Summary
Completed in 1980, this private earth dam stands at a height of 14.7 feet and has a storage capacity of 74.8 acre-feet, with a normal storage level of 15 feet. Despite its low hazard potential, the dam is currently assessed as being in poor condition, highlighting the importance of regular inspections and maintenance to ensure its continued effectiveness in mitigating flood risks in the area.
Owned by a private entity, Wissing Dam falls under the jurisdiction of the Nebraska Department of Natural Resources (DNR) for regulation, permitting, inspection, and enforcement. The dam's primary purpose remains flood risk reduction, with a structural length of 300 feet and a surface area of 4.6 acres. While the dam has not undergone significant modifications in recent years, its last inspection in September 2020 revealed the need for attention to its condition, emphasizing the importance of proactive risk management measures to safeguard the surrounding community and environment.
As climate change continues to impact water resources and weather patterns, the resilience and maintenance of structures like Wissing Dam become increasingly crucial. With a designated inspection frequency of five years and an associated emergency action plan yet to be prepared, ongoing monitoring and preparedness efforts are essential to ensure the safety and functionality of this vital infrastructure in the face of evolving climate-related 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.
