Sadak

The Sadak rises near Matveyevka and flows to the Dyoma, joining it from the left near Dmitriyevka. Its waters belong to the Kama basin: the Dyoma joins the Belaya, which continues north to the Kama and thence to the Volga. The Sadak drains a network of small tributaries and lakes in the country between the Samara and Belaya river systems. Its valley lies in a region of steppe and woodland west of the southern Urals.
