Discharge
The Euphrates receives most of its water in the form of rainfall and melting snow, resulting in peak volumes during the months April through May. Discharge in these two months accounts for 36 percent of the total annual discharge of the Euphrates, or even 60–70 percent according to one source, while low runoff occurs in summer and autumn. The average natural annual flow of the Euphrates has been determined from early- and mid-twentieth century records as at Keban, at Hīt and at Hindiya. However, these averages mask the high inter-annual variability in discharge; at Birecik, just north of the Syro–Turkish border, annual discharges have been measured that ranged from a low volume of in 1961 to a high of in 1963.
The discharge regime of the Euphrates has changed dramatically since the construction of the first dams in the 1970s. Data on Euphrates discharge collected after 1990 show the impact of the construction of the numerous dams in the Euphrates and of the increased withdrawal of water for irrigation. Average discharge at Hīt after 1990 has dropped to per second ( per year). The seasonal variability has equally changed. The pre-1990 peak volume recorded at Hīt was per second, while after 1990 it is only per second. The minimum volume at Hīt remained relatively unchanged, rising from per second before 1990 to per second afterward.

of the Tishrin Dam. The Balikh receives most of its water from a karstic spring near 'Ayn al-'Arus and flows due south until it reaches the Euphrates at the city of Raqqa. In terms of length, drainage basin and discharge, the Khabur is the largest of these three. Its main karstic springs are located around Ra's al-'Ayn, from where the Khabur flows southeast past Al-Hasakah, where the river turns south and drains into the Euphrates near Busayrah. Once the Euphrates enters Iraq, there are no more natural tributaries to the Euphrates, although canals connecting the Euphrates basin with the Tigris basin exist.

zones. Although millennia-long human occupation in most parts of the Euphrates basin has significantly degraded the landscape, patches of original vegetation remain. The steady drop in annual rainfall from the sources of the Euphrates toward the Persian Gulf is a strong determinant for the vegetation that can be supported. In its upper reaches the Euphrates flows through the mountains of Southeast Turkey and their southern foothills which support a xeric woodland. Plant species in the moister parts of this zone include various oaks, pistachio trees, and ''Rosaceae

River
The Hindiya Barrage on the Iraqi Euphrates, based on plans by British civil engineer William Willcocks and finished in 1913, was the first modern water diversion structure built in the Tigris–Euphrates river system. The Hindiya Barrage was followed in the 1950s by the Ramadi Barrage and the nearby Abu Dibbis Regulator, which serve to regulate the flow regime of the Euphrates and to discharge excess flood water into the depression that is now Lake Habbaniyah. Iraq's largest dam on the Euphrates is the Haditha Dam; a earth-fill dam creating Lake Qadisiyah. Syria and Turkey built their first dams in the Euphrates in the 1970s. The Tabqa Dam in Syria was completed in 1973 while Turkey finished the Keban Dam, a prelude to the immense Southeastern Anatolia Project, in 1974. Since then, Syria has built two more dams in the Euphrates, the Freedom Dam and the Tishrin Dam, and plans to build a fourth dam – the Halabiye Dam – between Raqqa and Deir ez-Zor. The Tabqa Dam is Syria's largest dam and its reservoir ( Lake Assad) is an important source of irrigation and drinking water. It was planned that should be irrigated from Lake Assad, but in 2000 only had been realized. Syria also built three smaller dams on the Khabur and its tributaries.
With the implementation of the Southeastern Anatolia Project (', or ''GAP'') in the 1970s, Turkey launched an ambitious plan to harness the waters of the Tigris and the Euphrates for irrigation and hydroelectricity production and provide an economic stimulus to its southeastern provinces. GAP affects a total area of and approximately 7 million people; representing about 10 percent of Turkey's total surface area and population, respectively. When completed, GAP will consist of 22 dams – including the Keban Dam – and 19 power plants and provide irrigation water to of agricultural land, which is about 20 percent of the irrigable land in Turkey. C. of this irrigated land is located in the Euphrates basin. By far the largest dam in GAP is the Atatürk Dam, located c. northwest of Şanlıurfa. This dam was completed in 1992; thereby creating a reservoir that is the third-largest lake in Turkey. With a maximum capacity of , the Atatürk Dam reservoir is large enough to hold the entire annual discharge of the Euphrates. Completion of GAP was scheduled for 2010 but has been delayed because the World Bank
The World Bank is an international financial institution that provides loans and Grant (money), grants to the governments of Least developed countries, low- and Developing country, middle-income countries for the purposes of economic development ...
has withheld funding due to the lack of an official agreement on water sharing between Turkey and the downstream states on the Euphrates and the Tigris.
Apart from barrages and dams, Iraq has also created an intricate network of canals connecting the Euphrates with Lake Habbaniyah, Lake Tharthar, and Abu Dibbis reservoir; all of which can be used to store excess floodwater. Via the Shatt al-Hayy
The Gharraf Canal, Shaṭṭ al-Ḥayy (Arabic: شط الحي), also known as Shaṭṭ al-Gharrāf (Arabic: شط الغرّاف) or the Hai river, is an ancient canal in Iraq that connects the Tigris at Kut al Amara with the Euphrates east of Nas ...

Environmental and social effects
The construction of the dams and irrigation schemes on the Euphrates has had a significant impact on the environment and society of each riparian country. The dams constructed as part of GAP – in both the Euphrates and the Tigris basins – have affected 382 villages and almost 200,000 people have been resettled elsewhere. The largest number of people was displaced by the building of the Atatürk Dam, which alone affected 55,300 people. A survey among those who were displaced showed that the majority were unhappy with their new situation and that the compensation they had received was considered insufficient. The flooding of Lake Assad led to the forced displacement of c. 4,000 families, who were resettled in other parts of northern Syria as part of a now abandoned plan to create an " Arab belt" along the borders with Turkey and Iraq.
Apart from the changes in the discharge regime of the river, the numerous dams and irrigation projects have also had other effects on the environment. The creation of reservoirs with large surfaces in countries with high average temperatures has led to increased evaporation
Evaporation is a type of vaporization that occurs on the Interface (chemistry), surface of a liquid as it changes into the gas phase. A high concentration of the evaporating substance in the surrounding gas significantly slows down evapora ...
; thereby reducing the total amount of water that is available for human use. Annual evaporation from reservoirs has been estimated at in Turkey, in Syria and in Iraq. Water quality in the Iraqi Euphrates is low because irrigation water tapped in Turkey and Syria flows back into the river, together with dissolved fertilizer chemicals used on the fields. The salinity of Euphrates water in Iraq has increased as a result of upstream dam construction, leading to lower suitability as drinking water. The many dams and irrigation schemes, and the associated large-scale water abstraction, have also had a detrimental effect on the ecologically already fragile Mesopotamian Marshes and on freshwater fish habitat

Occupation of lower Mesopotamia started in the 6th millennium and is generally associated with the introduction of irrigation, as rainfall in this area is insufficient for dry agriculture. Evidence for irrigation has been found at several sites dating to this period, including Tell es-Sawwan.

from 1932 to 1959.
Turkey and Syria completed their first dams on the Euphrates – the Keban Dam and the Tabqa Dam, respectively – within one year of each other and filling of the reservoirs commenced in 1975. At the same time, the area was hit by severe drought and river flow toward Iraq was reduced from in 1973 to in 1975. This led to an international crisis during which Iraq threatened to bomb the Tabqa Dam. An agreement was eventually reached between Syria and Iraq after intervention by Saudi Arabia and the Soviet Union

. A similar crisis, although not escalating to the point of military threats, occurred in 1981 when the Keban Dam reservoir had to be refilled after it had been almost emptied to temporarily increase Turkey's hydroelectricity production. In 1984, Turkey unilaterally declared that it would ensure a flow of at least per second, or per year, into Syria, and in 1987 a bilateral treaty to that effect was signed between the two countries. Another bilateral agreement from 1989 between Syria and Iraq settles the amount of water flowing into Iraq at 60 percent of the amount that Syria receives from Turkey. In 2008, Turkey, Syria and Iraq instigated the Joint Trilateral Committee (JTC) on the management of the water in the Tigris–Euphrates basin and on 3 September 2009 a further agreement was signed to this effect.
On 15 April 2014, Turkey began to reduce the flow of the Euphrates into Syria and Iraq. The flow was cut off completely on 16 May 2014 resulting in the Euphrates terminating at the Turkish–Syrian border. This was in violation of an agreement reached in 1987 in which Turkey committed to releasing a minimum of of water per second at the Turkish–Syrian border.
