The canal Butter deep runs in the province of Groningen from the port of Uithuizen to the Van Starkenborghkanaal at Noorderhoogebrug (city of Groningen) and is 25 km. long. The channel is said to owe its name to the transport of milk products. Other names that were in vogue for the Boterdiep are: Butterdiep, Botterdiep, Butterdep or Cleisloot. In Groningen: Botterdaip.
During construction in the 17e century, existing watercourses were used. The connection from Bedum to Groningen was dug by the Cleisloot in 1625. In 1660 it was extended to Kantens. In 1695 the harbor in Uithuizen became a reality.
For the construction of the Van Starkenborghkanaal, it ended deep in the Turfsingel in the city of Groningen.
