Summary
Built in 1978 by the USDA NRCS, this earth dam stands at a height of 43 feet and has a maximum storage capacity of 155 acre-feet. With a drainage area of 0.6 square miles and a normal storage of 64 acre-feet, the dam plays a crucial role in managing water resources in the region.
Owned by the local government and regulated by the Nebraska Department of Natural Resources, Winnebago Creek 42-3a is in satisfactory condition with a low hazard potential. The dam spans 599 feet in length and covers a surface area of 5 acres. While it has not been modified in recent years, regular inspections are conducted to ensure its structural integrity and safety. With a maximum discharge capacity of 239 cubic feet per second, the dam serves as a vital infrastructure for flood control and water resource management in the area.
Despite its low hazard potential, Winnebago Creek 42-3a remains a key asset for the community, providing protection against potential flooding events and supporting the sustainable use of water resources. As climate change continues to impact weather patterns and water availability, the proper maintenance and monitoring of dams like Winnebago Creek 42-3a are essential for ensuring the resilience of local water systems in the face of evolving environmental 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.
