Summary
This earth dam stands at a height of 19 feet and was completed in 1954. It serves the primary purpose of water storage, with a capacity of 372 acre-feet and a normal storage level of 180 acre-feet. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 68 is regulated, permitted, inspected, and enforced by the state. Although it is not associated with any federal agencies, it is under the jurisdiction of the St. Paul District of the US Army Corps of Engineers. The dam has a maximum discharge capacity of 1260 cubic feet per second and features no spillways, locks, or outlet gates.
Despite the lack of recent inspection dates and assessment updates, Sd Noname 68 has not been deemed a high-risk structure. The dam does not have an Emergency Action Plan (EAP) in place or inundation maps prepared, but it meets state guidelines for emergency preparedness. With its historical significance and moderate storage capacity, Sd Noname 68 remains a notable water resource structure in South Dakota for climate and water enthusiasts to observe and study.

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.
