Surf, sand, and sun just another typical summer day on the shores of Lake Michigan.

"We've been swimming, skate boarding, hanging out in the sun," Steve Utter of Jackson said.

But unfortunately for beach goers, they've also had to hang out with some unwanted guests.

"I found some bags, ribbons, miscellaneous debris," Utter said.

"We found a lot of balloons and ribbons and straws and bottle caps," Patty Murphy of Haslett said.

Garbage is washing ashore. The coast guard said since Monday they've fielded calls of trash from Ludington all the way down to Holland.

The latest report of garbage came Thursday afternoon from the Stoney Lake area.

"It's disappointing," Utter said. "I wish people would clean up their garbage."

For the most part the garbage has been cleaned up, but the Coast Guard said they don't know where it's coming from and they're still investigating.

"It makes you wonder is it coming out from the river?" Ann Davis of Grand Haven wondered. "Are people dumping it off their boats, are people being negligent at the beach?"

The coast guard said they're working with local police departments, the Department of Environmental Quality and the Army Corps of Engineers to get to the bottom of this.

Michiganders say their saddened by this news, but doing their part.

"I pulled some thins out and put it on the shore," Utter said.

So everyone can enjoy the water this summer.
