Map of the Sakarya River

The Sakarya (Turkish: Sakarya Irmağı, Greek: Σαγγάριος, translit. Sangarios) is the third longest river in Turkey. It runs through what in ancient times was known as Phrygia.

The source of the river is the Bayat Yaylası (Bayat Plateau) which is located to the northeast of Afyon. Joined by the Porsuk Çayı (Porsuk Creek) close by the town of Polatlı, the river runs through the Adapazarı Ovası (Adapazarı Plains) before reaching the Black Sea. The Sakarya was once crossed by the Sangarius Bridge, constructed by the East Roman Emperor Justinian I (r. 527–565).

In 13th century, the valley of the Sakarya was part of the frontier of the Byzantine Empire and the home of the Söğüt tribe. By 1280, Byzantine Emperor Michael VIII had constructed a series of fortifications along the river to control the area, but a 1302 flood changed the course of the river and made the fortifications useless.[1] The Söğüt tribe migrated across the river and went on to establish the Ottoman Empire.

From downstream to upstream, it is dammed at Gölpazarı, Yenice, Gökçekaya and Sarıyar.
