Summary
This private earth dam stands at a height of 14 feet and stretches 366 feet in length, completed in 1955. With a storage capacity of 105.4 acre-feet, this dam plays a crucial role in managing water resources in the region, offering a normal storage capacity of 4.1 acre-feet and covering a surface area of 2.5 acres.
Managed by the Nebraska Department of Natural Resources, Winter Dam is state-regulated and inspected regularly to ensure its structural integrity and safety. With a low hazard potential, the dam's condition assessment is currently not rated, but it remains a key asset in the local water management infrastructure. The dam's location in Dawson County, Nebraska, underscores its importance in providing water security and supporting various local ecosystems.
As a focal point for water resource and climate enthusiasts, Winter Dam's role in the region extends beyond its primary purposes. With its strategic location and significant storage capacity, this dam is a vital component in the management of water resources in Nebraska. Its presence along the Wood River not only provides essential services for fire protection and agricultural activities but also contributes to the overall ecological balance in the area.

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.
