The other third of the water flows through the Pannerdens Kanaal and redistributes in the IJssel and Nederrijn. The IJssel branch carries one ninth of the water flow of the Rhine north into the IJsselmeer (a former bay), while the Nederrijn carries approximately two ninths of the flow west along a route parallel to the Waal. However, at Wijk bij Duurstede, the Nederrijn changes its name and becomes the Lek. It flows farther west, to rejoin the Noord River into the Nieuwe Maas and to the North Sea.
If two thirds of the Rhine flows through the Maas, where doe the other one third flow through? The Rhine redistributes into the Ijssel and what other body? What does the Nederrikn's name change into? Where does the Lek join?  If two thirds of the Rhine flows through Waal, where does the other third flow through? Other than the Ijssel, where does the water from the Pannerdens Kanaal redsitrubute? How much of the Rhine flow does Ijssel carry? What does the Nederrijn change it's name to? Where does the Nederrijn change it's name?
