The length of the Scheldt traditionally includes the Westerschelde estuary, which is riverine at low tide [1]. The catchment area includes the complete delta (i.e. including the Oosterschelde), while the discharge is for that near Antwerp. Without the Westerschelde the length would be about 295 km. The source of the Leie may be a few km further upstream than the source of the Scheldt itself.

Peranganjoki [ceb] → Alajoki [sv] (together well over 80 km) → Lake Kiantajärvi (50 km crossing) → Emäjoki [fi; sv] → Iijärvi →Kiehimänjoki (these three 103 km together) → Oulujärvi (75 km course) → Oulujoki (107 km). The entire system above the lake Oulujärvi is also referred to as Hyrynsalmi.
The 204 km Kymi river drains Lake Päijänne, which 120 km further north near Jyväskylä is fed from a network of lakes further north. The sources that feed the lake Koivujärvi are the most distant for Kymi. From there, the shortest route over the so called Rautalampi route [fi] (including lakes Pielavesi, Nilakka, Iisvesi, Kiesimä, Konnevesi, Kynsivesi, and Kuusvesi) and via Saraavesi and Leppävesi to Päijänne is 230 km.
Murdoyoki [ru] (41 km) → Roukkulanjärvi [fi; ru] (27 km) → Omelianjoki [ru] (7 km) → Torosozero [ru]-Leksozero (44 km) → Sula River [ru] (21 km) → Sula lake (7 km) → Lieksanjoki (132 km) → Pielinen Lake (44 km) → Pielisjoki (67 km) → Saimaa. The watershed area is a rough guess.

The furthest headstream of the Arno could be considered the 19th-century, 62 km Canale Maestro della Chiana [fr; it] that drains part of Valdichiana into the Arno about 30 km below its source for a total length of over 270 km. 306 km2 has been subtracted from the HydroBasins area for the endorheic Lake Trasimeno.
