Summary
Completed in 1980, this earth dam with a height of 22.3 feet serves to protect the surrounding area from potential inundation by providing storage for excess water during periods of heavy rainfall. With a normal storage capacity of 32.3 acre-feet and a maximum storage capacity of 55.3 acre-feet, the dam plays a vital role in managing water levels and mitigating flood hazards in the region.
Despite its importance for flood control, Schwanz Dam 3507 is currently assessed to be in poor condition, with a low hazard potential. The dam's structural integrity and overall functionality are crucial aspects that need attention to ensure its continued effectiveness in safeguarding the area from flooding events. With the Nebraska Department of Natural Resources (NE DNR) as the state regulatory agency overseeing its operations, inspections, and enforcement, efforts are likely being made to address the dam's condition and implement necessary maintenance measures. As climate change continues to impact water resources and weather patterns, the maintenance and upkeep of dams like Schwanz Dam 3507 become increasingly vital in ensuring the resilience of communities against the threat of floods.

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.
