Fern Ridge Dam - Dike 1 dam
Fern Ridge Dam - Dike 1
Fern Ridge Dam - Dike 1, located in Eugene, Oregon, is a federal structure owned and managed by the US Army Corps of Engineers. This dam, with a height of 8 feet and a length of 800 feet, serves the primary purpose of flood risk management and water storage. With a storage capacity of 9774 acre-feet, the dam plays a crucial role in regulating water levels and mitigating flood risks in the region.
Despite being classified as having a low hazard potential, the US Army Corps of Engineers actively monitors and manages the dam's condition to ensure its structural integrity and effectiveness in flood control. The agency engages with local emergency managers and the public to raise awareness about the dam, develop emergency action plans, and coordinate response efforts in the event of a dam-related emergency. Regular maintenance and repairs are conducted to keep the dam functioning properly and reduce risks associated with severe weather events and potential dam releases.
As part of ongoing risk management measures, the US Army Corps of Engineers continues to assess and address flood risks associated with Fern Ridge Dam - Dike 1. By prioritizing activities that reduce potential risks and collaborating with local stakeholders, the agency works towards ensuring the safety and resilience of the dam and surrounding communities in the face of changing climate conditions and increasing water resource challenges.
Dam data reference
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 Fern Ridge Dam - Dike 1
Where does the data for Fern Ridge Dam - Dike 1 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.
