Pastaza River

The Pastaza River, also known as the Patate, is a large river that flows through Ecuador and Peru. It is an important tributary of the Marañón River, which is part of the northwestern Amazon Basin in South America. The river begins in the Ecuadorian province of Cotopaxi, near a volcano, and is first called the Patate River.

As it flows south, the Patate River meets the Chambo River near the town of Baños de Agua Santa, and from that point on it is called the Pastaza River. The river passes through beautiful areas, including several waterfalls and rapids that are popular for rafting. One famous waterfall, the Falls of Agoyán, was protected when a dam was built upstream.

After traveling through many regions and forming borders between different areas, the Pastaza River eventually enters Peru and joins the Marañón River near a place called Puerto Industrial.

Tributaries

The Pastaza River has many smaller rivers that flow into it, called tributaries. These help the river move quickly and sometimes cause it to flood.

Along one side of the river, a tributary appears about every 3–4 kilometers for about 50 kilometers. The other side has a few fewer tributaries.

Some of the largest tributaries are the Chambo, Bobonaza, and Huasaga. Others that are also important include the Ambato, the Pindo, and the Puyo.

Economy

The Pastaza River is not used for fishing. It is mostly a path for travel by canoe. The river's water level changes fast and can be hard to predict. It is shallow and has many sandbanks and tree trunks in the water. Sometimes, the river floods during certain times of the year.

Bridges

In Ecuador, there are not many bridges over the Pastaza River. The most important ones are in Tungurahua province. There is a big bridge near where the river starts, just north of Baños, and another bridge made by the Agoyán dam. Other bridges are usually small and made for walking or very small vehicles. During the dry season, you can drive a strong 4x4 truck across the river near the town of Mera.
