TROY — The city said late Sunday afternoon that a massive water main break has been isolated, but that water will appear discolored into Monday.

However, there has been no boil water advisory issued.

Mayor Patrick Madden had declared a state of emergency in the city after a water main break in Lansingburgh sent water rushing down 124th street, causing major flooding on Second Avenue.

As a result, residents were being asked Sunday to curtail their water usage and the city has opened warming stations at the Department of Public Utilities, 25 Water Plant Rd. and the Lansingburgh Boys & Girls Club, 501 4th Ave.

Troy city spokesman John Salka said residents are being asked to not run dishwashers or washing machines, and otherwise try to cut down on their water usage after a main broke at the intersection of New Turnpike Road and Northern Drive Sunday morning.

It's unknown Sunday night if water conservation should be continued now that the break is being fixed.

The break happened around 9 a.m. - sending water hundreds of feet into the air, said resident Lynn Delamater, who witnessed it happen from her home on New Turnpike. "I said, 'The whole road blew up!'" Delamater said she told 911 operators.

The break sent water rushing down Northern and 124th streets, carrying road debris with it and flooding basements. Residents on Third Avenue created a makeshift berm with old doors and tires to keep the water from running down their street.

Water had subsided as of Sunday afternoon, but not in the worst affected area of Second Avenue between 124th and 125th streets around Price Chopper, which had several feet of standing water.

The break left a huge crater, with police cautioning those to watch where they walked for fear the ground around it would open up. Madden and Rensselaer County Executive Kathy Jimino were getting a tour of the damage Sunday afternoon.

The state Division of Homeland Security and Emergency Services Office of Emergency Management Sunday put out a news release saying it was directed by Gov. Andrew Cuomo to respond to the water main break.

The release said Rensselaer County has requested the state to provide a 5,500 gallon water tanker through the State's NY Responds incident management system. This will provide potable water to affected residents.
