The objective of the International Fisheries Commission Was to arrest the serious decline of the halibut fishery and to restore the halibut grounds to the maximum of production. Restoration is being rapidly accomplished, results being particularly reflected in the increase” in the Canadian landings, though this may be accounted for in part by the focal position of Prince Rupert with respect to the fishing grounds, the excellent facilities established there for the quick-freezing and storage of halibut, and the fast rail movement of shipments from this port to the prime- consuming points in the East. The International Pacific Salmon Fisheries Commission had as its object the restoration of the sockeye (red) salmon © fishery in and tributary to the Fraser River, once the Coast’s greatest fishery, and which, as a result of physical obstacles to the free passage of spawning fish, had declined to a fraction of its earlier runs. Under the Commission’s broad powers and financed by a grant of $2,000,000 furnished by the two Governments, corrective measures have been successfully put in effect, and the Fraser is on its way to restoration as the prime. salmon river of the Pacific Coast. Regulation and control of fisheries are among the most dificult functions with which an administrative or con trolling body can be faced. When complicated by inter- national considerations, the problems arising in the past have often defied solution and have led to friction, sabotage, and sometimes to the creation of international “incidents”. While much has yet to be done, the results of the work of these two international commissions in the North Pacific indicate that an important formula for international co- operation has been found and a milestone passed in the economic history of international relations. In the great basin of the Mackenzie River and its tribu- taries, from northern Alberta through the Northwest plain to the Arctic Ocean, there are vast lake and river systems capable, in controlled conditions, of producing an important sustained yield of fresh-water fish. Much of this area is remote from the great consuming centres and the problem of transportation is, as yet, too great to admit of extensive exploitation, except in those more accessible waters such as Great Slave Lake, Lake Athabaska, Lesser Slave Lake, and other northern Alberta lakes that have been fished commercially for some years. The principal present use for fish in the far northern areas, outside domestic food needs, is in the feeding of dogs, on which the country depends for winter transporta- tion by land. Except for the developed or partially developed com- mercial waters mentioned above, consideration of the potentialities of the vast northern interior has been con- fined to the Mackenzie River and Great Bear Lake, with which might be included Great Slave Lake, although the latter has of late developed a considerable fishery. It is impossible, with present knowledge, to assess the potential [20] of Great Bear Lake. However, the low organic pro- ductivity of the waters, a rather spotty history of failures of runs, and the small dependent Indian population suggests the probability that Great Bear Lake may be unable to support any substantial commercial fishery. Such a conclusion, however, on the thin evidence available, would be dangerous. The fact is that until a great deal more work is done on these and other far northern waters, including the deep sea waters of the Arctic Ocean, little can be said about their fish resources. This is one of the investigations that should be carried forward more vigorously. Water-Power Resources The water-power resources of the North Pacific Region are great in extent. From information presently available, they are estimated to total almost 4,700,000 horse-power under conditions of ordinary minimum flow or nearly 8,500,000 horse-power ordinarily available for six months of the year. In such a vast area, however, with widely varying topographical and meteorological conditions, some sections are more favourably situated than others in regard to opportunities for water-power development. In the section of this report dealing with the water-power resources of the Region, the subject is discussed in considerable detail under the four main drainage systems—Coastal Drainage, Upper Fraser River Drainage, Mackenzie River and Arctic Drainage, and Yukon River Drainage—and it will be found that power possibilities, both great and small, are more widely distributed in the Coastal and Upper Fraser River drainages than in the Mackenzie and Yukon Rivers systems. Estimates of the resources of the four principal drainages, based on existing data, are sum- marized hereunder. Estimated H.P.

These are chiefly in the coastal area of British Columbia for use in connection with the pulp and paper and mining industries, and to supply the needs of Prince Rupert. In the Yukon, a single development of 15,000 horse-power serves the demands of a placer gold-dredging plant and supplies the
