LAMBERTVILLE - Several days of below-freezing temperatures have led to ice forming on many of New Jersey's waterways, and the Delaware River is no exception.

The build-up of ice is now creating a threat of flooding along the river banks near Trenton and Lambertville.

A Coast Guard cutter came through to get water flowing.

The build-up is at least three miles long. Rain predicted for the weekend could cause additional problems.

Residents say they haven't seen an ice build up like this in decades.
