FISHERIES, GAME AND FORESTS. 387 



The conditions on Mohawk River may also be specially mentioned. The main 

 tributaries of this stream from the north are East and West Canada Creeks, which 

 both have large natural lake storage with a consequent low water flow of at least 0.3 

 of a cubic foot per second per square mile. The main tributary from the South is 

 Schoharie Creek, which has no natural lake storage and which runs down in dry 

 weather to less than o. 1 of a cubic foot per second per square mile. In both cases the 

 surface slopes are steep and a considerable part of the variation in low water flow is 

 due to differences in natural storage conditions. However, the fact that Schoharie 

 Creek catchment area is deforested, while Canada creeks' areas are still largely in 

 forest, as well as differences in surface geology, may be taken into account. Never- 

 theless, when all proper allowances of this sort are made, it still remains true that 

 the differences in surface storage are contributing causes to the differences in value 

 of these creeks in their natural state as mill streams. 



WATER STORAGE SYSTEMS FOR THE CONSERVATION OF WATER-POWER 

 COMMON IN THE EASTERN UNITED STATES. 



Storage projects with reference to conserving the flood water of the winter and 

 spring season in order to foster water-power interests have probably been as extensively 

 inaugurated in the United States as anywhere. In foreign countries many vast 

 reservings have been created for storing water for irrigation, and for checking floods 

 in mountain streams, but aside from a few cases in France, Belgium and Germany the 

 vast foreign constructions of this character have not generally been for the benefit of 

 manufacturing. In Massachusetts, Connecticut, Maine and New Hampshire, however, 

 under the fostering care of rational Mill Acts, reservoirs for water-power purposes 

 alone have been very extensively constructed. Especially is this true in Massachusetts 

 and Connecticut, where practically every stream has its storage reservoir, with the 

 result that the mill streams of those two States may be estimated to be yielding to-day 

 anywhere from 200 to 300 per cent, more power than they could be made to yield if 

 left in their natural unregulated state. Possibly the percentage of increase is 

 considerably higher than this, but in the absence of detai 1 ed statistics it is desired to 

 state it conservatively. There can be no question but that the increase is at least as 

 great as 200 per cent. 



WATER STORAGE IN NEW YORK. 



Even Ln the State of New York, where, as shown in the foregoing, we are, 

 considering our natural advantages, somewhat backward, still, from another point of 

 view, we have accomplished a good deal. The reservoirs constructed under the special
