Recovery of 2 Bodies Brings Flood Toll to 8 : Weather: Clinton declares three Virginia counties disaster areas. About $100 million in damage has been caused in more than a week of rains.

The body of a 3-year-old girl snatched from her grandparents by a roiling stream five days ago was pulled Saturday from the swollen Shenandoah River.

Rescuers also found a 64-year-old woman swept into a river by a mudslide, bringing the death toll to eight in more than a week of flooding from days of heavy rain.

Searchers on jet skis found the body of the girl, Alexa Orantes, about 10 miles downstream from the campground where she was washed away in a flash flood on Tuesday, said Janet Clements, a state Department of Emergency Services spokeswoman.

The body of the woman missing since a mudslide pushed her house into the Robinson River on Tuesday was found trapped in rocks 200 yards from her home in Madison County, about 30 miles north of Charlottesville in central Virginia, state police said. Her name was not released.

Despite periods of sunshine, rain returned Saturday to many areas already saturated by more than a week of showers and thunderstorms. A flash flood watch was posted in some areas of the state.

President Clinton on Saturday declared Madison, Rockbridge and Greene counties disaster areas, as well as the towns of Buena Vista and Lexington, making residents eligible for federal assistance.

National Guard helicopters were ferrying in supplies to people cut off by high water and washed-out roads and bridges.

“Our problems in this area are just beginning,” said David Jones, chairman of the board of supervisors in Madison County. “We have just scratched the surface. There are houses missing, roads missing.”

Eighty of the county’s bridges have been destroyed and another 200 are damaged, state officials said. Damage is estimated at $100 million statewide since the flooding began June 22.

“We need bulldozers, backhoes, front-end loaders. And we need people to operate them,” said Mary Beahm of the Madison County Rescue Squad.

Alexa was camping with her grandparents, Roy and Virginia Smith, when water began lapping at their Winnebago’s wheels at the campground in Warren County, north of Madison.

Roy Smith waded several hundred yards with Alexa in his arms and left her on high ground. But the child--apparently fearing her grandfather was in peril--rushed back into the water.

The Smiths watched in horror and screamed for help from a tree they had climbed for safety. When rescuers reached them, they were bruised, battered and up to their necks in water.
