Contours of Lake Nasser, Egypt and Sudan

Egypt – November 16th, 2012

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.

Lake Nasser Providing Water for New Valley Project, Egypt

Egypt - May 8th, 2012

Lake Nasser, created as a result of the construction of the Aswan High Dam across the waters of the Nile between 1958 and 1971, is an important water source for Egypt (above) and Sudan (below). Visible to its west are the Toshka Lakes, filled by the overflow from Lake Nasser.

Some areas of agriculture can be seen in this extremely arid region, irrigated by Lake Nasser’s waters. Crops can be observed near the Nile in the upper right quadrant, and by the center left edge of the image. The latter are part of the New Valley Project (click link for images of how the area has grown), a system of canals built to carry water from Lake Nasser to irrigate the sandy wastes of the Western Desert of Egypt, which is part of the Sahara Desert.

Nile River from Lake Nasser to Nile Delta, Egypt

Egypt - April 9th, 2012

The Nile River flows northward from Lake Nasser on the Sudan-Egypt border towards the bottom of this image, to the Nile Delta, the delta formed in Northern Egypt where the Nile spreads out and drains into the Mediterranean Sea. It is one of the world’s largest river deltas—from Alexandria in the west to Port Said in the east, it covers 240 km of Mediterranean coastline—and is a rich agricultural region. Numerous towns can be observed throughout the region as tan dots across the green terrain. From north to south the delta is approximately 160 km in length. The Delta begins slightly down-river from Cairo, which is only  partially visible at the stem of the delta due to cloud cover.

Visible at the right edge of this image is the southern part of Lake Nasser, on the Nile River by the border of Sudan (below) and Egypt (above). Northwest of the lake are the Toshka Lakes, a by-product of the rising level of Lake Nasser. The rectangular pattern of dots near the left edge of the image are the circular irrigated fields of the New Valley Project (Toshka project).

The New Valley Project consists of building a system of canals to carry water from Lake Nasser to irrigate the sandy wastes of the Western Desert of Egypt, which is part of the Sahara Desert. In 1997 the Egyptian government decided to develop a “new” valley (in addition to the Nile Valley) where agricultural and industrial communities could be developed. It is an ambitious project, that if successful, should help Egypt deal with its rapidly growing population. If the project fails it will exacerbate problems of allocating the scarce waters of the Nile.

The canal inlet starts from a site lying 8 km to the north of Toshka Bay (Khor) on Lake Nasser. The canal continues westward until it reaches Darb el-Arbe’ien route, then moves northward along Darb el- Arbe’ien to the Baris Oasis, covering a distance of 310 km. The Mubarak Pumping Station in Toshka is the centerpiece of the project and was inaugurated in March 2005. It pumps water from Lake Nasser to be transported by way of a canal through the valley, transforming 2340 km² (588,000 acres) of desert into agricultural land. When the Toshka Project is completed in 2020, the valley is projected to become home to more than three million residents and to increase Egypt’s arable land area by 10%.

Nile River and Lake Nasser in Sudan and Egypt

Egypt - October 19th, 2011

Lake Nasser is visible as a bluish green lake with jagged edges in the upper left quadrant of this image. It is a vast reservoir in southern Egypt and northern Sudan. The lake was created as a result of the construction of the Aswan High Dam across the waters of the Nile between 1958 and 1971.

The Nile River can be seen winding its way northward through Sudan and Lake Nasser and into Egypt. On the Egyptian side, it is flanked by a wide green, fertile valley. In Sudan, near the bottom of the image, it is used to irrigate the crops of the Gezira Scheme.
