The Súd Ie is a waterway located in the province of Fryslân in the northern Netherlands, situated within a polder landscape that connects to broader aquatic systems including the Lauwersmeer and, ultimately, the Wadden Sea. This water body is part of an ecologically significant network of ditches, channels, and natural areas managed through a collaborative effort involving Wetterskip Fryslân, the Municipality of Noardeast-Fryslân, It Fryske Gea, and the Province of Fryslân. In recent years, the Súd Ie has been the focus of active ecological restoration, including the construction of fish passages and the creation of nature-friendly banks, making it an increasingly viable destination for anglers interested in targeting species characteristic of the Dutch polder and coastal wetland environment.
