Summary
Completed in 1980, this Earth type dam stands at a height of 16 feet with a length of 400 feet, providing a storage capacity of 142 acre-feet. The dam's primary purpose is to support the conservation of fish and wildlife in the area, with a normal storage level of 23 acre-feet and a surface area of 8 acres.
Managed by the Nebraska Department of Natural Resources, this dam has a low hazard potential and is deemed to be in satisfactory condition as of the last inspection in 2018. The dam has undergone modifications in 2003 to enhance its hydraulic capabilities. With a drainage area of 14.7 square miles and a maximum discharge capacity of 176 cubic feet per second, the Gracie Creek Road Dam plays a crucial role in regulating water flow and supporting the local ecosystem.
As a vital component of water resource management in the area, the Gracie Creek Road Dam contributes to the overall environmental health and sustainability of the region. Its presence ensures the protection and enhancement of fish and wildlife habitats, while also serving as a key infrastructure for flood control and water management. With its strategic location and functionality, this dam stands as a testament to the importance of sustainable water resource practices in maintaining a balanced and resilient ecosystem.

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.
