Course
edit
The Oso is 23.27 kilometres (14.46 mi) long. It crosses the communes of Lecci, Porto-Vecchio, San-Gavino-di-Carbini and Zonza.[1] The Oso rises to the southwest of the 1,381 metres (4,531 ft) Monte Calva.[2] The source is in the territorial forest of L'Ospedale at an altitude of 980 metres (3,220 ft) about 1 kilometre (0.62 mi) northeast of the 1,227 metres (4,026 ft) Punta di u Diamante.[3]
In its upper section the stream is called the Ruisseau de Piscia di Ghjaddu. A waterfall on this section is one of the regional tourist attractions.[3] It flows southwest, then southeast, and receives the Ruisseau de Palavesani from the right, which drains the Ospedale Reservoir. It then flows east and then south, then turns west to enter Stagnolu Bay to the west of Saint-Cyprien.[2] There are beautiful natural pools for swimming in the mountainous section and in the plains.[3]
Hydrology
editMeasurements of the river flow were taken at the Lecci station from 1968 to 1980. The watershed above this station covers 46.2 square kilometres (17.8 sq mi). Annual precipitation was calculated as 660 millimetres (26 in). The average flow of water throughout the year was 0.962 cubic metres per second (34.0 cu ft/s).[4]
