built in 1951, this earth dam stands at a height of 20 feet and has a length of 400 feet. It has a NID storage capacity of 208 acre-feet, with a maximum discharge rate of 300 cubic feet per second. Despite its low hazard potential, the dam's condition is currently not rated.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 176 is subject to state regulation, permitting, inspection, and enforcement. The dam is within the jurisdiction of the state and is regularly monitored for safety and compliance. While no associated structures or emergency action plans have been reported for this dam, it remains a significant feature in the local water resource and climate landscape.
Located in a rural area with no nearby city, Sd Noname 176 serves as a vital infrastructure for water management and flood control along the Cheyenne River. With its historical significance dating back to the mid-20th century, this dam contributes to the overall water resources management in South Dakota. Enthusiasts of water resources and climate will find Sd Noname 176 an intriguing example of how private ownership and state oversight intersect in the realm of dam infrastructure.

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.
