Turkey - May 17th, 2009

Three reservoirs created by dams on the Euphrates River are visible here in the southeastern Anatolia region of  Turkey. From top to bottom, they are the lakes of the  Keban Dam, Karakaya Dam and Atatürk Dam.

Lake Atatürk Dam extends over an area of 817 km2 (315 sq mi), with a water volume of 48.7 km³ (63,400 million cu yd), and ranks third in size in Turkey after Lake Van and Lake Tuz.

The reservoir water level touched 535 m amsl in 1994. Since then, it has varied between 526 and 537 m amsl. The full reservoir level is 542 m (1,780 ft) and the minimum operation level is 526 m (1,730 ft) amsl.

Between the Keban and Karakaya Reservoirs, slightly east, is a natural lake, Lake Hazar. It is located in the Taurus Mountains, southeast of Elazig, and is notable as the source of the Tigris.

Karaca Volcano and Ataturk Dam, Turkey - January 13th, 2009

Karaca Volcano and Ataturk Dam, Turkey - January 13th, 2009

Snow covers the Taurus Mountains in southeastern Anatolia region of Turkey and caps the summit of the Karaca volcano (center right), a shield volcano.

The lake surrounded by snow, north of Karaca, is called Lake Hazar (Hazar Gölü); it is notable as the source of the Tigris River.

The large body of water in the lower left quadrant was created by the Atatürk Dam (Turkish: Atatürk Barajı),  on the Euphrates River.

The Atatürk Dam, one of the five operational dams on the Euphrates as of 2008, is preceded by Keban and Karakaya dams upstream.

The Euphrates is the western of the two great rivers that define Mesopotamia (the other being the Tigris) which flows from Anatolia. The river is approximately 2,781 kilometers (1,730 mi) long.

In the main image on the left, we can see a part of the Euphrates River that runs down from Turkey and across Syria. The Turkish-Syrian border is visible in the upper portion of the image as a change in terrain and color. On the left we have Lake Assad (Buhayrat al Asad) in Syria, and in the top left corner, the Ataturk Dam in Turkey. Slightly right of the center is the confluence of the Euphrates and Khabur Rivers, near the town of Busayrah. Along the river we see green patches hugging the banks; these is mostly from agriculture.

The Euphrates River is formed by the union of two branches: the Kara Su and the Murat Nehri. Their courses run fairly parallel in a westerly direction until they unite near the city of Keban, at an elevation of about 610 m (2,000 ft) above sea level. From this point on, the combined streams form the Euphrates proper.

The upper reaches of the Euphrates flow through steep canyons and gorges, southeast across Syria, and through Iraq. The Khabur (see close-up) and the Balikh River join the Euphrates in eastern Syria. The Euphrates finally emerges on the Syrian plain at a point north of the site of ancient Carchemish (modern Jerablus). Both rivers have their origins in Turkey.

Downstream, through its whole length, the Euphrates has no other notable tributaries. North of Basra, in southern Iraq, the river merges with the Tigris to form the Shatt al-Arab, this in turn empties into the Persian Gulf.

The river used to divide into many channels at Basra, forming an extensive marshland, but the marshes were largely drained by the Saddam Hussein government in the 1990s as a means of driving out the rebellious Marsh Arabs. Since the 2003 invasion of Iraq, the drainage policy has been reversed, but it remains to be seen whether the marshes will recover.

The Euphrates is only navigable by very shallow-draft boats, which can reach as far as the Iraqi city of Hit, located 1,930 kilometers (1,200 mi) upstream and only 60 meters (200 ft) above sea level. Above Hit, however, shoals and rapids make the river commercially unnavigable. Its annual inundation, caused by snow melt in the mountains of northeastern Turkey, has been partly checked by new dams and reservoirs in the upper reaches. An 885-kilometer (550 mi) canal links the Euphrates to the Tigris to serve as a route for river barges.
