Contours of Lake Nasser, Egypt and Sudan22.5N 31.7E
Lake Nasser is a vast reservoir on the Nile River in southern Egypt and northern Sudan. 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. Here, the Sudanese part appears greenish due to sediments and algae, while the Egyptian part appears dark blue.
It is one of the largest man-made lakes in the world. The lake is some 550 km long and 35 km across at its widest point, which is near the Tropic of Cancer. It covers a total surface area of 5,250 km² and has a storage capacity of some 157 km³ of water. The area of Sudan-administered Wadi Halfa Salient was largely flooded by Lake Nasser. Visible near the left edge are the Toshka Lakes, created by overflow.
