Summary
Managed by the South Dakota Department of Environment and Natural Resources (DENR), this earth dam stands at a height of 25 feet and has a length of 400 feet. Completed in 1952, the dam has a storage capacity of 70 acre-feet and a maximum discharge of 1225 cubic feet per second.
Despite its low hazard potential, Sd Noname 287 is not currently rated for its condition assessment. The dam has not been inspected recently, and emergency preparedness measures such as an Emergency Action Plan (EAP) are not in place. With Dusty Johnson as the representative for the area, it is essential for stakeholders to assess and address any potential risks associated with the dam to ensure the safety of the surrounding community and the sustainability of the water resources in the region.
As water resource and climate enthusiasts, it is crucial to monitor and advocate for the proper maintenance and assessment of dams like Sd Noname 287 to prevent potential disasters and ensure the efficient management of water resources. Collaboration between state agencies, owners, and regulators is essential to address any issues related to dam safety and emergency preparedness, ultimately safeguarding communities and the environment from potential risks.

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.
