Arundell Barranca dam
Arundell Barranca
Arundell Barranca, located in Ventura, California, is a vital structure designed for debris control and flood risk reduction purposes. This earth dam stands at a height of 57 feet and has a hydraulic height of 49 feet, completed in 1996. With a storage capacity of 155 acre-feet and a drainage area of 2.71 square miles, it plays a crucial role in managing water resources in the region.
Managed by the local government and regulated by the Department of Water Resources (DWR) for safety compliance, Arundell Barranca has a high hazard potential but is currently assessed to be in satisfactory condition. The dam's last inspection in September 2020 confirmed its structural integrity, ensuring its effectiveness in mitigating flood risks for the surrounding area. With a solid track record of meeting regulatory standards, this dam serves as a key resource in safeguarding the community and environment from potential water-related disasters.
As a significant component of flood control infrastructure in Ventura, Arundell Barranca stands as a testament to effective water resource management. Its strategic location and design contribute to the overall resilience of the region against natural disasters, highlighting the importance of proactive dam maintenance and regulatory oversight. With a commitment to safety and operational efficiency, this structure plays a critical role in ensuring water security and climate resilience for the community it serves.
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 Arundell Barranca
Where does the data for Arundell Barranca 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.
