The Deventer settlement was founded on a river dune on the [[IJssel]]. This river has played a major role for the city over the centuries, because of the trade that this waterway brought with it. In 1241 the city had received the Katentol on long lease from the Elten stift. This toll, which is named after the Katerveer under [[Zwolle]], had to be paid in the Deventer toll house near the Zandpoort, and generated a lot of money in the [[Middle Ages]].

The IJssel has also caused many problems over the centuries, because it often overflowed its banks. Nowadays Deventer has a flood defence, but the Welle ('wal', the name of the street over the quay) is still regularly under water during high water. Dike breaches of the IJssel have created many gullies in and around the city , such as the Douwelerkolk and the Klinkenbeltskolk.

In addition to the IJssel, Deventer has a large number of waters. The [[Schipbeek]] is a brook partly dug on behalf of the city that rises in [[Germany]] and flows into the IJssel near Deventer. In the past, the stream was navigable, so that wood and Bentheimer sandstone could be brought in, among other things. Another waterway that was built for shipping and which flows into the IJssel in Deventer is a branch of the Overijssels canal, through which Deventer was connected to a large system of canals through Overijssel. It was dug in the mid-19th century and opened in 1858.
