It then continues into further north into the Beni Department, and after flowing past the small Lake El Bi, it becomes the San Luis River,[4] a name it retains for a short distance until taking on the name Itonomas at its confluence with the Lopez River.

[5] Despite its considerable length, the Itonomas is nominally considered to be a tributary of the shorter Machupo River,[6] which in turn drains into the Iténez River only a short distance further downstream.

Additionally, due to the situation of its headwaters at the eastern edge of the vast Bañados del Izozog, the Itonomas can be considered to be a hydrological continuation of the Parapetí River, which originates in the Bolivian Andes.
