The Oude IJssel is a scenic river stretching approximately 82 kilometers (51 miles) through both Germany and the Netherlands, originating near Raesfeld in Westphalia, Germany, at an elevation of about 55.5 meters, and flowing westward before joining the IJssel near Doesburg in the Gelderland province of the Netherlands at an elevation of roughly 5 meters. With a drainage basin of 1,214 square kilometers and an average discharge of 10.5 cubic meters per second measured at Doesburg, the Oude IJssel carries a rich history as the former upper course of the IJssel itself — a connection that was altered, possibly as far back as the Roman era, when the link with the Rhine was established. The river passes through a variety of landscapes across its course, including the industrially historic area of Ulft with its DRU Industriepark, offering anglers a blend of natural riverine environments and culturally significant surroundings. As a right tributary of the IJssel, the Oude IJssel forms part of the broader Rhine–Meuse–Scheldt Delta system, giving it hydrological characteristics influenced by the larger Rhine basin.
