Summary
Constructed in 1960 by the Natural Resources Conservation Service, this Earth-type dam stands at a height of 15 feet and has a length of 200 feet. With a storage capacity of 78 acre-feet, the dam serves the primary purpose of water resource management in the area.
Despite its age, Sd Noname 228 has a low hazard potential and is currently rated as 'Not Rated' in terms of its condition assessment. The dam has not undergone recent inspections or assessments, and its emergency action plan status is unknown. The risk management measures and guidelines for the dam are also not specified, indicating a need for further evaluation and maintenance to ensure its safety and functionality in the face of potential climate challenges.
As a water resource and climate enthusiast, the data on Sd Noname 228 presents an intriguing case of a privately-owned dam in South Dakota with a critical role in managing water resources along the TR-BAD RIVER. With its historical significance and vital function in the region, there is a clear need for continued monitoring and maintenance to uphold its integrity and mitigate any potential risks associated with its age and condition. This serves as a reminder of the importance of sustainable water management practices in the face of changing climate patterns and environmental pressures.

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.
