Bydgoszcz Canal is a canal, 24.7 km long, between the cities of Bydgoszcz and Nakło in Poland, connecting Vistula river with Oder river, through Brda and Noteć rivers (the latter ending in the Warta river which itself ends in Oder). The level difference along the canal is regulated with usage of 6 locks. The canal was built in 1772-1775, at the order of Frederick II, king of Prussia (after annexation of western Poland by Kingdom of Prussia in First Partition of Poland).
