Summary
With a structural height of 36 feet and a dam length of 598 feet, this dam serves multiple purposes including flood risk reduction and other functions. It has a storage capacity of 209 acre-feet and a normal storage of 72 acre-feet, covering a surface area of 8 acres and draining a 0.5 square mile watershed.
Managed by the local government and regulated by the NE DNR, Winnebago Creek 43-2 has a low hazard potential and is currently in satisfactory condition as of the last inspection in April 2018. The dam's primary source agency is the state of Nebraska, with state permitting, inspection, and enforcement in place. Located in the vicinity of the Winnebago Creek, this structure plays a crucial role in mitigating flood risks and managing water resources in the region.
Enthusiasts of water resources and climate will find Winnebago Creek 43-2 an intriguing case study in dam engineering and management. With its earth construction and stone core, this dam exemplifies the intersection of human infrastructure and natural water systems. Its presence in the Omaha District underscores the importance of effective dam regulation and maintenance for sustainable water resource management in the face of changing climate 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.
