Summary
It serves as a Fish and Wildlife Pond, with a primary purpose of supporting aquatic life in the area. The dam stands at a height of 33 feet and has a length of 1134 feet, providing a storage capacity of 16 acre-feet.
Managed by the Nebraska Department of Natural Resources, Graham Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. Despite being classified as low hazard potential, the dam is in satisfactory condition based on the last assessment conducted in June 2020. The structure plays a crucial role in maintaining the ecological balance of TR-Hooker Creek and its surrounding environment.
Enthusiasts of water resources and climate will find Graham Dam an intriguing site, not only for its engineering and design aspects but also for its contribution to supporting fish and wildlife populations in the region. With its functional design, regulatory oversight, and positive impact on the local ecosystem, Graham Dam stands as a testament to responsible water resource management in Nebraska.

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.
