Bar of «Pepeaji>. 



where over a considerable distance great sand hanks aiv 



Diet with ( Sheet / ). 



The deep channels terminates on the West side of the 

 Boca Chica» island and the navigator has to take the 

 smaller arm, which follows the East coast, which is formed 

 by bluffs. 



The depth of this channel varies from 3 to 5 meters and 

 the maximum width is some 50 meters, for which reason 3 

 buoys must be placed on the East bank. 



Past the North point of the «Pepeaji» island there exists shoai of cp ep eaji>. 

 on the Oriental shore a shoal, which protrudes some 80 nits 

 in the river, and which is indicated by a buoy, which has 

 been placed by this Commission. 



A little below the «Pepeaji» creek exists a shallow place 

 of sand and gravel, which carries the same name and where 

 the depth is only 5 feet at the zero of the gauge (Sheet H). 



In order to eliminate the obstacles which this part of 

 the river presents, several directions have been indicated in 

 the corresponding plan, but the direction corresponding to 

 the smallest cube to be dredged and which maintenance 

 will be the easiest, is, that actually followed by navigation, 

 winch also has the advantage that it can be marked by a 

 line of beacons on both shores, and four buoys. The cube 

 to be dredged in this bar is 100.000 M 3 . 



Above the « Pepeaji » bar the channel occupies the whole 

 widtJi of the river and is of great depth till the «Cancha 

 Seca » is reached which is a shallow placed formed by the 

 sand, which during the great floods of water, is brought 

 down from the sandy bottom of the Merlo creek and which 

 is dropped again when the water of this creek loses its 

 speed on entering the river ( Sheet G). 



There are two channels for navigation, one in the middle 

 of the river and the other near the Argentine coast. 



In the first channel there are 22.000 M 3 to be dredged 

 and it can be marked with two beacons in line on the Ar- 

 gentine shore and four buoys. 



The second channel requires an excavation of only '1000 

 M 3 of heavy gravel which is found above the arroyo «Pal- 

 niar », but at this place, as well as above the « Spina ^> 

 creek there are shoals near the shore, these protude about
