64 REPORT OF THE No. 3 



in a manner similar to the posts. In cases where there were no trees and where 

 it appeared Hkely that a post would be moved by ice, no distinguishing mark 

 was left, but all such islands can be easily identified by reference to the plan 

 of the survey. 



At each of the rapids and falls where there is any possibility of future 

 hydro-electric developments, a site was laid out to provide for such develop- 

 ment. These sites are all large enough to control the various water powers 

 and provide ample room for the construction of such dams, flumes, and other 

 structures as may be necessary. The lines around these sites were not cut 

 out on the ground, but are indicated on the plans and the proper position of 

 these lines is marked on the ground by substantial posts in mounds of stone, 

 erected on each of the projected lines a sufficient distance back from the shore 

 to ensure their permanency. These posts are marked with the letters W.P.R. 

 to indicate water power reserve. 



No levels were run at any of these falls as all information regarding the 

 heights of the different falls, flow of water, etc., had already been obtained 

 by the Ontario Hydro Power Commission and by the Dominion Water Power 

 Branch of the Department of Interior, In addition to this a line of precise 

 levels has been run during the past few months down this portion of the English 

 River by the Geodetic Survey Branch of the Department of the Interior, Ottawa. 



A copy of the field plan of my survey showing the location of all monuments 

 planted during the season was sent to the Geodetic Survey Branch last fall, 

 in order that the standard bench marks established by their parties could be 

 tied to the monuments planted by myself wherever possible. 



The English River forms the boundary between the districts of Kenora 

 and Patricia. It is a large stream as is shown by the fact that the discharge as 

 determined by the Ontario Hydro-Electric Power Commission's engineers at 

 Oak Falls, on October 19th, 1915, was found to be 9,358 cubic feet per second. 

 There are several sites suitable for water power development on a large scale, 

 and the large stream flow coupled with the splendid facilities for storage, render 

 the power possibilities of this river of great importance. The Dominion Water 

 Power Branch of the Department of the Interior has collected very complete 

 data regarding the power possibilities of the English River and the reports are 

 available for those who are interested. 



The English River flows from Lac Seul in a general westerly and south- 

 westerly direction. The first falls occur a couple of miles down stream from 

 Lac Seul, where Upper and Lower Ear Falls, which are only about a quarter 

 of a mile apart, drop twelve feet and nineteen feet respectively, giving a com- 

 bined drop of approximately thirty-one feet. From Ear Falls the river continues 

 with gentle current for a distance of about fourteen miles to Camping Lake. 

 This lake is over two miles across and a short distance below the lake the river 

 breaks through a narrow gorge less than a chain across at Manitou Chute, 

 where there is a drop of three and a half feet. A quarter of a mile down stream 

 is situated Manitou Falls, where there is a total drop of twenty-eight and a 

 half feet in a quarter of a mile. The combined head at Manitou Falls including 

 Manitou Chute would be about thirty-two feet, which with the large stream 

 flow of the English River would make a power of great importance. There 

 is a very good site for the construction of a dam at the foot of Manitou Falls. 



Between Manitou Chute and Manitou Falls, Cedar River enters from 

 the southeast. This river was traversed for about two miles up to the first 

 falls. The portion of Cedar River traversed is fairly wide and flows with a 

 sluggish current through a clay country and is bordered for the most part with
