. Some of them, the major tributaries of Paraguay and Parana, enabled navigation on a small scale, and smaller boats with limited use in times of drought due to decreasing flow of water flows.

Paraguay river tributaries

Among the subsidiary of the left bank of the Paraguay River are:

The Jejui River

The Jejui River covers an area of approximately 350 km. It receives water from rivers Jejui-mi and the Jejui Guazú, in addition to substantial influx of the Aguaray River. Near its emerging flow together the Curuguaty River and the stream Itanará.

Historically it had strategic importance by the Portuguese, who continuously attempted to control this communication channel to access to the Paraguay River

Navigation

The river maintained in the past a greater flow by the regularity of rain and humidity sustained by its extensive forests. Until the middle of twentieth century it was common to observe in its lower reaches, the transit of boats transporting hardwoods and mate.

In the boom of the mate herb production there was a constant movement of small-size boats coming up ports of Itaba and Ysaú. The first was a major point of embarkation of mate

 latitude, was an active meeting place for traders engaged in the provision of goods for crews of boats and residents of neighboring villages. There workers spent their meager assets after they had worked for long months. There were piles of firewood in the canyons of the river - basic material for the operation of boilers and steam plants - and thousands of rolls of hardwood accumulated waiting to be shipped to ports below.

The loss of coastal mountains filled up the river's banks with wastes and this decreased the depth of its waters. Later, the construction of overland routes produced, moreover, the abandonment of this route as a means of communication.

The Manduvirá River

A similar phenomenon occurred with the Manduvirá River of 212 km long. It is born in the Cordillera de los Altos and moves from east to west. For many years this was the alternative to reach isolated villages like Arroyos y Esteros
