Agate dam
Agate
Agate Dam, also known as A-18, is a federal-owned structure located in White City, Oregon. Built in 1965 by the Bureau of Reclamation, this rockfill dam stands at a height of 77 feet and serves primarily for irrigation purposes in the region. With a storage capacity of 5700 acre-feet and a normal storage level of 4780 acre-feet, Agate Dam plays a crucial role in managing water resources for agriculture in the area.
Situated on Dry Creek, Antelope Creek, and other water bodies, Agate Dam covers a surface area of 216 acres and has a drainage area of 10 square miles. The dam's maximum discharge capacity is 3530 cubic feet per second, ensuring effective flood control measures in times of heavy rainfall. Despite its high hazard potential, the condition assessment of Agate Dam is currently not available, highlighting the importance of regular inspections and risk management measures to ensure the safety and functionality of this vital water infrastructure.
Managed and operated by the Bureau of Reclamation, Agate Dam stands as a testament to the agency's commitment to water resource management and irrigation development in the region. With its strategic location and significant storage capacity, Agate Dam continues to play a crucial role in supporting agricultural activities and water supply for the local community. As climate change impacts water availability and distribution, structures like Agate Dam will be essential for sustainable water management practices in the face of evolving environmental challenges.

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 Agate
Where does the data for Agate 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 High 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.
