Summary
This private dam stands at a height of 35 feet and stretches 570 feet in length, providing a storage capacity of 95 acre-feet. While its hazard potential is classified as low, the condition assessment is marked as "Not Available" with no recent inspection data provided. Despite its age, the dam remains a crucial resource in managing water resources for agricultural needs in the region.
Owned and operated by a private entity, Dejong Dam is regulated by the USDA NRCS and has no associated federal agencies for funding or construction. Being an earth dam, it serves as a vital infrastructure for maintaining water supply for the surrounding area. Although detailed information on its current condition is lacking, the dam's low hazard potential suggests that it is being adequately managed to ensure safety and efficiency in irrigation operations. As a key player in water resource management in Polk County, Dejong Dam plays a significant role in sustaining agricultural activities and supporting the local economy.
Despite the limited information available on its condition and maintenance, Dejong Dam continues to serve as a vital water resource infrastructure in Oregon. With a focus on irrigation, this earth dam has been a reliable source of water storage since its completion over six decades ago. As climate change poses challenges to water availability, Dejong Dam remains a crucial asset in ensuring sustainable water management practices for the agricultural community in the region.

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.
