Foster Log Pond dam
Foster Log Pond
Foster Log Pond, also known as Willamette National Log Pond, is a privately owned water storage facility located in Linn County, Oregon. Built in 1946, this Earth dam stands at 17 feet tall and has a storage capacity of 375 acre-feet. Situated along the South Santiam River, the pond covers a surface area of 57 acres and serves multiple purposes beyond just water storage.
With a high hazard potential and fair condition assessment, Foster Log Pond is regularly inspected by the Oregon Water Resources Department to ensure its structural integrity and safety. Equipped with slide gates for outlet control, this dam plays a crucial role in managing water flow and storage for its surrounding area. While it may not have a spillway or locks, its strategic location and design make it a significant feature in the local water resource infrastructure.
For water resource and climate enthusiasts, Foster Log Pond offers a glimpse into the intricate network of dams and reservoirs that contribute to water management in Oregon. Its presence along the South Santiam River highlights the importance of these structures in regulating water flow, mitigating flood risks, and supporting various environmental and agricultural activities in the region. As a privately owned facility with state regulation and inspection, Foster Log Pond exemplifies the collaboration between private entities and government agencies to ensure sustainable water resource management in the face of changing climate conditions.

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 Foster Log Pond
Where does the data for Foster Log Pond 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.
