Located in the south-west of the country close to the international border with Togo, the hydroelectric dam at Kompienga, built in the 1980s, is one of the largest in the country, with a capacity of 2,000,000 m3 of water. The sites includes the lake and a 5-km strip of surrounding savanna, the vegetation of which is typical of the Pendjari–Mékrou sector of the southern Sudan savanna while, in places close to the lake shore, the shrub- and tree-savanna is now developing into gallery forest.
See Box and Table 2 for key species. There is, as yet, little ornithological information available; it is, however, thought more than 20,000 waterbirds regularly occur, amongst which Phalacrocorax africanus, Egretta garzetta and Bubulcus ibis are common.
Non-bird biodiversity: There is little information but it is known that Loxodonta africana (EN) and the occasional Damaliscus lunatus korrigum (LR/cd) come to the lake during the dry season.
