Summary
This earth dam, completed in 1972, stands at a height of 21 feet and has a length of 430 feet, providing a storage capacity of 84 acre-feet. Situated on the TRIB GRINDSTONE CREEK, this dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, enforcement, and permitting processes to ensure its safety and compliance with state regulations.
Despite its low hazard potential, Sd Noname 19 has not been rated for its condition assessment, and there is no information available on its emergency action plan or risk management measures. The dam's location in a rural area with no associated structures and a lack of detailed data on its infrastructure and maintenance schedule raises questions about its long-term resilience and preparedness for potential climate-related challenges. With a maximum discharge capacity of 1190 cubic feet per second, the dam plays a crucial role in managing water resources in the region, highlighting the importance of continuous monitoring and maintenance to mitigate risks and protect surrounding communities and ecosystems.
Overall, Sd Noname 19 serves as a vital infrastructure for water resource management in South Dakota, yet there are gaps in information regarding its condition assessment, emergency preparedness, and risk management strategies. As climate change continues to pose challenges to water infrastructure resilience, ensuring the safety and effectiveness of dams like Sd Noname 19 is essential for safeguarding communities and ecosystems in the face of increasing hydrological risks. Collaboration between private owners, state regulators, and federal agencies will be crucial in addressing these gaps and enhancing the sustainability of critical water infrastructure in the region.

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.
