Flevolands, Zuiderzee Works

Eastern Flevoland (Oostelijk Flevoland or Oost-Flevoland) and Southern Flevoland (Zuidelijk Flevoland or Zuid-Flevoland), unlike the Noordoostpolder, have peripheral lakes between them and the mainland: the Veluwemeer and Gooimeer respectively, making them, together, the world's largest artificial island.

They are two separate polders that have a joint hydrological infrastructure, with a dividing dike in the middle, the Knardijk, that will keep one polder safe should the other be flooded. The two main drainage canals that traverse the dike can be closed by weirs in such an event. The pumping stations are the Wortman (diesel powered) at Lelystad-Haven, the Lovink near Harderwijk on the mainland and the Colijn (both electrically powered) along the northern dike beside the Ketelmeer.

A new element in the design of Eastern Flevoland is the larger city Lelystad (1966), named after Cornelis Lely, the man who had played a crucial role in designing and realising the Zuiderzee Works. Other more conventional settlements already existed by then; Dronten, the major local town, was founded in 1962, followed by two smaller satellite villages, Swifterbant and Biddinghuizen, in 1963. These three were incorporated in the new municipality of Dronten on January 1, 1972.

Southern Flevoland has only one pumping station, the diesel powered De Blocq van Kuffeler. Because of the hydrological union of the two Flevolands it simply joins the other three in maintaining the water-level of both polders. Almere relieves the housing shortage and increasing overcrowding on the old land. Its name is derived from the early medieval name for Lacus Flevo. Almere was to be divided into 3 major settlements initially; the first, Almere-Haven (1976) situated along the coast of the Gooimeer (one of the peripheral lakes), the second and largest was to fulfill the role of city centre as Almere-Stad (1980) and the third was Almere-Buiten (1984) to the northwest towards Lelystad. In 2003, the municipality made a new Structuurplan which started development of three new settlements: Overgooi in the southeast, Almere-Hout in the east, and Almere-Poort in the West. In time, Almere-Pampus could be developed in the northwest, with possibly a new bridge over the IJmeer towards Amsterdam.

The Oostvaardersplassen is a landscape of shallow pools, islets and swamps. Originally, this low part of the new polder was destined to become an industrial area. Spontaneous settlement of interesting flora & fauna turned the area into a nature park, of such importance that the new railway-line was diverted. The recent decline in agricultural land use will in time make it possible to expand natural land use, and connect the Oostvaardersplassen to the Veluwe.

The centre of the polder most closely resembles the pre-war polders in that it is almost exclusively agricultural. In contrast, the southeastern part is dominated by extensive forests. Here is also found the only other settlement of the polder, Zeewolde (1984), again a more conventional town acting as the local centre. Zeewolde became a municipality at the same time as Almere on January 1, 1984, which in the case of Zeewolde meant that the municipality existed before the town itself, with only farms in the surrounding land to be governed until the town started to grow.
