Is a seasonal shallow endorheic salt lake on the floor of the Great Rift Valley at the base of the Serengeti Plateau, just south of the Serengeti National Park and immediately southwest of the Ngorongoro Crater in the Crater Highlands of Tanzania. The lake is elongated, orientated southwest to northeast, and lies in the Eyasi-Wembere branch of the Great Rift Valley.
The Hadza are the indigenous inhabitants of the lake. They are found along most of the perimeter, though camps are few along most of the Serengeti, which is Maasai territory. The Datooga inhabit the Yaeda Valley to the southeast, the Isanzu the south, and the Sukuma across the Sibiti River in the southwest. The Iraqw traditionally lived on the other side of Yaeda, but have come in increasing numbers to the Baray, which is now the primary onion-growing region of East Africa.
