Summary
This dam serves the primary purpose of regulating the flow of the tributary Silver Creek, providing a maximum storage capacity of 414 acre-feet and a normal storage capacity of 205 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," this dam plays a crucial role in water resource management within the region.
Managed by the local government and regulated by the South Dakota Department of Environment and Natural Resources, Silver Creek Watershed Dt Dam S-6 undergoes state permitting, inspection, and enforcement to ensure its structural integrity and operational efficiency. The dam's location in the SESE,10-103-49 coordinates and its affiliation with the St. Paul District of the USACE reflect its importance in the broader water infrastructure network. With a design by the Natural Resources Conservation Service and ownership by the local government, this dam exemplifies collaborative efforts in safeguarding water resources for the community.
As an essential component of the water management system in Minnehaha County, Silver Creek Watershed Dt Dam S-6 contributes to flood control, water supply, and environmental protection in the region. While its current risk assessment and emergency preparedness details are not specified, the dam's historical significance and continued functionality underscore the importance of proactive monitoring and maintenance practices. For water resource and climate enthusiasts, understanding the role of this earth dam in sustaining the ecological balance and hydrological stability of the Silver Creek watershed is crucial for promoting sustainable water management practices in the area.

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.
