Marquisate Quay (1980-1983)

The Markiezaatkade is a four kilometer long auxiliary dam that runs from Zuid-Beveland (east of the Kreekrak locks) to the Molenplaat, just outside Bergen op Zoom. The Markiezaatkade is built to facilitate the construction of the Oesterdam and to prevent the water currents in the Scheldt-Rhine canal from becoming too strong.

Construction of the dam begins in January 1981 and is completed in March 1983. Behind the dam a lake is created, the Markiezaatmeer. The water in this lake turns into fresh water after a few years and develops into one of the largest wetlands in the Netherlands. Every year hundreds of thousands of migratory birds land there.

This fresh water reservoir plays a major role in the water management of the area. This supply can be used in dry periods, while, during wet periods, the lake also serves as an overflow for surplus surface water from the western part of Noord-Brabant.


Fresh and salt

To prevent salt water from entering the lake, both the Kreekrak locks and the Krammersluizen in the Philipsdam are equipped with an ingenious system that separates salt and fresh water. If, by chance,  some salt water ends up in the fresh water of the Markiezaatmeer, it is pumped away through a drainage canal and the Bath drainage sluice.
