THE MIDDLE URUGUAY 



The zone of the river, which has been ealled the Middle state of naviga- 

 bility. 

 Uruguay begins at Concepcion del Uruguay, this part being 



the terminal port for Ocean navigation and because a 



little higher up river at the Oriental Port of Paysandu the 



transhipments of the vessels begin, which continues t ill 



Concordia.

15 feet, it was projected to give the same depth to the San 

 Francisco bar, which obstaculises the access to the Port 

 of Colon, but afterwards as it appeared that those works of 

 canalization had not given a satisfactory result for want of 

 maintenance and buoying, this idea was given up, it being 

 decided to provide only a depth of 2,74m ( 9 feet ) for this 

 bar, which decision was approved by Superior decree of the 

 15th. of June 1901. 



The projected depth for this entire zone has therefore 

 been fixed at 2,74 meters ( 9 feet ) by a width of 50 me- 

 ters (the «San Francisco » bar excepted, which will have 

 a width of 100 meters ) which wall be sufficient for the 

 proposed purpose as a glance at the curves of the levels of 

 the water at Concepcion del Uruguay, Nueva Escocia and 

 Concordia will show. It must here be observed that in all 

 the plans and calculated quantities a depth of 3 meters has 

 been adopted in order to keep into account the imperfect 

 class of work done by the dredgers, so as to obtain practi- 

 cally depths of 9 feet,
