ZONES OF THE RIVER URUGUAY 



The river Uruguay has been divided into the follo- 

 wing zones, or sections, which correspond to differences 

 of the regime and distinct conditions of navigability. 



1st, lower Uruguay: from its mouth in the River Plate 

 situated above Nueva Palmira between Carbon Point and 

 Chaparro Point, to Concepcion del Uruguay. Its exten- 

 sion is about 180 kilometers ( Sheets 5, 6, and 7 ). 



2nd middle Uruguay : Prom Concepcion del Uruguay 

 to Salto ChieOj situated immediately above Concordia, its 

 extension is about 160 kilometers (Sheets 2,3 and 4). 



3rd upper Uruguay: From Salto Chico up river, [ts 

 extension is 425 kilometers ( Sheet 1 ).

The Lower Uruguay has again been subdivided into 

 two parts, which differ greatly between each other : the 

 first goes from its mouth to the mouth of tiie river Gua- 

 leguaychii, and the second from the mouth of the river 

 Gualeguaychii to Concepcion del Uruguay.
