Summary
This dam serves multiple purposes including flood risk reduction and other water resource management functions. With a height of 25 feet and a length of 1125 feet, Ziegler Creek Z-1 has a storage capacity of 106 acre-feet and a drainage area of 0.7 square miles, contributing to the regulation of the TR-Little Nemaha River.
Managed by the local government and regulated by the NE DNR, Ziegler Creek Z-1 has a low hazard potential and fair condition assessment as of the last inspection in May 2016. Despite its age, the dam continues to play a crucial role in water management and climate resilience efforts in the region. With a focus on maintaining its functionality and safety, Ziegler Creek Z-1 stands as a testament to effective water resource infrastructure in Nebraska.
Situated within the Kansas City District and under the jurisdiction of the state, Ziegler Creek Z-1 exemplifies the collaborative efforts between federal, state, and local agencies in managing water resources. As climate change impacts intensify, infrastructure like Ziegler Creek Z-1 will be essential in mitigating flood risks and ensuring sustainable water management practices for the community.

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.
