Summary
Constructed in 1964 by the USDA NRCS, this private-owned earth dam stands at a height of 26 feet and spans 220 feet in length. With a storage capacity of 130 acre-feet and a normal storage of 58 acre-feet, the dam plays a significant role in managing water resources in the area.
Managed by the Nebraska Department of Natural Resources, Alfred James Detention Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. Despite being classified with a low hazard potential and fair condition assessment, the dam undergoes regular inspections every five years to monitor its performance. Its location in a rural setting underscores its importance in protecting the surrounding community from potential flooding events.
With its primary purpose being flood risk reduction, Alfred James Detention Dam also serves other functions in water resource management. Supported by the Natural Resources Conservation Service, the dam exemplifies the collaborative efforts between private owners and government agencies in safeguarding local communities against the impacts of extreme weather events and climate change.

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.
