Update 1/3/2024 - 10:30 A.M.
The SFCJPA is aware that the rain gages are not displaying updated rainfall data on the Contrail website. The gages are functioning, and data can be viewed on Valley Water's website at: https://alert.valleywater.org/?p=map
We are working to correct this display issue.
***
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 that informs 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
