CATSKILL AQUEDUCT 



LINES SURVEYED FOR LOCATION 

 TO JANUARY I. 1907 



Outline Map showing Alternative Lines studied as Possible Crossings 



of the Hudson River. 



New York City will be eighteen miles 

 long. The Ashokan reservoir is at a 

 sufficient elevation to permit water to 

 flow down to the Hill View reservoir, 

 but a number of valleys and streams 

 must be crossed, the most striking, 

 from the point of view of the outsider 

 at least, being the gorge of the Hudson 

 Eiver. More than two hundred borings 

 were made at various points, and it 

 "was finally decided to construct the 

 aqueduct under the Hudson between 

 Storm King and Breakneck mountains 

 at the north entrance to the Highlands. 

 It would be possible to bring the 

 water in iron pipes through the mud 



and silt, as has been done in the case 

 of. the Pennsylvania Railway in New 

 York City, but a tunnel through the 

 rock will give great strength and per- 

 manence. The accompanying illustra- 

 tion shows the borings which have been 

 made at Storm King, revealing the 

 extraordinary depth of the Hudson 

 gorge. It has been known through the 

 maps of the U. S. Coast and Geodetic 

 Survey that the Hudson Eiver is con- 

 tinued by a submerged gorge more a 

 hundred miles across the continental 

 shelf to the deep sea. This gorge at 

 its deepest part is 3,800 feet in depth, 

 and must apparently have been formed
