The only reservoirs on the western division are the Oil creek 

 and Rockville reservoirs, originally constructed to feed the sum- 

 mit level of the Genesee Valley canal, and still retained as sub- 

 sidiary feeders to the Erie canal, their waters being finally dis- 

 charged into the Genesee river and thence taken into the canal 

 through the Genesee river at Rochester. The main characteris- 

 tics of Oil creek and Rockville reservoirs may be obtained from 

 table Xo. 95. 



The sources of water supply for the western division are: 

 Lake Erie, at Buffalo; Tonawanda creek, at Pendleton; Tona- 

 wanda and Oak Orchard creeks, at Medina: Aliens creek, 

 through the prism of the old Genesee Valley canal, from Scotts- 

 ville to Rochester; the Genesee river at Rochester. 1 



By virtue of the geographic position of Xew York, with the 

 Great Lakes on its western boundary and the Atlantic ocean 

 on its eastern, and with the commercial capital of the western 

 continent as its chief city, all discussions of deep waterway 

 projects from the upper Great Lakes to the seaboard are neces- 

 sarily chiefly discussious of the water resources of Xew York. 

 It is proper, therefore, that the several deep waterway projects 

 should be briefly noticed in a report of this character. 



The foregoing statements as to length, water supply, and reservoirs of the 

 Erie canal, while covering only a small amount of the total data, are still 

 as much as can he given at this time. Full information may be obtained 

 by reference either to the annual reports of the State Engineer and Sur- 

 veyor from 1850 to 1903, inclusive, or to those of the Superintendent of 

 Public Works from 1S7S to 1003. inclusive. Previous to 1878 reports of 

 the Canal Commissioners may also be consulted for a large amount of 

 Information.
