Weber dam
Weber
Weber Dam, located in El Dorado, California, is a multi-arch dam completed in 1924 for water supply purposes, specifically for irrigation and water supply. The dam stands at a height of 92 feet and has a hydraulic height of 87.9 feet, with a storage capacity of 1100 acre-feet and a surface area of 41 acres. The dam is situated on the Nfk Weber Creek and is regulated by the California Department of Water Resources (DWR) for safety and inspection.
The high hazard potential of Weber Dam is closely monitored, with regular inspections conducted to ensure its satisfactory condition. The dam is state-regulated, with permitting, inspection, and enforcement measures in place to maintain its safety and integrity. The last inspection in March 2021 confirmed its satisfactory condition, and emergency action plans are in place to address any potential risks. With its strategic location and significant role in water resource management, Weber Dam plays a crucial role in supporting the water supply needs of the area.
Weber Dam's historical significance, structural design, and operational functions make it a key infrastructure for water resource management in California. As a public utility, the dam serves as a vital source of water for irrigation and supply purposes, contributing to the overall water management efforts in the region. With its high hazard potential and state-regulated status, Weber Dam underscores the importance of maintaining and safeguarding critical water infrastructure to ensure the resilience of water resources in the face of changing climate conditions.

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 Weber
Where does the data for Weber 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.
