Here is the Santa Ana Watershed Project Authority's page about their weather modification program: https://sawpa.gov/santa-ana-river-watershed-weather-modification/
The program started on November 15, 2023 and will last through April 2027.
Unfortunately, it looks like they update the schedule retroactively, so we don't know what days they did cloud seed, just what days they did it.
Audra Morgan of Eye of the Storm did an investigative journalism story on her podcast: https://rumble.com/v4cikou-eye-of-the-storm-s2-e46-021024-riding-solo.html
NOTE: THIS PROGRAM IS CLOUD SEEDING AT LOW ALTITUDES AND IS NOT PART OF GEOENGINEERING OR CHEMTRAILS BUT IS PART OF THE CALIFORNIA WATERSHED DROUGHT MITIGATION PROJECT
