The Mare d'Ossolo (also: Mare de N'Solo ) is a lake in the municipality of Téra in western Niger .

geography

The Mare d'Ossolo is located around 30 kilometers northwest of the city center of Téra, the capital of the Téra department of the same name in the Tillabéri region . The area of ​​the lake varies greatly depending on the season. In December, it reaches about 80 hectares and has an approximately oval shape.

The Dargol , a tributary of the Niger River , flows through the Mare d'Ossolo. On its west bank there is a large, wooded wetland on clayey soil. The lake is climatically in the Sahel zone . The defining winds are the harmattan and the monsoon .

colonization

Songhai , Fulbe and Iklan live in the area around the lake . A major Songhai village is Bégorou Tondo, which had 1786 inhabitants in the 2012 census. The Fulbe and Iklan are traditionally semi-nomadic. The Fulbe inhabit several camps in the west of the lake. The Iklan, formerly slaves of the Tuareg of Bankilaré , settle in the south and southwest of the Mare d'Ossolo.

Economical meaning

Along with the reservoir at the Téra dam and the Mare de Tabalak , the Mare d'Ossolo is one of the most important still waters in Niger used for fishing . The people of the surrounding hamlets practice fishing from November to February. After being smoked by women, the fish are sold in the markets in the surrounding villages and through fish wholesalers in the center of Téra. The land around the lake is also important for pasture farming.
