Itonomas River

The third one in Top 9 Longest Rivers in Bolivia that Toplist wants to introduce to you is Itonomas River. The Itonomas River flows through the Bolivian departments of Santa Cruz and Beni. It is a tributary of the Amazon River. The San Julián River, which begins near Concepción Lake at the confluence of the intermittent Quimome and Santa Maria Rivers as the San Julián River, flows north until it becomes the San Pablo River near Ascensión de Guarayos, at which point it forms part of the border between the Beni and Santa Cruz Departments. It then flows further north into the Beni Department, and after passing by the small Lake El Bi, it becomes the San Luis River, which it retains for a short distance before becoming the Itonomas River at its confluence with the Lopez River.

Despite its length, the Itonomas is nominally considered a tributary of the shorter Machupo River, which drains into the Iténez River only a short distance downstream. Furthermore, because its headwaters are located on the eastern edge of the vast Baados del Izozog, the Itonomas can be considered a hydrological continuation of the Parapet River, which originates in the Bolivian Andes.

It receives tributaries such as the Quizer River along its path.
