VICKSBURG, Miss. (AP) — U.S. Army Corps of Engineers officials say they plan to start dredging the Port of Vicksburg Monday to help river traffic deal with low water in the Mississippi River.

The Post reports that Tropical Storm Isaac provided a bit of relief from ongoing drought, but the Mississippi River is slipping back toward negative stages. A drought across much of the nation has led to low water levels in the Mississippi this year and has caused problems for river businesses.

Marty Pope, a senior hydrologist with the National Weather Service office in Jackson, said river levels would oscillate in the coming weeks but remain low.

Pope said rain in the upper reaches of the Mississippi River valley has helped conditions for now.
