The Lek is a river in the western Netherlands of some 60 km 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 river Rhine. The name "Lek" is derived either from the Middle Dutch words "lake" and "leek", meaning "watercourse"
