Scoggins dam
Scoggins
Scoggins is a fascinating water resource in Forest Grove, Oregon, managed by the Bureau of Reclamation for irrigation purposes. The dam, completed in 1974, stands at an impressive 151 feet in height and holds a storage capacity of 62,540 acre-feet. This earth dam, located on Scoggins Creek, is crucial for providing water supply to the region and covers a surface area of 1,157 acres.
With a high hazard potential and very high risk assessment, Scoggins Dam has undergone modifications in 2004 to enhance its mechanical and seismic resilience. The controlled spillway, with a width of 38 feet, plays a crucial role in managing water discharge during high-flow events. Despite its critical importance, the condition assessment of the dam is currently not available, highlighting the need for ongoing monitoring and maintenance to ensure its structural integrity and safety.
Managed by the Bureau of Reclamation, Scoggins Dam is a vital infrastructure for water management in the region, serving both irrigation and water supply purposes. With its rich history dating back to the 1970s, this dam continues to play a significant role in supporting agricultural activities and water needs in the area. As a key player in the water resource management landscape, Scoggins Dam's resilience and operational efficiency are essential for safeguarding the surrounding communities and ecosystems against potential hazards and risks.

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 Scoggins
Where does the data for Scoggins 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.
