The 19th arrondissement of Paris (XIX arrondissement) is one of the 20 arrondissements of the capital city of France. In spoken French, this arrondissement is referred to as dix-neuvième.
The arrondissement, known as Butte-Chaumont, is situated on the right bank of the River Seine. It is crossed by two canals, the Canal Saint-Denis and the Canal de l'Ourcq, which meet near the Parc de la Villette.
The Canal de l'Ourcq (French pronunciation: [kanal də luʁk]) is a 108.1 km (67.2 mi) long canal in the Île-de-France region (greater Paris) with 10 locks. It was built at a width of 3.20 m (10.5 ft) but was enlarged to 3.7 m (12 ft), which permitted use by more pleasure boats. The canal begins at Port-aux-Perches near the village of Troesnes, where it splits from the channeled river Ourcq, and flows to the Bassin de la Villette, where it joins the Canal Saint-Martin. Paris requires 380,000 cubic metres (84,000,000 imp gal; 100,000,000 US gal) of water daily for cleaning the sewer system, gutters, and parks. The Canal de l'Ourcq provides about half of the requirement. Since 1983, the waterway has been designated for use by pleasure craft, and its water is designated for non-drinking uses.
The canal is considered part of the 130 km (81 mi) Parisian canal network, along with the Canal Saint-Denis, the bassin de la Villette, and the Canal Saint-Martin. The canals were created as part of the administrative management of water in Paris during the nineteenth century.
