The Euphrates River runs 1,700 miles from the mountains of eastern Turkey to the Persian Gulf.
Notes on verification
Multiple independent tertiary sources corroborate the ~1,700-mile length and the geography (source in eastern Turkey's mountains, mouth at Persian Gulf), though exact figures vary slightly (1,678-1,740 miles) due to measurement methodology differences, which is typical for river-length claims.
