The 23rd annual Lake Travis Clean Up kicked off on Sunday and hundreds of volunteers hit the shorelines, diving underwater to remove and recycle items left behind.

Keep Austin Beautiful, Colorado River Alliance and Travis County Parks spearheaded the event to send a clear message -- trash travels.

"Cause things are going -- could be a year old -- and silk covered," Dave Senecal said. "So, you're looking for outlines of beers, bottles and cans, and tennis shoes, things like that.”

He and Tim Kennedy have been working around the lake, recovering items in the most obscure places.

"For someone who has stepped on more than one broken beer bottle in my time, that's one reason why I do it,” Kennedy said.

He says the support on this project is making noticeable changes.

"I think every year we find less and less trash,” he added.

"In past years, we didn't have to move very much and we would fill up a couple of bags," said Senecal. "And now we kind of have to hunt a little bit, so even though people are putting trash in there, we're sort of ahead of them.”

The goal is to also inspire youth to be more proactive, many of who geared up along the shoreline and waterways. Mckinna Pritchard of the FFA is one of them.

"I just think it's important for kids to get involved in their community and help out when they can," she said.

Protecting the waters is more than just keeping it clean, but nurturing the aquatic life.

"Helping the environment helps the ecosystems build up,” another student from the FFA, Aurod Ounsinegad, said. “I've learned that it's always good to give back to the environment that serves you.”

Robert Weiss of Lake Travis Scuba said that over the past year his team of divers have recovered 31 cell phones, 53 pieces of jewelry, 44 masks and goggles, over 1,400 sunglasses and over 200 trash bags in the waters.
