Press Release: Valley Water Monitoring New Year's Weekend Flood Watch

December 30, 2022
Flood watch map for December 28, 2022

The National Weather Service is forecasting a strong atmospheric river storm to impact much of Northern California this weekend, with periods of moderate to heavy rain expected Friday night through Saturday evening. The weather service has issued a flood watch from Friday at 10 p.m. through Saturday for much of the Bay Area, including locations in Santa Clara County.

Valley Water is closely monitoring this rain event for potential impacts along waterways in Santa Clara County and our crews are working to ensure our waterways remain clear of debris and blockages.

While our agency does not anticipate flooding along our county’s larger waterways, smaller urban creeks can rise quickly with sudden bursts of rainfall.

Below are essential resources for flood preparedness:

  • Santa Clara County emergency alert system AlertSCC provides up-to-date information on emergencies and disasters in your area.
  • Valley Water’s ALERT (Automated Local Evaluation in Real Time) system provides information on levels of streams and reservoirs and precipitation gauges.
  • Free, filled sandbags are available for residents of Santa Clara County. The sandbag sites are listed HERE.
  • Spills, blockages, or dumping in creeks can be reported by calling Valley Water’s watershed hotline at 408-630-2378.
  • More flood safety tips and resources are available at

The weather service also forecasts another chance of rain next week, providing an opportunity to reduce outdoor water use. Despite the rain, Santa Clara County remains in a drought emergency. We remind the public that under current watering rules, sprinklers should be turned off within 48 hours of rainfall.

Valley Water manages an integrated water resources system that includes the supply of clean, safe water, flood protection and stewardship of streams on behalf of Santa Clara County's 2 million residents. The district effectively manages 10 dams and surface water reservoirs, three water treatment plants, an advanced recycled water purification center, a state-of-the-art water quality laboratory, nearly 285 acres of groundwater recharge ponds and more than 294 miles of streams. We provide wholesale water and groundwater management services to local municipalities and private water retailers who deliver drinking water directly to homes and businesses in Santa Clara County.
