In the Netherlands, the bordering lakes (in Dutch: Randmeren) are a chain of lakes which separate the Flevopolder and Noordoostpolder from the ancient lands of the provinces of Gelderland, Utrecht, Overijssel and Friesland.
Strictly speaking, these 'lakes' are not separated from each other, but are a continuous body of water between the old land and the new polder lands, consisting of lakes divided by straits, dams, locks, or in some cases just a bridge over narrow water.
The Wolderwijd is a bordering lake situated in the Netherlands, created in 1967 by the gaining of land in Southern Flevoland. It is one of four Veluwe bordering lakes. On the northern and western bank it is encompassed by the municipality of Zeewolde, in the Province of Flevoland, and on the southern and eastern bank it is encompassed by the municipality of Harderwijk in the Province of Gelderland. As the bordering lakes of Flevoland are strictly speaking one mass of water there are no exact markers on where the Wolderwijd ends and the adjacent lakes start. In the west near Strand Horst the Wolderwijd becomes the Nuldernauw and in the east at the aqueduct at the provincial road N302 it becomes the Veluwemeer.
Flevoland (Dutch pronunciation: [ˈfleːvoːlɑnt] ) is the twelfth and newest province of the Netherlands, established in 1986, when the southern and eastern Flevopolders, together with the Noordoostpolder, were merged into one provincial entity. It is in the centre of the country in the former Zuiderzee, which was turned into the freshwater IJsselmeer by the closure of the Afsluitdijk in 1932. Almost all of the land belonging to Flevoland was reclaimed in the 1950s and 1960s while splitting the Markermeer and bordering lakes from the IJsselmeer. As to dry land, it is the smallest province of the Netherlands at 1,410 km (540 sq mi), but not gross land as that includes much of the waters of the fresh water lakes (meres) mentioned.
The province had a population of about 445,000 as of January 2023 and consists of six municipalities. Its capital is Lelystad and its most populous city is Almere, which forms part of the Randstad and has grown to become the seventh largest city of the country. Flevoland is bordered in the extreme north by Friesland, in the northeast by Overijssel, and in the northwest by the lakes Markermeer and IJsselmeer. In the southeast, the province borders on Gelderland; in the southwest on Utrecht and North Holland. Outside urban areas, the land in Flevoland is predominantly used for agriculture.
The IJmeer is a 'bordering lake' (Randmeer) in the Netherlands straddling the provinces of North Holland and Flevoland. Namely, it is the southwestern section of the Markermeer. It is an important habitat for birds such as the tufted duck and scaup.
