GEOLOGY OF THE NEW YORK CITY AQUEDUCT 



II 



The Catskill supply will furnish over 500,000,000 gallons of 

 water daily and was estimated to cost $161,857,000. That is, the 

 additional supplies from the Catskills as planned will, when com- 

 pleted, be sufficient for the increasing demands of the growing city, 

 for the next 35 years. And some of it may be badly needed long 

 before it can possibly be delivered. 



Parts of the Catskill system^ 



The chief sources within the Catskills now included in the plans 

 of the board are: 



1 Esopus creek, to be taken at a point near Olive Bridge. 



2 Rondout creek, to be taken at a point near Napanoch. 



3 Three small streams tributary to the Rondout. 



4 Schoharie creek, to be taken at a point near Prattsville. 



5 Catskill creek, to be taken at a point about i mile northeast of 

 Durham. 



6 Six small streams tributary to the aqueduct between Catskill 

 creek and Ashokan reservoir. 



The comparative areas of watershed and their daily capacity are 

 estimated- by the corps of engineers as follows :

^ The subdivisions and proposed locations given here are taken chiefly 

 from the Report of the Board of Water Supply of the City of New York 

 to the Board of Estimate and Apportionment, October 9, 1905. 



2 Estimates are much more complete for the Esopus, which it is planned 

 to develop first, than for any other streams ; and it must be understood 

 that the figures are subject to revision dependent upon modifications of 

 original plans to meet the conditions that develop upon more elaborate 

 investigation. 



^ Preparations are to be made for storage of 120,000,000.000 gallons of 

 water on the Esopus, but a part of this capacity is intended to accommodate 

 supplies drawn from other sources than Esopus creek itself.
