Summary
Built in 1955, this earthen dam stands at a height of 15 feet and has a storage capacity of 92 acre-feet. With a maximum discharge of 840 cubic feet per second, the dam serves a significant hazard potential and is regulated by the South Dakota Department of Environment and Natural Resources (DENR).
Despite its age, Sd Noname 49 has not been rated for its condition, and no recent inspections or assessments have been conducted. The dam's emergency action plan (EAP) status and risk management measures are also unknown, raising concerns about its readiness for potential hazards. The dam's location in a rural area with limited infrastructure highlights the importance of ensuring its safety and preparedness in the face of changing climate conditions.
As water resource and climate change enthusiasts, it is crucial to monitor and advocate for the proper maintenance and regulation of dams like Sd Noname 49. By staying informed about the condition and management of critical infrastructure, we can work towards safeguarding our water resources and communities from the impacts of extreme weather events and aging 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.
