ST. PAUL, Minn. — The Mississippi River is about to get a good scrubbing in the Twin Cities.

Wednesday is riverboat cleanup day along the river, with volunteers to fan out shortly after daylight to pick up the debris that high water has deposited along sandbars. It's the 22nd annual cleanup hosted by the state Department of Natural Resources, with an assist from the Padelford Packet Boat Company, Conservation Corps Minnesota and others.

The garbage that winds up in the Mississippi typically includes tires, barrels, bottles, boat parts, cans and occasionally furniture. Prizes are awarded to volunteers who find the best trash, and an artist will be collecting materials to turn into a sculpture to display at the Minnesota State Fair later this summer.
