How does the Akhtuba River reach the Caspian Sea?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

The Akhtuba River does not reach the Caspian Sea as a separate entity; rather, it is the main distributary of the Volga River.

Branching off from the Volga above Volgograd, the Akhtuba flows southeastward, running parallel to the main course of the Volga. The area between the two rivers forms a floodplain characterized by a network of interconnecting channels and loops. Ultimately, the Akhtuba is part of the extensive Volga delta, which discharges into the Caspian Sea.12
