Seven Oaks dam
Seven Oaks
Seven Oaks is a rockfill dam located in Yucaipa, California, along the Santa Ana River. Completed in 1999, this dam stands at a height of 550 feet with a storage capacity of 145,600 acre-feet. Its primary purpose is flood risk reduction, serving as a crucial structure in protecting the surrounding area from potential inundation during heavy rainfall events. The dam is regulated by the California Department of Water Resources and undergoes regular inspections to ensure its structural integrity.
With a high hazard potential but a satisfactory condition assessment as of September 2017, Seven Oaks plays a vital role in water resource management and climate resilience in the region. The dam's design and construction reflect a commitment to safeguarding the community from flooding and mitigating potential risks associated with its operation. The dam's strategic location and storage capacity contribute to the overall flood risk reduction efforts in the area, making it an essential component of the local water infrastructure.
Managed by the local government, Seven Oaks serves as a testament to the collaborative efforts of various agencies and stakeholders in addressing water resource challenges. Its presence highlights the importance of proactive measures in adapting to climate change impacts and ensuring the safety and security of the surrounding communities. As a key asset in flood risk reduction, Seven Oaks stands as a symbol of resilience and preparedness in the face of evolving environmental conditions.
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 Seven Oaks
Where does the data for Seven Oaks 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.
