Summary
With a structure height of 34 feet and a hydraulic height of 27 feet, this dam plays a crucial role in protecting the area from potential flooding events. The dam has a storage capacity of 526 acre-feet, with a normal storage capacity of 15 acre-feet, covering a surface area of 6 acres and draining an area of 1.5 square miles.
Managed by the Nebraska Department of Natural Resources, Swedeburg 2b-1 undergoes regular inspections every five years, with its last assessment in May 2016 deeming it to be in satisfactory condition and posing a low hazard potential. The dam has not been modified over the years and does not have an Emergency Action Plan (EAP) in place. While it has not faced any significant risk assessment or risk management measures, its role in flood risk reduction remains crucial for the local community. With the support of local and federal agencies, including the Natural Resources Conservation Service, Swedeburg 2b-1 continues to serve as a vital infrastructure for water resource management in Saunders, Nebraska.

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.
