Summary
This privately owned earth dam stands at a height of 25.4 feet and has a storage capacity of 35.1 acre-feet, providing crucial protection to the surrounding area. With a low hazard potential and a condition assessment that is currently not rated, Little Dam 3322 is a key infrastructure for managing water resources in the region.
Managed by the Nebraska Department of Natural Resources, Little Dam 3322 undergoes regular inspections to ensure its structural integrity and functionality. With a drainage area of 0.06 square miles and a normal storage capacity of 13 acre-feet, this dam plays a vital role in mitigating the impact of potential flooding events. While the dam has not been modified in recent years and lacks specific spillway details, its presence is essential for safeguarding the local community from water-related risks.
Congressional District 03, Nebraska, represented by Adrian Smith, relies on the protection provided by Little Dam 3322 to manage the flow of Turkey Creek and prevent potential flooding disasters. As climate change continues to impact water resources, the importance of dams like Little Dam 3322 in flood risk reduction and water management strategies becomes increasingly significant. This privately owned structure stands as a testament to the collaborative efforts between state agencies and private owners in safeguarding communities against the challenges of a changing climate.

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.
