Trail Bridge Saddle Dike dam
Trail Bridge Saddle Dike
Trail Bridge Saddle Dike is a significant structure located in Linn, Oregon, along the McKenzie River. Built in 1963 by the Bechtel Corporation, this earth dam stands at a height of 35 feet and spans a length of 1000 feet. With a primary purpose of hydroelectric power generation, the dam also serves recreational activities in the area.
Owned by a public utility, Trail Bridge Saddle Dike is regulated by the Federal Energy Regulatory Commission and undergoes inspections by the same agency. With a storage capacity of 2263 acre-feet and a hazard potential rated as high, the dam plays a crucial role in managing water resources in the region. The dam's location at T15S, R6E, S11, WM, makes it a key infrastructure for water management in Oregon.
Although the condition assessment of Trail Bridge Saddle Dike is not currently available, its risk assessment is rated as high. Emergency action plans are in place, but details on their preparation and guidelines adherence are not specified. With its importance for hydroelectric power generation and water resource management, Trail Bridge Saddle Dike stands as a vital structure in the region, closely monitored for any potential risks or hazards.
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 Trail Bridge Saddle Dike
Where does the data for Trail Bridge Saddle Dike 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.
