Lek

The Lek ( Dutch pronunciation: [lɛk]) is a river in the western Netherlands of some 60 km (37 mi) in length. It is the continuation of the Nederrijn after the Kromme Rijn branches off at the town of Wijk bij Duurstede. The main westbound waterway is hereafter called the Lek River. The Nederrijn is, itself, a distributary branch of the river Rhine.

Portions of the river form the boundary between the provinces of Utrecht and Gelderland, and between Utrecht and South Holland.
