Summary
Designed by USDA NRCS and completed in 1962, this earth dam stands at a height of 22 feet and has a storage capacity of 215 acre-feet. Situated on the Silver Creek river, the dam plays a crucial role in regulating water flow and managing flood risks in the area.
Managed by the South Dakota Department of Environment and Natural Resources, Silver Creek Watershed Dt #4 is state-regulated and undergoes regular inspections, enforcement, and permitting to ensure its safety and functionality. With a low hazard potential and a condition assessment of "Not Rated," the dam serves as a key infrastructure for water resource management in the region. Despite being non-rated, the dam's design and construction by the Natural Resources Conservation Service highlight the importance of sustainable water management practices in mitigating climate change impacts.
As a part of the St. Paul District, Silver Creek Watershed Dt #4 contributes to the overall water resource management efforts in the state. With a drainage area of 2 square miles and a maximum discharge capacity of 1350 cubic feet per second, the dam plays a crucial role in protecting downstream communities from potential flooding events. With its strategic location and design, this dam serves as a vital asset in maintaining water security and climate resilience in the Silver Creek watershed.

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.
