Ketelmeer

The Ketelmeer is the tongue of the IJsselmeer into which the River IJssel drains, it is located among the polders Noordoostpolder and Oostelijk Flevoland and connects the river IJssel to the IJsselmeer. It is one of the bordering lakes, a non-stop frame of water which separate Flevoland from the Noordostpolder and the historical lands of the provinces of Gelderland and Utrecht.

The Ketelmeer covers a place of 3500 hectares, most of that is inside the province of Flevoland, but the river delta of the IJssel is in province of Overijssel. It turned into carved out from the Zuiderzee by means of the development of the polders of Noordoostpolder and Flevoland, among which it lies. It is through Ketelmeer that the IJsselmeer connects to the Zwarte Meer and the Veluwemeer, the strip of water which separates Flevoland from the coast of the mainland. The Ketelmeer includes the IJsseloog, a kilometer diameter round pit in an synthetic island, built to comprise the toxic sludge dredged from the mattress of the Ketelmeer.
