Lake Basaka (Oromo: Hora Basakaa; Amharic: በሰቃ ሐይቅ) is a shallow, saline lake in the Oromia Region of central Ethiopia.

It is located in the Great Rift Valley about 200 kilometres (120 mi) south east of the capital Addis Ababa.

The lake is growing to the east and northeast due to the local topography.

[1] Due to the growth of the lake, there is an increasing concern that it will permanently damage the nearby Awash River, which is a major water source for nearby cotton and sugar plantations.

The water salinity is also affecting the area groundwater as the salinity levels have increased in most plantation sections,[1] and local sugar refineries have reduced production rates due to the loss of growing area.
