Summary
Completed in 2017, this earth dam stands at a height of 23.75 feet with a storage capacity of 130 acre-feet. The dam is state-permitted, inspected, and enforced, ensuring its compliance with safety regulations and its ability to mitigate flood risks in the area.
This significant dam, with a hazard potential rating of "Significant," plays a crucial role in water management and flood control in the region. While the condition assessment is currently "Not Rated," regular inspections are conducted to ensure the structure's integrity and safety. The dam's emergency action plan status and risk management measures are not specified, but its role in protecting the community from potential inundation events underscores its importance in water resource management and climate resilience efforts in Yamhill County.
As a key part of the local water infrastructure, Jensen (Yamhill Farm) serves as a vital resource for water storage and flood protection in Oregon. Its presence highlights the importance of sustainable water resource management and the need for continued monitoring and maintenance to ensure its functionality and safety for the surrounding community.

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.
