Catchment area and length

Until the German -Dutch border the catchment area of ​​360.88 km ² Issel is large, and until then the German section of the river is about 55 km long. The catchment area extending beyond the limit subsequent Oude IJssel has to lie in Doesburg mouth of the IJssel 847.12 km ² in area, and the Dutch part of the river is 26.5 km long. From the Issel source to the mouth of the Oude IJssel the catchment area is 1208 km ² in total, and the river is 81.5 km long completely. The total flow distance Issel and, from Doesburg, the IJssel to the confluence with the Ketelmeer is 178 km long ( other reportedly 177.8 km ), and this river has a 4269.645 km ² large catchment area.

The above-ground catchment area of ​​the Issel is not always the hydrologically effective because the groundwater flow is directed partially transverse to the Issel to the Rhine in the west area. Thus, the river loses water flowing down.


In Germany the Drevenacker Landwehr, the Small Issel and the Wolf strand Issel flow to. In the Netherlands these are the Aa - strand ( lower reaches of the Bocholt Aa ) and Sloerstrank, Akkermansbeek, Bielheimerbeek, Waalse Water and Hoge Leiding. Of these, the most important tributary is the Bocholt Aa flows Issel in the Netherlands Ulft, community Oude IJsselstreek than Aa strand. This has a larger catchment area than the Issel ( 536 km ² compared with 360.88 km ² ) and executes significantly more water than these (6.0 m³ / s compared with 3.0 m / s at the muzzle point). Nevertheless, the flow downstream will still be called Oude IJssel.

The Issel / Oude IJssel flows further to the north west, and marks the course of the Issel fracture, a former stream channel of the Rhine and the Lippe.
