Would you believe a lot of people aren’t aware that a lot of our storm drains empty out directly into our creeks?!

Trash, oil, grass clippings, dog poo bags…you name it, can end up washing into these critical waterways.

If you are interested in marking storm drains in your community, you can reach out to the city, or we can help you organize a neighborhood storm-drain marking event for one of your favorite south Austin streams/creeks!

Hey friends - pay attention. We only have 24 hours left to make our voices heard. We don’t need another highway expansion.

Austin doesn’t need anymore pavement, anymore impervious coverage, toll lanes, indiscriminate destruction of our watersheds, creeks, caves and aquifer. We don’t need it.

We don’t need more traffic snarls caused by more construction on MOPAC. That ten minutes it will save you on your drive when it’s done in 5-10 years is going to cost hours before it’s finished while you sit in traffic. It’s a zero sum game. Also, if you want to save that ten minutes on your drive, it will cost you because why? More toll lanes. Please go check out our friends at Better MOPAC Coalition if you haven’t already. They can give you all the details on why so many of us oppose this and how to submit your comments to CTRMA before the deadline tomorrow.

Celebrate National Volunteer Week April 19-25 by helping scientists and researchers understand and protect nature.
Join the City Nature Challenge 2026: Austin on April 24-27, 2026.
Join here and upload the iNaturalist app. https://www.inaturalist.org/projects/city-nature-challenge-2026-austin

Join the City Nature Challenge, a worldwide movement to document nature and help fight biodiversity loss! Every observation you make of WILD nature in the Greater Austin Area is a data point that helps scientists and researchers understand and protect nature for all of us.

How to participate:�From April 24 - April 27, 2026, get outside and take photos or record sounds of nature where you live. Look for WILD plants, animals, fungi, etc. (Wild means it was not put there by people and is not being taken care of by people.) Take a close look at the plants around you. Are there any insects or spiders on them? How many different types of birds can you find in your local park? Put on your nature eyes and see the Greater Austin Area in a whole new way!

From April 24-27th, upload your observations to the iNaturalist app and help identify what others have seen.

By participating in the City Nature Challenge, we can connect with nature, connect with each other, and connect with cities all over the world!

The City Nature Challenge is organized globally by the California Academy of Sciences and the Natural History Museum of Las Angeles County. The Greater Austin Area City Nature Challenge is put on by Austin Parks and Recreation Department, Texas Parks and Wildlife, Texas Master Naturalists, the Nature Conservancy, the Audubon Society, and many others.
