Waaltje

The Waaltje (common name; Dutch for Little Waal) is a dammed river in the western Netherlands, southeast of Rotterdam. Historically it used to be the western end of the Waal river, hence its official name continues to be Waal, although the intermediate Waal sections, Boven Merwede, Beneden Merwede, and a subsection of the Noord, have long changed their names.

The Waaltje marks the border between the Zwijndrechtse Waard, formerly a separate island, and the historic Island of IJsselmonde. Since the damming of this Waal section, IJsselmonde also encompasses the Zwijndrechtse Waard (see map to the right).

The Waaltje runs from Hendrik-Ido-Ambacht, along Oostendam, through Rijsoord, and along Barendrecht to Heerjansdam. In Heerjansdam it now connects to the Oude Maas through a pumping station. In 1332 William I, Count of Hainaut had the Waal dammed at Oostendam.

In Hendrik-Ido-Ambacht the Waaltje connected to the Noord through the old port of Ambacht. Now the Waaltje ends just southwest of the Damweg. Recently, the old port of Ambacht has also been dammed on the northeast side, transforming it into another enclosed section of the old Waal.

The Waaltje is crossed by a highway, the A16, the railway between Rotterdam and Dordrecht, the HSL and the Betuweroute. The A15 runs between the A16 and the Noord to the north of the Waaltje.

The Waaltje is managed by the water board Hollandse Delta. Its waters are on the clear end. It is used for boating, amateur fishing, diving, swimming and skating.

Along the eastern bank of the Waaltje in Heerjansdam, between the clubhouse of the business association and the restaurant, volunteers from among others the environmental association Heerjansdam created an educational nature trail named Waalpad. Other walking trails along the Waaltje can be found in Hendrik-Ido-Ambacht, along the Kerkstraat and between Oordenweg and Jaapgpad. Nature development Wevershoek in Barendrecht also offers opportunities to walk along the Waaltje.
