Update 11/12/2024 2:30pm

Stream flow gages at Bear Creek and Los Trancos Creek are being repaired or replaced. Until that is complete, these gages will not be reporting information. When they are back online, they will report flows greater than 100cfs.

We are working to correct these issues.

Additional information is available at the following websites:

Rain gages are functioning, and data can be viewed on Valley Water's website at: https://alert.valleywater.org/?p=map

***

Using rainfall gages in the upper watershed and creek flow gages far upstream of the urbanized floodplain areas, the SFCJPA collects real time rainfall and streamflow data from the upper watershed and uses that to inform local first responders.

For data visualization of real-time rainfall and creek conditions, please visit the City of Palo Alto’s website at: Creek Monitor & Camera – City of Palo Alto, CA

Current and Predicted Weather and Stream Flows

The National Oceanic and Atmospheric Administration (NOAA) California and Nevada River Monitoring System has a page for the San Francisquito Creek.

This page documents past, and projects future flow conditions based on NOAA’s rainfall gauges and models.
