Summary
The reservoir was completed in 1967 and has a storage capacity of 72 acre-feet, covering a surface area of 14 acres. It is situated along Salt Creek and Ash Swale, providing essential water supply for agricultural activities in the region. The dam, constructed from concrete, stands at a height of 10 feet and spans a length of 40 feet.
Managed by the Oregon Water Resources Department, Lancefield Reservoir is regulated, inspected, and enforced by state authorities to ensure its structural integrity and safe operation. Despite its low hazard potential, the reservoir undergoes regular inspections every 6 years to assess its condition. The last inspection was conducted in June 2017, with a hazard potential rating of "Low" and a condition assessment of "Not Rated." The reservoir plays a crucial role in supporting the local agricultural community and maintaining water resources in the area.
With its strategic location and reliable water supply, Lancefield Reservoir serves as a vital resource for sustaining irrigation needs in Whiteson, Oregon. Although not federally owned or funded, the reservoir contributes significantly to the agricultural sector in the region. Climate enthusiasts and water resource professionals can appreciate the reservoir's importance in water management, drought resilience, and supporting sustainable agricultural practices in the area.

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.
