Dejong Dam dam
Dejong Dam
Dejong Dam, located in Amity, Oregon, was completed in 1961 and is primarily used for irrigation purposes along the Tr- Salt Creek. This private dam stands at a height of 35 feet and stretches 570 feet in length, providing a storage capacity of 95 acre-feet. While its hazard potential is classified as low, the condition assessment is marked as "Not Available" with no recent inspection data provided. Despite its age, the dam remains a crucial resource in managing water resources for agricultural needs in the region.
Owned and operated by a private entity, Dejong Dam is regulated by the USDA NRCS and has no associated federal agencies for funding or construction. Being an earth dam, it serves as a vital infrastructure for maintaining water supply for the surrounding area. Although detailed information on its current condition is lacking, the dam's low hazard potential suggests that it is being adequately managed to ensure safety and efficiency in irrigation operations. As a key player in water resource management in Polk County, Dejong Dam plays a significant role in sustaining agricultural activities and supporting the local economy.
Despite the limited information available on its condition and maintenance, Dejong Dam continues to serve as a vital water resource infrastructure in Oregon. With a focus on irrigation, this earth dam has been a reliable source of water storage since its completion over six decades ago. As climate change poses challenges to water availability, Dejong Dam remains a crucial asset in ensuring sustainable water management practices for the agricultural community 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 Dejong Dam
Where does the data for Dejong 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.
