Lake Gabou

Lake Gabou (بحيرة كب, Lac Gabou, Hoorewendu) is a lake and wetlands area in Tagant Region of Mauritania. It captures runoff from the Tagant plateau and supports a range of indigenous flora and fauna, including Phoenix dactylifera and Hyphaene thebaica, two economically important palm species, and Adansonia digitata and Adenium obesum. It is also a refuge for the West African crocodile and migrating birds. It was designated a Ramsar convention site in 2009.

Historically, the lake and the basin around it were also known as Tammourt en Naaj (تمورت والنجا) or Hoorewendu, meaning 'head of the swamp' in Pulaar, and sheltered a population of hippopotami.
