Summary
Built in 1935, this earth dam stands at a height of 17 feet and has a storage capacity of 70 acre-feet. With a maximum discharge of 800 cubic feet per second, Sd Noname 169 serves primarily for flood control and water storage purposes in the region.
Managed by the South Dakota Department of Environment and Natural Resources, Sd Noname 169 is regulated, permitted, inspected, and enforced for compliance with state guidelines. Despite being classified as a low hazard potential dam, its condition assessment is marked as "Not Rated," indicating a need for further evaluation. Emergency action plans and risk assessments are currently not available, highlighting potential areas for improvement in ensuring the safety and integrity of the structure.
As water resource and climate enthusiasts, the data on Sd Noname 169 provides valuable insights into the management and condition of this critical infrastructure. With its location in a rural area and limited associated structures, the dam plays a crucial role in mitigating flood risks and supporting water supply management in the region. Continued monitoring, assessment, and emergency preparedness are essential to ensure the long-term safety and functionality of Sd Noname 169 in the face of changing environmental conditions.

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.
