Summary
Built in 1925 by the Bureau of Reclamation, this federal-owned structure serves primarily for irrigation purposes, with a storage capacity of 130,270 acre-feet and a maximum discharge of 900 cubic feet per second. The dam stands at an impressive height of 88 feet, with a hydraulic height of 70 feet and a length of 485 feet, making it a significant water resource in the Klamath County area.
Managed and regulated by the Bureau of Reclamation, Gerber has a high hazard potential due to its size and location. Despite its age, the dam's condition assessment is currently listed as "Not Available," highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality. Located in a picturesque setting with a surface area of 3830 acres, Gerber plays a crucial role in water management and irrigation for the surrounding region, showcasing the importance of sustainable water resource management in the face of climate change and increasing water demands.
As a key piece of infrastructure in the area, Gerber serves as a vital resource for water supply and agricultural needs in Oregon. With its historical significance and essential role in supporting the local ecosystem, efforts to maintain and safeguard the dam are essential for ensuring the continued availability of water resources in the region. For water resource and climate enthusiasts, Gerber stands as a testament to the importance of responsible water management and the need for ongoing investment in infrastructure to address the challenges posed by 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.
