Summary
This earth dam stands at a height of 53.8 feet and has a storage capacity of 17,745 acre-feet, serving its primary purpose effectively. Despite its age, the dam's condition is assessed as poor, with a high hazard potential, highlighting the need for regular inspections and maintenance to ensure its continued functionality.
Managed by the Nebraska Department of Natural Resources, Spring Creek 19-B is regulated, permitted, inspected, and enforced by the state to uphold safety standards. The dam's location in the TR-Spring Creek watershed contributes to its significance in managing water resources and protecting downstream areas from potential flooding. With a drainage area of 67.25 square miles and a maximum discharge capacity of 20,244 cubic feet per second, the dam plays a critical role in flood control within the region.
As an essential infrastructure in flood risk management, Spring Creek 19-B's operational and maintenance status requires attention to address its poor condition assessment. With a history of serving its purpose since its completion, the dam underscores the importance of proactive measures to ensure its continued effectiveness in safeguarding communities and natural resources from the impacts of extreme weather events and changing climate patterns in the future.

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.
