Summary
Standing at a height of 18 feet and stretching 300 feet in length, this dam has a storage capacity of 84 acre-feet, with a normal storage level of 25 acre-feet. Despite its low hazard potential and a condition assessment of 'Not Rated', the dam is regulated, inspected, and enforced by the South Dakota Department of Environment and Natural Resources.
Managed by the Natural Resources Conservation Service, Sd Noname 269 plays a critical role in water resource management within the region. With a maximum discharge capacity of 1200 cubic feet per second, this dam serves as an important infrastructure for flood control and water supply in the area. Although lacking detailed risk assessment and emergency action plans, the dam continues to function effectively under the oversight of state regulatory agencies.
Water resource and climate enthusiasts can appreciate the significance of Sd Noname 269 in maintaining water stability and mitigating potential risks in the region. As a key piece of infrastructure in South Dakota, this earth dam exemplifies the importance of proper regulation, inspection, and maintenance to ensure the safety and reliability of water resource systems 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.
