The Euphrates is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia.
Explanation:
The Euphrates is important solely for its water supply. The river is the source of political tension, as Turkey, Syria and Iraq all compete for the use of its waters for irrigation and the generation of hydroelectric power. For centuries the river formed the east limit of Roman control. “There is no water!” The Euphrates is drying up. Strangled by the water policies of Iraq's neighbors, Turkey and Syria; a two-year drought; and years of misuse by Iraq and its farmers, the river is significantly smaller than it was just a few years ago. Some officials worry that it could soon be half of what it is now.

Jonas is surprised because no doors are ever locked. The attendant tells Jonas the locks are for privacy, which the Receiver needs to do his job.
