Apamea lies below these waters
Apamea or Apameia (Greek: Απάμεια) was a Hellenistic city on the left (viz.,the east) bank of the Euphrates, opposite the famous city of Zeugma, at the end of a bridge of boats (Greek: zeugma) connecting the two, founded by Seleucus I Nicator (Pliny, v. 21). The city was rebuilt by Seleucus I. The site, once partially covered by the village of Tilmusa (formerly Rumkale), Şanlıurfa Province, Turkey, is now flooded by the lake formed by the Birecik Dam (Birejik Dam).
