Summary
This private dam stands at a height of 30 feet with a hydraulic height of 30 feet and a structural height of 34 feet. With a storage capacity of 428.8 acre-feet and a normal storage level of 99.4 acre-feet, Grevson Dam covers a surface area of 17.4 acres and drains an area of 6 square miles.
Managed by the Nebraska Department of Natural Resources, Grevson Dam is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. With a low hazard potential and a satisfactory condition assessment as of November 2019, the dam has a regular inspection frequency of every 5 years. Despite being a private structure, Grevson Dam plays a vital role in water resource management and climate resilience in the region, providing essential services to the local community while maintaining a minimal risk profile.
Surrounded by the picturesque landscape of Sand Creek and under the jurisdiction of the Omaha District, Grevson Dam stands as a testament to the collaboration between private and government entities in safeguarding water resources. With its earth core and stone foundation, this essential infrastructure symbolizes the importance of sustainable water management practices in the face of changing climatic conditions. As a key component of the local ecosystem, Grevson Dam exemplifies the intersection of human ingenuity and environmental stewardship in ensuring water security for future generations.

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.
