The Volkerak is a body of water in the Netherlands. It is part of the Rhine–Meuse–Scheldt delta, and is situated between the island Goeree-Overflakkee to the north-west and the Dutch mainland to the south and east. The western part of the Volkerak is also called Krammer. Tributaries of the Volkerak are the Dintel and Steenbergse Vliet.
Before 1987, it was a tidal river open to the North Sea, but it was closed off as part of the Delta Works; it is now a fresh water lake.
The Hollands Diep (pre-1947 spelling: Hollandsch Diep) is a river in the Netherlands, and an estuary of the Rhine and Meuse rivers. Through the Scheldt–Rhine Canal it connects to the Scheldt river and Antwerp.
The Bergse Maas river and the Nieuwe Merwede river join near Lage Zwaluwe to form the Hollands Diep. The Dordtsche Kil connects to it near Moerdijk. Near Numansdorp it splits into the Haringvliet and the Volkerak.
Goeree-Overflakkee (Dutch pronunciation: [ɣuˌreː ˈoːvərflɑˌkeː]) is a delta island and an administrative municipality in the province of South Holland, Netherlands, with a population of 50,589. It is the largest island by land area in the Netherlands after the man-made Flevopolder.
Goeree-Overflakkee is separated from the islands of Voorne-Putten and Hoeksche Waard by the Haringvliet, from the mainland of North Brabant by the Volkerak, and from Schouwen-Duiveland by Lake Grevelingen.
Willemstad is a city in the Dutch province of North Brabant. It is located in the municipality of Moerdijk. Its population as of 2021 was 2,490.
Willemstad is a small historical town with well preserved fortifications. It lies on the Hollands Diep, close to the Haringvliet and Volkerak. It received city rights in 1585. The Reformed Church was built in 1607 as the first new Protestant church building in the Netherlands (see: the Reformation and its influence on church architecture).
The Scheldt–Rhine Canal (Schelde-Rijnkanaal) in Belgium and the Netherlands connects Antwerp with the Volkerak, and thereby the Scheldt with the Rhine.
The Haringvliet is a large inlet of the North Sea, in the province of South Holland in the Netherlands. It is an important estuary of the Rhine-Meuse delta.
Near Numansdorp, the Hollands Diep splits into the Haringvliet and the Volkerak estuaries. It is closed off near Goedereede from the North Sea by the Haringvlietdam, which provides a road connection between the island of Voorne to the north and the island of Goeree-Overflakkee to the south. The dam with its sluices was built as part of the Delta Works sea barrier protection works.
