Don't Let Litter Trash Your River. Let's all Be River Proud.

It’s officially Spring in Texas! It’s time to celebrate the arrival of many things: Fiesta® San Antonio, celebrations throughout our San Antonio River Basin communities, and the appearance of the stunning wildflowers that make us proud to be Texan. Unfortunately, along with the celebrations come many opportunities for litter to make its way into our local creeks and the San Antonio River.


Litter Goes with the Flow

Litter is a significant pollutant that threatens our watershed and can quickly end up in our river when it rains. During a rainstorm, some rain goes into the ground, where it is soaked up and used by plants and other organisms. However, when the rain hits hardened surfaces like sidewalks, roads, and roofs, it runs right off and gets carried safely down the streets into storm drains. What happens to the plastic bags, single-use water bottles, and dog poop on the roads or sidewalks in the path of the flowing water?

You guessed it. Even if it’s on the land miles away, litter gets carried right into the creeks and streams that feed our river. We call this runoff filled with litter and other pollutants stormwater runoff. River Authority water quality monitoring data sets indicate that stormwater runoff is the most significant contributor to poor water quality in the San Antonio River Basin. As further proof of this problem, the  San Antonio River Basin Report Card‘s grade for public trash has been an F for the past two years, indicating an urgent need to take action.


Besides being stinky and unattractive, stormwater runoff ends up causing many problems for the health of humans and our environment. For example, fish can swallow small pieces of plastic that they mistake for food, and birds can become entangled in plastic nets. People paddling on or swimming in the San Antonio River can potentially get sick if they swallow water containing bacteria like E. Coli.

Take the “Don’t Let Litter Trash Your River” Pledge! 

Hopefully, you now understand that litter is no joke! Luckily, April is Keep America Beautiful® Month and the perfect time to take action as we enjoy Springtime celebrations like the 2022 Mission Reach Flotilla Fiesta

What better way to help preserve the health of our San Antonio River in 2022 than by preventing our litter from escaping our spaces to the storm drains that lead to the rivers and creeks?

Become a River Warrior!

In honor of National Volunteer Month, we invite you to join our dedicated team of River Authority River Warriors.
