NEW ORLEANS (AP) — The Louisiana National Guard says they’ve wrapped up rescue operations in Plaquemines Parish, which was hit hard by flooding as Isaac stormed through.

National Guard spokesman Capt. Lance Cagnolatti says guardsmen are confident they’ve swept the thinly populated area and no one is still there.

Guardsmen rescued between 60 and 70 people in the area. None had any serious injuries, though an elderly woman who required dialysis was taken to a hospital. Cagnolatti says the search turned up no bodies in the floodwater.

Flooding has plagued the area since Isaac sloshed ashore Tuesday evening as a Category 1 hurricane. Officials plan to intentionally breach a levee in the area to alleviate pressure on it.
