Lake Almere was an inland lake in the place of today's IJsselmeer in the center of the Netherlands.
The texts of ancient Romans called it Lake Flevo.[ citation needed ] Lake Almere is mentioned among others in a life of saints written by Anglo-Saxon Bishop Saint Boniface in 753, and a deed of gift from the town of Urk.[ citation needed ]
Its etymology may be eels, in Dutch aal or ael, so: "ael mere" = "eel lake"[ citation needed ]
Presumably, the water of Lake Almere at that time was fresh water or slightly brackish.[ citation needed ]
A number of occurrences during the Middle Ages led to the transformation of the lake to an inland sea that would be called the Zuiderzee, which are:
The name of the new town of Almere in Flevoland was given in 1984 in memory of this body of water.

Flevoland is the 12th and youngest 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 1,412 km2 (545 sq mi), but not gross land as that includes much of the waters of the fresh water lakes (meres) mentioned.
Lelystad is a municipality and a city in the centre of the Netherlands, and it is the capital of the province of Flevoland. The city, built on reclaimed land, was founded in 1967 and was named after Cornelis Lely, who engineered the Afsluitdijk, making the reclamation possible. Lelystad is approximately 3 metres below sea level. It is located about 20 km north east of Almere and 40 km west of Zwolle.
The IJsselmeer, also known as Lake IJssel in English, is a closed off inland bay in the central Netherlands bordering the provinces of Flevoland, North Holland and Friesland. It covers an area of 1,100 km2 (420 sq mi) with an average depth of 5.5 m (18 ft). The river IJssel flows into the IJsselmeer.
The Zuiderzee or Zuider Zee was a shallow bay of the North Sea in the northwest of the Netherlands, extending about 100 km inland and at most 50 km wide, with an overall depth of about 4 to 5 metres (13–16 feet) and a coastline of about 300 km. It covered 5,000 km2 (1,900 sq mi). Its name is Dutch for "southern sea", indicating that the name originates in Friesland, to the north of the Zuiderzee. In the 20th century the majority of the Zuiderzee was closed off from the North Sea by the construction of the Afsluitdijk, leaving the mouth of the inlet to become part of the Wadden Sea. The salt water inlet changed into a fresh water lake now called the IJsselmeer after the river that drains into it, and by means of drainage and polders, an area of some 1,500 km2 (580 sq mi) was reclaimed as land. This land eventually became the province of Flevoland, with a population of nearly 400,000 (2011).
The IJssel is a Dutch distributary of the river Rhine that flows northward and ultimately discharges into the IJsselmeer, a North Sea natural harbour. It more immediately flows into the east-south channel around the Flevopolder, Flevoland which is kept at 3 metres below sea level. This body of water is then pumped up into the IJsselmeer.
The Zuiderzee Works is a man-made system of dams and dikes, land reclamation and water drainage work, in total the largest hydraulic engineering project undertaken by the Netherlands during the twentieth century. The project involved the damming of the Zuiderzee, a large, shallow inlet of the North Sea, and the reclamation of land in the newly enclosed water using polders. Its main purposes are to improve flood protection and create additional land for agriculture.
Urk is a municipality and a town in the Flevoland province in the central Netherlands.
Zeewolde is a municipality and a town in the Flevoland province in the central Netherlands. It has a population of approximately 22,000 (2017). It is situated in the polder of Flevoland with the small lake called the Wolderwijd to the east. To the south is a large deciduous forest called the Horsterwold. The area to the west is principally agricultural.
Wieringermeer is a former municipality and a polder in the Netherlands, in the province of North Holland. Since 2012 Wieringermeer has been a part of the new municipality of Hollands Kroon.
The Afsluitdijk is a major dam and causeway in the Netherlands. It was constructed between 1927 and 1932 and runs from Den Oever in North Holland province to the village of Zurich in Friesland province, over a length of 32 kilometres (20 mi) and a width of 90 metres (300 ft), at an initial height of 7.25 metres (23.8 ft) above sea level.
The Vecht is a Rhine branch in the Dutch province of Utrecht. It is sometimes called Utrechtse Vecht to avoid confusion with its Overijssel counterpart. The area along the river is called the Vechtstreek.
The IJ is a body of water, formerly a bay, in the Dutch province of North Holland. It is known for being Amsterdam's waterfront.
Sailing/Yachting is an Olympic sport starting from the Games of the 1st Olympiad. With the exception of 1904 and the canceled 1916 Summer Olympics, sailing has always been included on the Olympic schedule. The Sailing program of 1928 consisted of a total of three sailing classes. For each class races were scheduled from 2–9 August 1928 on the Buiten Y near Amsterdam and on the Zuiderzee. The sailing was done on the triangular type Olympic courses.
The Vlie or Vliestroom is the seaway between the Dutch islands of Vlieland, to its southwest, and Terschelling, to its northeast. The Vlie was the estuary of the river IJssel in medieval times. In 1666 the English Admiral Robert Holmes burnt a Dutch merchant fleet of 130 ships, that had taken refuge in the Vlie, mistakenly supposing the English could never find their way through the treacherous shoals along its coastline. Today it's still possible to reach the port of Harlingen by way of the Vlie.
The Zuiderzee Museum, located on Wierdijk in the historic center of Enkhuizen, is a Dutch museum devoted to preserving the cultural heritage and maritime history from the old Zuiderzee region. With the closing of the Afsluitdijk on May 28, 1932, the Zuiderzee was split in two parts: the waters below the Afsluitdijk are now called the IJsselmeer, while the waters north of it are now considered to be part of the Waddenzee.
Flood control is an important issue for the Netherlands, as due to its low elevation, approximately two thirds of its area is vulnerable to flooding, while the country is densely populated. Natural sand dunes and constructed dikes, dams, and floodgates provide defense against storm surges from the sea. River dikes prevent flooding from water flowing into the country by the major rivers Rhine and Meuse, while a complicated system of drainage ditches, canals, and pumping stations keep the low-lying parts dry for habitation and agriculture. Water control boards are the independent local government bodies responsible for maintaining this system.
The All Saints' Flood of 1170 (Allerheiligenvloed) was a catastrophic flood in the Netherlands that took place in 1170. Large parts of the Northern Netherlands, and Holland territories were overflowed.
Lake Flevo was a lake in what is now the Netherlands, which existed in Roman times and the early Middle Ages. Some geographers believe that this lake was not really a single lake, rather a set of several lakes connected to each other.
The Rhine–Meuse–Scheldt delta is a river delta in the Netherlands formed by the confluence of the Rhine, the Meuse and the Scheldt rivers. In some cases, the Scheldt delta is considered a separate delta to the Rhine–Meuse delta. The result is a multitude of islands, branches and branch names that may at first sight look bewildering, especially as a waterway that appears to be one continuous stream may change names as many as seven times, e.g. Rhine → Bijlands Kanaal → Pannerdens Kanaal → Nederrijn → Lek → Nieuwe Maas → Het Scheur → Nieuwe Waterweg. Since the Rhine contributes most of the water, the shorter term Rhine Delta is commonly used. However, this name is also used for the delta where the Alpine Rhine flows into Lake Constance, so it is clearer to call the larger one Rhine–Meuse delta, or even Rhine–Meuse–Scheldt delta, as the Scheldt ends in the same delta. By some calculations, the delta covers 25,347 km2 (9,787 sq mi), making it the largest in Europe.
The Markermeer is a 700 km2 (270 sq mi) lake in the central Netherlands in between North Holland, Flevoland, and its smaller and larger neighbors, the IJmeer and IJsselmeer. A shallow lake at 3 to 5 m in depth, matching the reclaimed land to its west, north-west and east it is named after the small former island, now peninsula, of Marken on its west shore.
