1) St Lawrence system, which includes all waters draining to 

 Lakes Erie and Ontario, and Niagara and St Lawrence rivers. 



2) Champlain system, including all streams in the State tribu- 

 tary to Lakes Champlain and George. The Champlain system is 

 in reality a subdivision of the St Lawrence, but made separate 

 here merely for convenience in discussing the river systems of the 

 State. 



3) Hudson river system, including all streams tributary to the 

 Hudson and its main branch, the Mohawk. 



4) Allegheny river system. 



5) Susquehanna river system. 



6) Delaware river system. 



7) The streams of Long Island tributary to Long Island sound 

 and the Atlantic ocean. 



The Ten Mile river, one of the headwaters of the Housatonic 

 river in Connecticut, flows out of the State to the east, while the 

 headwaters of Ramapo river, in Rockland county, flow from New 

 York into New Jersey. These latter are of possible future im- 

 portance by reason of the necessity of water for the supply either 

 of Greater New York or, in the case of Ramapo river, also for the 

 municipalities of northern New Jersey. Chateaugay river and 

 tributaries of the St Lawrence also flow northward into the 

 Dominion of Canada. 



St Lawrence River System 



This group embraces the streams tributary to Lake Erie, 

 Niagara river, Lake Ontario and St Lawrence river. On the 

 extreme southwest, in Chautauqua county, the watershed line 

 approaches within a few miles of Lake Erie, but at an elevation 

 of several hundred feet above, and as a consequence the streams 

 are short and rapid. A small amount of power is developed on 

 Chautauqua creek at Westfield, and on Oanadaway creek near 

 Fredonia. Cattaraugus, Buffalo, Tonawanda and Oak Orchard 

 creeks are tributaries of Lakes Erie and Ontario and Niagara 

 river in western New York. Buffalo creek is important as form- 

 ing a large portion of Buffalo harbor at its mouth. Several of
