Yamhill Vista Dam #5 dam
Yamhill Vista Dam #5
Yamhill Vista Dam #5, located in Yamhill, Oregon, is a private-owned earth dam designed by Stuntzner Engineering & Forestry for irrigation purposes. 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.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Yamhill Vista Dam #5
Where does the data for Yamhill Vista Dam #5 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
