Summary
Constructed in 1953, this earth dam stands at a height of 14 feet and has a storage capacity of 67 acre-feet. Despite being categorized as having a low hazard potential, Sd Noname 57 is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular state inspections, enforcement, and permitting.
Managed by a private owner, Sd Noname 57 serves multiple purposes, although specific details on its primary purpose and design remain unspecified. The dam has a maximum discharge capacity of 1470 cubic feet per second, with a normal storage level of 24 acre-feet. While the dam's condition assessment is currently listed as "Not Rated," it meets state jurisdiction requirements and is subject to state regulatory oversight to ensure its structural integrity and safety.
Situated within the St. Paul District of the US Army Corps of Engineers, Sd Noname 57 is not owned or funded by any federal agency. With no associated structures and a lack of detailed information on emergency action plans and risk management measures, this dam presents an intriguing case study for water resource and climate enthusiasts interested in private dam ownership and state regulation dynamics in South Dakota.

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.
