Summary
The dam stands at a height of 27 feet along the Stag Hollow Creek and is regulated by the Oregon Water Resources Department. With a significant hazard potential, the dam has not been rated for its current condition as of the last inspection in December 2019.
Despite its primary purpose for irrigation, Yamhill Vista Dam #5 also serves fire protection, stock, small fish pond, fish and wildlife pond, and recreational uses. The dam does not have associated structures and is not under the jurisdiction of any federal agency, making it solely regulated at the state level. With a 3-year inspection frequency and no Emergency Action Plan in place, there is a need for continued monitoring and risk assessment to ensure the safety and functionality of the dam.
Water resource and climate enthusiasts will find Yamhill Vista Dam #5 an interesting subject for study as it plays a crucial role in water management and conservation efforts in the region. With its location in a picturesque area of Yamhill County and its diverse purposes, the dam presents a unique opportunity to explore the intersection of human infrastructure with natural ecosystems. As ongoing assessments and management measures are implemented, the dam serves as a focal point for understanding the complexities of balancing water resource needs with environmental considerations in 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.
