Summary
This Earth-type dam was completed in 1950 and stands at a height of 18 feet with a length of 400 feet. The dam has a storage capacity of 86 acre-feet, with a normal storage level of 54 acre-feet. It is regulated by the South Dakota Department of Environment and Natural Resources, which oversees permitting, inspection, and enforcement activities to ensure its safety and compliance with state regulations.
Despite being classified as having a low hazard potential and a condition assessment of "Not Rated," Sd Noname 230 serves an important role in water resource management for the surrounding area. The dam has not been inspected recently, and its emergency action plan status, risk assessment, and inundation maps are currently unknown. The Natural Resources Conservation Service was responsible for its design, indicating a commitment to sustainable water resource management practices.
Located in the St. Paul District of South Dakota, Sd Noname 230 provides vital water storage for the region and plays a crucial role in flood control and irrigation. While its current condition and emergency preparedness status are unclear, the dam's historical significance and impact on the local water supply highlight the importance of ongoing monitoring and maintenance to ensure its continued safety and effectiveness in managing water resources and mitigating the effects of climate change.

Dam Data Reference
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.
