NEW ORLEANS (AP) - Louisiana Gov. Bobby Jindal says officials expect to have 70 percent of the water out of an area of Plaquemines Parish that flooded after being hit by Isaac.

Jindal credits the development to a change in wind direction and the intentional breach of a levee there Thursday.

More than 100 people had to be rescued from flooding in the area south of New Orleans after Isaac made landfall Tuesday evening.

Jindal also said Friday that Mississippi's work to alleviate pressure on a dam on Lake Tangipahoa appeared to be working. Fears that the dam could fail prompted evacuations in Louisiana on Thursday.
