About This Data

Data Source

This data is provided by the U.S. International Boundary and Water Commission (IBWC) and represents real-time monitoring of the Tijuana River at the international boundary.

Update Frequency

Data is updated hourly. This dashboard automatically refreshes every hour to show the latest readings.

What This Means

Higher discharge rates indicate increased sewage flow from the Tijuana River, which can lead to beach closures and water quality advisories in Imperial Beach and South Bay San Diego.

C4CC's solution: operate the PBCILA pumps 24/7 to divert sewage upstream in Mexico, reducing transboundary flow days from 138 to just 30 per year.
