Isaac could mean some relief to low Miss. River

Rain from the remnants of Hurricane Isaac could help the drought-stricken Mississippi River, but experts say it's not enough for long-term relief.

The U.S. Army Corps of Engineers is trying to keep barge traffic flowing on the vital shipping channel that is at its lowest level in years.

Marty Pope, a hydrologist for the National Weather Service in Jackson, Miss., says Isaac dumped rain on areas that feed the lower Mississippi.

But he says it is too little for a sustained rise in water level.

Corps spokesman Kavanaugh Breazeale says the river could rise two feet at Vicksburg, Miss., over the coming weeks, but it'll go down again without more rain.
