The Hollandse IJssel ("Holland IJssel", as opposed to the 'regular' or GelderlandIJssel) is a branch of the Rhinedelta that flows westward from Nieuwegein on riverLek through IJsselstein, Gouda and Capelle aan den IJssel to Krimpen aan den IJssel, where it ends in the Nieuwe Maas. Another branch called Enge IJssel ("Narrow IJssel") flows southwest from Nieuwegein. The name IJssel is thought to derive from the Germanici sala, meaning "dark water". Originally, the Hollandse IJssel forked off from river Lek at Nieuwegein, but the connection was cut off with the Hollandse IJssel nowadays only draining the surrounding pastures.
