Cucamonga Creek Debris Basin dam
Cucamonga Creek Debris Basin
Located in San Bernardino, California, the Cucamonga Creek Debris Basin is a crucial structure designed for debris control and flood risk reduction. Owned by the local government, this Earth dam stands at a height of 60 feet and spans a length of 2980 feet, with a storage capacity of 355 acre-feet. Completed in 1980, it serves the primary purpose of managing debris in the Cucamonga Creek, which covers a drainage area of 12.35 square miles.
With a high hazard potential, the Cucamonga Creek Debris Basin undergoes regular inspections to ensure its structural integrity. The latest assessment in 2017 deemed its condition satisfactory, highlighting its importance in mitigating potential risks in the region. As part of the state-regulated facilities, it falls under the oversight of the Department of Water Resources (DWR) and is subject to state permitting, inspection, and enforcement to maintain its operational effectiveness in managing debris and reducing flood risks in the area.
Supported by federal and state agencies, the Cucamonga Creek Debris Basin plays a vital role in safeguarding the San Antonio community from potential flooding events. With its strategic location and effective design, this structure stands as a testament to the collaborative efforts between local and state entities in managing water resources and climate-related challenges in California.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Cucamonga Creek Debris Basin
Where does the data for Cucamonga Creek Debris Basin 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.
