WILKES-BARRE, Pa., (Reuters) – The Susquehanna River, swollen by rainfall from the remnants of Tropical Storm Lee, reached record levels in Pennsylvania yesterday and submerged some towns amid worry that flood waters had been turned toxic by swamped sewage processing plants.
Rainfall ended in the region from the powerful weather system that earlier drenched the U.S. Gulf Coast. But rising rivers and stressed dams and levees presented a stern challenge to Pennsylvania as well as Virginia and Maryland, states socked by flooding in late August after Hurricane Irene.
One Pennsylvania college town, Bloomsburg, was under water and closed to all but emergency workers.
The Susquehanna reached a record high of 42.6 feet (13 meters) in hard-hit Wilkes-Barre early yesterday but the levee system held in the northeastern Pennsylvania city, meteorologists said. The river topped the 40.9-foot (12.5 meters) level in flooding caused by Hurricane Agnes in 1972.
By later yesterday, Susquehanna had receded a bit to 41.4 feet (12.6 meters).
A levee system protected Wilkes-Barre but remained under heavy pressure and had sprung a few small leaks, Luzerne County engineer Jim Brozina said at a news conference.
“It is under extreme stress right now. I mean, we are well beyond our design for this system,” Brozina said. “Every hour is a benefit to us as that river starts to recede.”
Pennsylvania Governor Tom Corbett earlier told residents to steer clear of the river waters, which were turned into a toxic mess after flooding washed out 10 sewage processing plants.
Governor Bob McDonnell yesterday declared a state of emergency in Virginia due to the flooding.
At least five people earlier were killed in the flooding in Pennsylvania and Virginia and more than 130,000 people were evacuated on Thursday in Pennsylvania, New York and Maryland.
“This is a record flood in many areas, and people should expect the unexpected,” said Joel Myers of Accuweather.com, who warned of potential sinkholes, flash floods, dams failing and bridges collapsing.
The most severely flooded were small towns without dikes along the Susquehanna River about 50 miles (80 km) north and south of Wilkes-Barre.
Dikes at Wilkes-Barre and Kingston, on the opposite side of the Susquehanna, were raised as much as 12 feet (3.7 meters) and fortified following the devastating flood caused by Hurricane Agnes.
