The IJssel as a Rhine distributary

From the moment the connection between the Rhine and IJssel was dug, the Rhine became the largest contributor to the flow of the IJssel, although only a relatively small amount of the total Rhine flow makes its way into the IJssel system. Various tributaries can sometimes add a considerable volume of water to the total flow of the IJssel, such as the Berkel

The modern-day names of the delta branches are, west to east, Keteldiep, Kattendiep, Noorddiep, Ganzendiep and Goot. Of these, the Keteldiep and Kattendiep channels are the main navigational arteries; the Noorddiep has been closed off at both sides. Another branch, De Garste, had already completely silted up by the middle of the nineteenth century. Until the beginning of the twentieth century, the Ganzendiep branch up to the Goot fork was known as IJssel proper. due to it being the historical main channel, with the present-day main channel being called Regtediep or Rechterdiep until well into the twentieth century

The IJssel, although now technically "merely" a Rhine branch, has retained most of the character of a distinct river in its own right, in no small part due to the fact that it has its own tributaries and, in river Oude IJssel, even a former headstream.
