Eagle Lake Dam dam
Eagle Lake Dam
Eagle Lake Dam, also known as Eagle Lake Reservoir, is a privately owned structure located in Union, Oregon. Completed in 1920, this earth dam stands at a height of 33 feet and serves primarily for irrigation purposes. With a storage capacity of 844 acre-feet and a surface area of 35.3 acres, Eagle Lake Dam holds back the waters of the Eagle Lake stream, providing essential water resources for the surrounding area.
Managed by the Oregon Water Resources Department, Eagle Lake Dam is regulated, inspected, and enforced by the state to ensure its safety and functionality. The dam features a slide (sluice gate) outlet gates and has a low hazard potential. Despite not being rated for condition assessment, the dam is subject to regular inspections every six years to maintain its integrity. Located within the Walla Walla District, Eagle Lake Dam plays a vital role in water resource management and irrigation in the region.
As a key component of the water infrastructure in the area, Eagle Lake Dam plays a crucial role in managing water resources for agricultural purposes. With its historical significance dating back to the early 20th century, the dam continues to provide essential water storage and distribution for the local community. As climate change impacts water availability, the maintenance and regulation of Eagle Lake Dam remain vital for ensuring a sustainable water supply in the region.

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 Eagle Lake Dam
Where does the data for Eagle Lake Dam 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 Low 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.
