History

The chief historical event associated with Juncal Island is the Battle of Juncal, one of the most important naval battles of the Cisplatine War. Occurring on 8 and 9 February, 1827 between squadrons of the Brazilian Empire and the United Provinces of the Río de la Plata, the result was a complete victory for the United Provinces.

Description

From a geological point of view, the island is a mass of riverine affluvient founded on a precambrian granite core. The coasts are sandy and feature gentle inclines near the channels. The island is low and flat, and can be completely submerged during high water. It has a total length of 4.91 km and a maximum width of 1.95 km.

The western coast of the island is washed with waters from the river Guazú in addition to those of the Uruguay River from the north, while the east receives the cleaner and more oxygenated waters of the Camacho River; in this area a type of fish called a pejerrey (Odontesthes bonariensis) can be found in abundance. As a result, it is a habitual destination for fishing boats.

The vegetation of the island is primarily scrubland, although some trees can be found towards the center.
