One option is to walk the edge of the waterline and pickup trash from the land. If you’d like to work it from the water itself, canoes and kayaks are also available (loaned by our local schools/clubs).
Trash bags and grabbers are provided at several staging areas along the river. The whole event is organized by Keep Austin Beautiful with help from the Sierra Club and many others.
Full details and registration can be found here.
It’s a great way to meet like-minded new folks and know that you are doing some true good for our water-loving lifestyle in Austin. There’s much more to the overall event that you can read about on the KAB link. See you there!
