NIAGARA FALLS, N.Y. (AP) The city of Niagara Falls continues to clean up damage from last week's severe storms that brought down numerous trees and knocked out the municipal sewage treatment system.

The Niagara Gazette reports ( ) that millions of gallons of untreated sewage continue to flow into the Niagara River as the city's Water Board scrambles to install temporary bypass pumps at the main processing station.

Fierce storms Friday night and Saturday flooded the city's wastewater treatment plant, overwhelming the facility's pumps.

Mayor Paul Dyster says the city will hire an outside contractor to help the Department of Public Works with removing the many trees damaged by the storms.

The National Weather Service says a tornado touched down briefly Friday night along the Lake Ontario shore in Greece, a Rochester suburb.
