The Neder-Rijn (also written Nederrijn) is a powerful, navigable river stretching approximately 50 kilometers (31 miles) through the central Netherlands, flowing westward from its source at the Pannerdens Kanaal near Huissen in Gelderland to Wijk bij Duurstede in Utrecht, where it transitions into the Lek. The city of Arnhem sits on the river's right (north) bank, and the IJssel branches off just downstream of the city. As part of the greater Rhine–Meuse–Scheldt delta system, the Neder-Rijn is a major river fishery holding a diverse range of species, making it one of the most productive big-river fishing destinations in the Netherlands. The river is a public water accessible to anglers holding a valid VISpas, and it supports both daytime and night fishing on designated sections.
