context_page_description: Nidau is a municipality in the Biel/Bienne administrative district in the canton of Bern in Switzerland.
context_section_description: The city is located at the city limits of Biel/Bienne and both cities have grown intertwined. Since the Jura water correction, the medieval centre and a good portion of the city of Nidau are now actually located on an island, created by the Nidau-Büren Aare canal, the river Thielle in French or Zihl in German, and the Lake Biel's shore.
  Nidau has an area of 1.52 km² (0.59 sq mi).  As of 2012, none of the land is used for agricultural purposes, while 0.06 km² (0.023 sq mi) or 3.9% is forested.  Of the rest of the land, 1.28 km² (0.49 sq mi) or 84.2% is settled (buildings or roads), 0.18 km² (0.069 sq mi) or 11.8% is either rivers or lakes.
  During the same year, industrial buildings made up 6.6% of the total area while housing and buildings made up 46.1% and transportation infrastructure made up 17.1%.  Power and water infrastructure as well as other special developed areas made up 2.6% of the area while parks, green belts and sports fields made up 11.8%.  Out of the forested land, 2.0% of the total land area is heavily forested and 2.0% is covered with orchards or small clusters of trees.  Of the water in the municipality, 0.7% is in lakes and 11.2% is in rivers and streams.
  On 31 December 2009 Amtsbezirk Nidau, the municipality's former district, was dissolved.  On the following day, 1 January 2010, it joined the newly created Verwaltungskreis Biel/Bienne.
