Sarvis dam
Sarvis
Sarvis Dam, also known as Mainline 2, is a privately owned structure located in Crook County, Oregon. Completed in 1970, this earth dam stands at a height of 36 feet and has a storage capacity of 55 acre-feet, primarily used for irrigation purposes along Sarvis Creek. With a drainage area of 1.9 square miles and a maximum discharge of 766 cubic feet per second, Sarvis Dam plays a crucial role in managing water resources in the region.
Despite being regulated by the Oregon Water Resources Department and undergoing regular inspections, Sarvis Dam is classified as having a significant hazard potential. The dam features a slide gate outlet and an uncontrolled spillway, emphasizing the need for careful monitoring and maintenance to ensure the safety of downstream communities. With a moderate risk assessment rating, stakeholders and climate enthusiasts are encouraged to stay informed about Sarvis Dam's condition and any potential risk management measures that may be implemented in the future.
Overall, Sarvis Dam serves as a vital infrastructure for water management in the area, highlighting the intersection of water resource management and climate resilience. As enthusiasts continue to monitor its condition and risk assessment, the importance of sustainable and proactive measures to address potential hazards becomes increasingly apparent. Sarvis Dam stands as a testament to the ongoing efforts to balance water resource utilization with environmental protection in the face of changing climatic conditions.

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.
Plan around the weather

About Sarvis
Where does the data for Sarvis 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.
