Summary
Completed in 2008, the primary purpose of this dam is flood risk reduction, contributing to the protection of the surrounding area from potential water-related disasters. With a height of 9 feet and a drainage area of 47.4 square miles, this dam plays a crucial role in managing water flow and minimizing flood risks in the region.
Despite its relatively low hazard potential, Silver Creek Lowland Detention Dam 5 is regularly inspected by the Nebraska Department of Natural Resources, with a satisfactory condition assessment as of June 2019. The dam has a maximum storage capacity of 2345.4 acre-feet and a maximum discharge capacity of 1161 cubic feet per second, highlighting its effectiveness in flood control measures. Situated within the Congressional District 03 of Nebraska, this dam serves as a vital infrastructure for water resource management and climate resilience in the area.
In the event of an emergency, it is essential for the local authorities to have an updated emergency action plan (EAP) in place, although specific details regarding the preparation and implementation of such a plan for Silver Creek Lowland Detention Dam 5 are not provided in the available data. Overall, this dam stands as a testament to proactive flood risk reduction efforts, emphasizing the importance of sustainable water resource management and climate adaptation in the face of changing environmental conditions.

Dam Data Reference
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.
