The Dredge Goetz is dredging the navigation channel below Lock and Dam 15. Hydraulic dredging operations began Sunday and were expected to end Friday. However, the dredging may be over as early as Tuesday.

"It's been a while since they've dredged there and it's considered routine scheduled maintenance dredging, not due to the low water or the drought," said Ron Fournier, spokesman for the U.S. Army Corps of Engineers. "The dredging is done to ensure a minimum 9-foot navigation channel for commercial tows. They should be finishing up tonight and packing up the gear tomorrow to head out of town."
