Summary
Built in 1985 by the USDA NRCS, this earth dam stands at 33 feet high with a hydraulic height of 30.68 feet, serving the primary purpose of flood risk reduction. The dam has a storage capacity of 1262 acre-feet and a drainage area of 7.5 square miles, helping to mitigate potential flooding in the area.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Blackwood Creek 32-A has a low hazard potential and is deemed to be in satisfactory condition as of its last inspection in July 2018. The dam spans 550 feet in length and covers a surface area of 17 acres. With a normal storage capacity of 61 acre-feet and a maximum discharge rate of 2345 cubic feet per second, this structure plays a crucial role in protecting the surrounding community from flooding events.
Situated in the Omaha District and overseen by the Natural Resources Conservation Service, Blackwood Creek 32-A is a vital component of the region's water resource management infrastructure. With its effective flood risk reduction capabilities and satisfactory condition assessment, this dam stands as a testament to the importance of proactive climate and water resource management in safeguarding communities against potential natural disasters.

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.
