New Woodbridge Diversion dam
New Woodbridge Diversion
The New Woodbridge Diversion, also known as Lodi Lake, is a vital water resource infrastructure located in Woodbridge, California. Completed in 2006, this public utility serves multiple purposes, including flood risk reduction and irrigation, along the Mokelumne River. With a dam height of 31 feet and a storage capacity of 1,583 acre-feet, the diversion plays a significant role in managing water resources in the region.
Managed by the California Department of Water Resources and regulated by the Safety of Dams program, the New Woodbridge Diversion has a satisfactory condition assessment and a significant hazard potential. The dam spans 600 feet in length and covers a surface area of 474 acres, offering crucial protection against potential flood events. Furthermore, with state-permitting, inspection, and enforcement in place, the facility ensures operational safety and compliance with regulatory standards.
As a key component of the flood risk reduction strategy in San Joaquin County, the New Woodbridge Diversion stands as a testament to effective water resource management and infrastructure development. With its strategic location, storage capacity, and regulatory oversight, this essential structure plays a crucial role in safeguarding communities and supporting agricultural activities in the region. Climate and water resource enthusiasts can appreciate the engineering marvel and environmental significance of the New Woodbridge Diversion in sustaining water security and resilience 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.

About New Woodbridge Diversion
Where does the data for New Woodbridge Diversion 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 Significant 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.
