ing a head of 210 feet. The length of dam required for this head would be nearly 

 one thousand feet. A proposed dam is indicated about one mile below head of 

 Canyon, creating a head of 150 feet by flooding water back to foot of Burnt- 

 wood Chutes, such dam would have a crest length of about three hundred feet. 

 There appear to be several alternative ways of making this development, and it

requires much detail study. The watershed area at this point is about 8,575 

 square miles. The flow of the river at the Abitibi Paper Company's develop- 

 ment at Iroquois Falls is known and the watershed area at that point is also 

 known, and the additional flow for the total area can be computed, thus giving 

 total flow with fair accuracy.

seven feet. There is a good dam location at the foot, where the width is about 

 four chains, including a rocky island. A dam to develop the full head of the 

 Otters would be required to be a considerable- length, but would-be founded on 

 exposed rock for the greater part. Depth of overburden might be considerable 

 at^tho extreme ends. The river widens out considerably at the foot of thejapids.
