Rio Hondo Watershed

The Rio Hondo Watershed boasts some of the most geologically, geographically, and culturally diverse communities in LA County.

Starting at San Gabriel Mountains, this watershed drains to the Rio Hondo, then to the LA River, and finally into the Pacific Ocean. The Rio Hondo watershed also includes the Arcadia Wash, Rubio Wash, Eaton Wash, and Santa Anita Wash. Ten of the cities within the watershed have a primary language other than English, including Spanish, Mandarin, and Cantonese. 

Learning from my dad, who is a fellow watershed coordinator, inspired me to always care about preserving our water and natural world. He is more of a scientist, and I am more of a people person. We make a great team. I think the best approach is to meet people where they are and just listen. It could be at a neighborhood council meeting or my little table at the Alhambra Farmers Market. I’m kind of a dork about water capture, and it turns out people get excited when they learn what impact we can make together.

From the Community

  • Vincent Lugo Park (LA County)
  • Stormwater Capture Project in East LA (LA County Public Works)
  • Like other watersheds in the LA County Basin, this land is indigenous to the Gabrielino and Tongva peoples and is home to many historic villages.  
  • “We have a lot of good fortune here in our built world, but it would be really, really great if we could do the same for our natural world too.”
