Seven members of the Patoka River National Wildlife Refuge took to the river on Thursday to hunt for some trash.
This is something they have been doing once a year so they say it's not as bad as it has been.
Heath Hamilton, a wildlife refuge specialist with the Patoka River National Wildlife Refuge, says they used to find big household items like refrigerators dumped in the river.
"There's kind of been a history of trash dumping," says Hamilton. "It's just been a place where people who maybe don't appreciate nature or wildlife or wild places as much as you and I do take their trash and their heavy trash and dump it."
Hamilton says they've removed the bulk of the trash over the years but they still do an annual river sweep just for the visitors.
"When they come here we want them to leave with a nice impression of the refuge," says Hamilton. "We want them to see a nice clean stream, a nice healthy river and a nice healthy forest around that river so that's why we're here to pick up trash today."
