Summary
Completed in 1923, this earth dam stands at a height of 32 feet and has a storage capacity of 500 acre-feet, serving the agricultural needs of the region. With a low hazard potential, the dam plays a crucial role in water management and resource allocation in the Klamath County area.
Operated and maintained by the Bureau of Reclamation, Malone Diversion is a vital infrastructure for water supply and irrigation purposes. Its strategic location and design allow for efficient water diversion and storage, benefiting the local farmers and communities dependent on the Lost River for agricultural activities. Despite its age, the dam continues to operate effectively, reflecting the sound engineering principles employed by the Bureau of Reclamation during its construction.
With a focus on irrigation, Malone Diversion exemplifies the importance of water resource management in the face of changing climate patterns. As water resources become increasingly scarce, structures like Malone Diversion play a critical role in ensuring sustainable water supply for agricultural activities while mitigating the impacts of drought and water scarcity in the region. As climate enthusiasts and water resource advocates, understanding and appreciating the significance of infrastructure like Malone Diversion is essential in promoting resilience and sustainability in the face of climate challenges.

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.
