Summary
Built in 1999 and owned by the local government, this earth dam stands at a height of 44 feet, with a hydraulic height of 43 feet and a structural height of 54 feet. With a normal storage capacity of 250 acre-feet and a maximum discharge of 30,806 cubic feet per second, this dam plays a crucial role in protecting the surrounding area from potential flooding.
Managed by the Nebraska Department of Natural Resources, Weeping Water Creek 8-A has been deemed to have a low hazard potential and is currently in satisfactory condition according to the latest assessment in November 2020. The dam covers a surface area of 55 acres and serves a drainage area of 13.9 square miles. With its primary purpose being flood risk reduction, this structure plays a key role in safeguarding the local community of Rural Elmwood and beyond from the impacts of extreme weather events and rising water levels in the Weeping Water Creek.
Furthermore, the dam is situated within Congressional District 01, Nebraska, represented by Jeff Fortenberry (R). With state regulation, permitting, inspection, and enforcement in place, Weeping Water Creek 8-A exemplifies the collaborative effort between local and state agencies to ensure the effective management and maintenance of critical water resource infrastructure. As a significant component of the water management system in the region, this dam stands as a testament to the proactive approach taken to mitigate flood risks and protect the environment and communities along Weeping Water Creek.

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.
