where does the yenisei river begin and end

The Yenisei River is one of the major rivers in Russia. It begins in Mongolia and flows northwards through Siberia before emptying into the Kara Sea, which is part of the Arctic Ocean. Here are more details about its course:

Source: The Yenisei River originates from two main tributaries, the Kara-Khem River and the Mungaragiyn-Gol, in the Tuva Republic of Mongolia. These tributaries merge near the Mongolian-Russian border to form the Upper Yenisei.

Flow: After its formation, the Yenisei River flows northward through southern Siberia, passing through the Yenisei Gulf, the largest estuary of the Kara Sea.
