In its ninth year, the June 24 College Creek cleanup yielded nearly 1,000 pounds of trash and debris from the stretch of College Creek that winds through campus. A group of 31 volunteers spent a combined 43 hours bagging discarded items and pulling large pieces -- including a tractor tire, bike, safety barricade, fence posts, foam insulation, lengths of pipe and lots of plastic bags -- from the banks and bed of the waterway. The annual cleanup is part of the Live Green program and Keep Iowa State Beautiful initiative.
