The Itonomas River is a river of Bolivia that flows through the departments of Santa Cruz and Beni. It is a part of the Amazon River basin.
Originating near Concepción Lake at the confluence of the intermittent Quimome and Santa Maria Rivers as the San Julián River, [2] the river flows northwards until it becomes the San Pablo River near the city of Ascensión de Guarayos, [3] after which point it forms part of the border between the Beni and Santa Cruz Departments. 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.
Over its course it receives tributaries such as the Quizer River.
The Pastaza River also known as the Patate, flowing in Ecuador and Peru is a large tributary to the Marañón River in the northwestern Amazon Basin of South America.

The population density is 11.36 inhabitants per square kilometer, and the overall life expectancy in Bolivia at birth is 68.2 years. The population has steadily risen from the late 1800s to the present time. The natural growth rate of the population is positive, which has been a continuing trend since the 1950s; in 2012, Bolivia's birth rate continued to be higher than the death rate. Bolivia is in the third stage of demographic transition. In terms of age structure, the population is dominated by the 15–64 segment. The median age of the population is 23.1, and the gender ratio of the total population is 0.99 males per female.
