Summary
Completed in 1995, it stands at a height of 35 feet with a structural height of 36 feet and a length of 570 feet. The dam serves the primary purpose of flood risk reduction along the TR-South Cedar Creek, with a storage capacity of 148 acre-feet and a drainage area of 0.6 square miles.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Weeping Water Creek 17-L has been assessed as being in satisfactory condition with a significant hazard potential. Despite its critical role in mitigating flood risks, the dam lacks detailed spillway information and emergency action plans as of the last inspection in May 2018. With a maximum discharge capacity of 1285 cubic feet per second, it remains a key structure in safeguarding the surrounding area from potential flooding events.
As a key component of flood management in the region, Weeping Water Creek 17-L serves as a vital infrastructure for local residents and businesses. With its location along a major waterway, the dam's maintenance and emergency preparedness are crucial for ensuring the safety and resilience of the community in the face of changing climate patterns and water resource challenges.

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.
