12inch x 18inch Poster The Zuiderzee was a shallow bay of the North Sea in the northwest of the Netherlands, extending about 100 km (60 miles) inland and at most 50 km (30 miles) wide, with an overall depth of about 4 to 5 metres (13-16 feet) and a coastline of about 300 km (200 miles). It covered 5,000 km (2,000 square miles). Its name means "southern sea" in Dutch, indicating that the origin of the name can be found in Friesland to the north of the Zuiderzee (also see North Sea). In the 20th century the majority of the Zuiderzee was closed off from the North Sea (leaving the mouth of the inlet to become part of the Wadden Sea) and the salt water inlet changed into a fresh water lake called the IJsselmeer (IJssel-lake) after the river that drains into it. The river IJssel is an estuary branch of the river Rhine . - There is a border around the image. Image size is correct.
