The teens were holding onto the ice shelf when emergency crews arrived, according to the Greenwich Professional Firefighters Facebook page.
The teens were transported to the Stamford Hospital emergency room, where they were treated and released to their parents, according to Greenwich police spokesman Lt. Kraig Gray.
"Thankfully, the two teens were not seriously injured," the Greenwich Police Department said via Twitter @GreenwichCTPD. "Two teens engaged in risky behavior walking out onto thin ice in Riverside. They fell through and had to be rescued."
Engines 5, 2, 1, Truck 1 and Car 3 from the Greenwich Fire Department responded to the scene.
