rivers tributary to the St. Lawrence from the north are the Ottawa, St. 
Maurice and Saguenay whilst from the south are the Richelieu, St. Fran- 
cois and Chaudiére, all of which as well as many others, have extensive 
water power resources. There is also a large number of considerable 
rivers flowing towards James, Hudson and Ungava bays. 
The total available power resources of Quebec are estimated at 8,459,- 
000 horse-power under ordinary minimum flow conditions and 13,064,000 
horse-power ordinarily available for six months of the vear. At the

sites ‘included in these totals, installations aggregating about 2,380,000 
horse-power have already been made which, bearing in mind the general 
relationship existing between installation and available resources. repre- 
sents about thirteen per cent of the total available. 
It is not possible in the space available to treat fully the principal 
power rivers of the province. However, a few of the more outstanding 
may be mentioned. The St. Lawrence river between the Ontario boundary 
and Montreal has between two and two and a half million horse-power 
available; the Ottawa river and its Quebec tributaries from 1,000,000 
to 1,600,000 horse-power; the St. Maurice and its tributaries upwards 
of 1,000,000 horse-power and the Saguenay and tributaries from 1,260,000 
to 1,530,000 horse-power. It should be borne in mind that these resources 
will justify an economic installation greatly in excess of the figures given. 
It should also be observed that some of this installation has already taken 
place and is included in the list given in Appendix II, page 126.
