Lake Nasser (Arabic: بحيرة ناصر‎ Boħēret Nāṣer, Egyptian Arabic: [boˈħeːɾet ˈnɑːsˤeɾ]) is a vast reservoir in southern Egypt, and northern Sudan, and is one of the largest man-made lakes in the world. Strictly, "Lake Nasser" refers only to the much larger portion of the lake that is in Egyptian territory (83% of the total), with the Sudanese preferring to call their smaller body of water Lake Nubia (Egyptian Arabic: بحيرة نوبية Boħēret Nubeyya, [boˈħeːɾet nʊˈbejjæ]). The area of Sudan-administered Wadi Halfa Salient was largely flooded by Lake Nasser.
