Emergencies and alerts

If this is a water emergency please call
1-866-403-2683 any time.

Water emergencies may include: No water service, broken hydrants, main breaks, flooding in the street or other EBMUD water-related emergencies. Temporary water outages and traffic delays may occur when crews repair or replace a pipe or other infrastructure.

When repairs are made in your neighborhood, you may want to flush your home faucets. Once water service is restored, turn on your front hose bib – the outdoor faucet at the front of the house – until the water runs clear. Also run cold water from the faucets inside your home for 1-3 minutes until clear. Read more about what to do when EBMUD crews are in your neighborhood


Camanche Dam and Spillway are safe

Heavy rains continue to fill reservoirs

EBMUD has an active, comprehensive dam safety program to protect lives and property. The District monitors Camanche Dam regularly for evidence of seepage, ground movement, maintenance needs and assesses the integrity of the spillway and related facilities. Camanche Dam is operated by EBMUD and overseen by both the California Division of Safety of Dams and the Federal Energy Regulatory commission.

Like all EBMUD dams, Camanche is regularly monitored using state of the art geotechnical and survey instrumentation and comprehensively inspected (monthly by EBMUD and annually by EBMUD and regulators.) EBMUD does annual emergency response exercises together with affected agencies such as PG&E, local law enforcement and fire. The last exercise was in December 2016.

The safety of dams is continually reevaluated as experts advance our understanding of geotechnical, structural and earthquake engineering. Based on the findings of dam safety studies, over the past several decades EBMUD has proactively made numerous capital improvements to its dams to ensure their ongoing safety.

For more information call 1-866-403-2683.

EBMUD managing February storms and rainfall

Continued heavy rains fill East Bay reservoirs and increase creek flows above and below local reservoirs.

Northern California continues to experience significant rainfall. After years of historic drought, East Bay Municipal Utility District has a healthy water supply, with all East Bay reservoirs and Pardee Reservoir, the largest reservoir that serves the East Bay, full.

Through February 8, the rainfall year-to-date total in our Mokelumne River watershed in the Sierra foothills is 57 inches, which is wetter than 1983, the wettest year on record. The East Bay received 4.5 inches of rainfall, bringing the monthly total to 337% of average. EBMUD’s local reservoirs – San Pablo, Upper San Leandro, Briones, Lake Chabot, and Lafayette – are all full, with more rain in the forecast. With full reservoirs and continued rain, many reservoirs in California are spilling.  

EBMUD makes controlled releases from its reservoirs during drier periods between storms. Releases are an essential step in managing reservoir capacity to create space for anticipated precipitation. While releases are planned and regulated for specific flows, spilling from reservoirs takes place only when reservoirs are completely full. There have been no planned releases from reservoirs during rain events or spilling.

With recent storms bringing in more than one inch of rain each day February 6 and 7, Upper San Leandro, San Pablo and Lake Chabot Reservoirs reached maximum capacity and are spilling. 

Forecasts call for 1.3 inches of precipitation in the East Bay through Friday, February 10, followed by a dry period through Wednesday, February 15. More rain is forecast for February 16 - 23.

Once flows in San Pablo Creek and San Leandro Creek recede, EBMUD will release water from reservoirs to make room for future storms.

EBMUD is working with Contra Costa and Alameda counties to provide continued information to property owners along local creeks. Resource information for property owners along creeks are available:  


  • Road closures: Alameda County Public Works www.acpwa.org/storm-closures-information/
  • Flood control: Alameda County Flood Control and Water Conservation District
  • Flood emergencies: dial 911
  • Report flooding of major creeks: 510-670-5500
  • Flood preparation info www.acfloodcontrol.org/flood-risk-and-preparation/




EBMUD continues to monitor the landslide area for movement. In preparation for the rainy season, tarps were placed at the site to reduce water flowing into the landslide area. Anyone owning property in this area is responsible for and encouraged to take necessary steps to monitor their property. Read more
