IJsselmeer
The IJsselmeer, or Lake IJssel, will be a fitting arena for the World Championships. With its 1,100 km2 it is the fifth largest lake in Western Europe (have a look at this current situation). The shallow lake in the central Netherlands — bordering the provinces of North Holland, Flevoland and Friesland — has an average depth of 5 to 6 m. It is named after the river IJssel that drains into it via a smaller lake, the Ketelmeer.
The lake was created as recent as 1932 when an inland sea, the Zuiderzee (meaning “southern sea” in Dutch as opposed to the North Sea), was closed by a 32 km dam, the Afsluitdijk. This was part of a major hydrologic engineering project known as the the Zuiderzee Works, that years later led to the reclaiming of land from the IJsselmeer, thereby diminishing the size of the lake considerably. The original Zuiderzee covered 5,000 km2! (As shown in the historical image above, drawn by Dutch cartographer Johannes Janssonius in 1658).
In 1975 the IJsselmeer was further split in two by the completion of the Houtribdijk, now also called Markerwaarddijk, which runs from Enkhuizen southeast to Lelystad. This former southern part of the IJsselmeer is now the hydrologically separate Markermeer.
The IJsselmeer functions as a major fresh water reserve, serving as a source for agriculture and drinking water. It also offers plenty of opportunities for various recreational activities, obviously sailing being one of them.
The province of Flevoland was created in 1986 from the polders reclaimed from the IJsselmeer. |
