Thousands of people hit Lake Travis this Labor Day weekend -- bringing their trash along with them.

As the holiday weekend comes to a close, volunteers will be out cleaning it up, but for many divers, it's something they encounter all year long.

Lake Travis Scuba owner Robert Weiss is on the lake several times a week and shares the water with crowds of people on party barges every weekend.

"They come and go all day long," he said. "They could be groups from businesses, church organizations, fraternities [or] sororities."

While he knows most of the crews and captains, a majority of his time is spent under water with other divers.

"We like diving. We enjoy diving, we enjoy our lake. We've got the best lake in Texas to dive in," he said.

They hope to keep it that way, but the amount of trash they find is excessive.
