canalized river and 8^ miles of excavated canal. The estimated cost 

 is $25,000,000, and it is hoped that it will be completed in 1921. 



On the United States side of the river the Hydraulic Power and 

 Manufacturing Co., Niagara Falls Power Co., and the Cliff Distribut- 

 ing Co. have been consolidated. The consolidated company has a 

 present capacity of 370,000 h.p., and an extension, to be completed 

 this year, will contain three units of 33,000 h.p. each, an addition..! 

 capacity of 100,000 h.p. 



„. ^,, The most important water conservation work now 



Big Eddy ■ • r^ • • i t • i 



Conservation under construction m Ontario is the International 



^^™ Nickel Co.'s Big Eddy conservation dam on the 



Spanish river, in Algoraa district. This dam will raise the level 

 of the river 100 feet, and will create a lake with an area of 15 

 square miles. Combined with the storage in the upper third of the 

 Spanish River watershed, it will increase the minimum flow to over 

 1,800 cubic feet per second, or almost three times the natural low- 

 water flow, namely, 675 cubic feet per second. It will also create a 

 power site, where 15,000 h.p. can be continuously developed. 



The engineer who designed this work, Mr. Henry Holgate, 

 states that: 



"When this work is complete, the waters of the Spanish river 

 above the township of Hyman will be conserved to their full extent, 

 and this will be one of the most complete systems of water conserva- 

 tion in Canada. 



"Conserving water, and regulating flow on our streams, is one 

 of the most important subjects we have before us, and merits the 

 co-operation and assistance of the Government, as it should be a 

 cardinal principle in power development that the full efficiency 

 of the water in the watershed be made use of, and this cannot be 

 done unless carefully considered systems of storage are provided, 

 so as to equalize the flow as nearly as possible throughout all seasons 

 of the year." 



St. Lawrence River 



Private Last year, the St. Lawrence River Power Co., a sub- 



Development in sidiary of the Aluminum Company of America, 

 the St. Lawrence constructed extensive works in the bed of the St. 

 Lawrence river, although such action was in defiance of the terms oi 

 the Ashburton Treaty. This action was taken under permit from the 

 United States War Department, but without obtaining the necessary 

 consent from the Government of Canada. Subsequently, the com- 

 pany applied to the International Joint Commission for authority 

 to erect — as an essential part of these structures — a submerged weir 

 in the South Sault channel of the St. Lawrence, a short distance 

 below the works above referred to, and asked for immediate con- 

 sideration of the application as a ' war measure.'
