Precipitation for the most part is heavy on the Coastal
slope, reaching as much as 200 inches per annum in some
parts. Asa result, streams havea high-rate of run-off.

Discharge records have been kept on the following
streams: Sandell River near Wadhams, August, 1923, to
March, 1932, mean annual flow 471 c.f.s., minimum 16 c.f.s.,
maximum 3,550 c.f.s.; Wannock River near River's Inlet
(Drainage area 1,600 sq. mi.) October, 1927, to September,
1934, mean annual flow 12,100 c.f.s., minimum 1,800 c.f.s.,
maximum 75,300 c.f.s.; Bella Coola River at Hagensborg
(Drainage area 1,650 sq. mi.) December, 1928, to January,
1930, at mouth of river and from January, 1930, to March,
1932, at Hagensborg 12 miles from mouth; mean annual
flow 5,040 c.f.s., minimum 821 c.f.s., maximum 19,800 c.f.s.:
Dean River near Ocean Falls, August, 1923, to March,
1932; mean annual flow 4,790 c.f.s., minimum 590 c.f.s.,
maximum 30,000 c.f.s.; Nascall River near Ocean Falls,
March to September, 1924, April to October, 1925, Febru-
ary, 1926, to September, 1932; mean annual flow 2,270
c.f.s., minimum 227 c.f.s., maximum 27,800 c.f.s.; Stafford
River near Roy (Drainage area 70 sq. mi.) August, 1921,
to November, 1931; mean annual flow, 1,110 c.f.s., minimum
90 c.f.s., maximum 8,910 c.f.s.; Homathko River near Tatla
Lake (Drainage area 250 sq. mi.) May, 1930, to March,
1932; mean annual flow 280 c.f.s., minimum 36 c.fs.,
maximum 897 c.f.s.

Power Resources.—The outstanding development is that
of Pacific Mills, Limited, on Link River at Ocean Falls,
with an installed capacity of 26,850 horse-power. Power
is used to supply the Company’s pulp and paper mill and
the community of Ocean Falls. British Columbia Pulp
and Paper Company, Limited, has a development of 1,750
horse-power on Swanson Creek, and Princess Royal Gold
Mines has developed 1,200 horse-power at Cougar Lake.

Undeveloped water powers on the part of the Coastal
Drainage south of the Skeena River are estimated to total
440,000 horse-power at ordinary minimum flow, or 816,000
horse-power at ordinary six months flow. The sites of
1,000 horse-power or more, which are shown on the attached
list, are too numerous to describe in detail, but it will be
noted from the list and also from the attached map that
the sites are well distributed throughout the area, with
capacities ranging from 1,000 horse-power to 147,000 horse-
power. The most notable resources are those of the
Homathko River which, at five sites, total 136,960 horse-
power at ordinary minimum flow or 385,390 horse-power
at ordinary six months flow. Other rivers with quite
substantial possibilities are the Dean, Nascall, Sandell
Klinaklini, and Stafford, and Mosley Creek.

Power Markets.—The major market at present in the
Coastal Drainage is in connection with the pulp and paper
industry. The development of industries based on forest
resources offers possibilities for future power markets.
All power sites in the area are close to tidewater and are

of interest therefore in the development of industries in

Queen Charlotte Islands Streams

Queen Charlotte Islands are formed by the unsub-
merged portions of the most westerly of the mountain
ranges of British Columbia. They have a total area of about
4,000 square miles, and the topography is rugged, with
several summits of more than 4,000 feet. Rivers are short
and their catchment basins relatively small, but precipitation
is heavy and river gradients are steep.

Power Resources.—No power developments have been
undertaken on Queen Charlotte Islands, but undeveloped
resources are indicated on five streams totalling some
11,830 horse-power at ordinary minimum flow, or 37,900
horsepower at ordinary six months flow. Ain River
and Lignite Creek offer the greatest possibilities, with
lesser resources on Honna, Naden, and Yakoun Rivers.

Power Markets.—Any market for power would depend
upon the development of the mineral, forest, or fishing
resources of the islands.

Upper Fraser River DRAINAGE

The North Pacific Region embraces the upper part of
the Fraser River Drainage, or that part which lies above its
junction with the Chilcotin River, including the drainage
of the Chilcotin; a total area of 53,300 square miles.

The upper Fraser system drains the west slope of the
Continental Divide and the eastern slope of the Coast
Range, together with the great central plateau which lies
south of latitude 54 between the Coast Range to the west
and the Rockies to the east, and extends a narrow arm as
far north as the 56th parallel between the Peace and Skeena
systems.

From its source in Fraser Pass, the river flows in a
northwesterly direction through a steep and narrow canyon
for about 75 miles to Téte Jaune Cache, where it reaches
the bottom of the intermontane valley. It follows this
valley inthe same general direction at a navigable grade
for 150 miles to a point a few miles north of latitude 54,
where it makes an abrupt turn, and at Prince George,
20 miles farther down, it is flowing almost due south.
Here it is joined by the Nechako, which drains an extensive
system of lakes to the west and northwest. About 70
miles south at Quesnel, the river is joined by the Quesnel
River, which drains a system of lakes lying between the
main channel of the Fraser and its headwaters. At Quesnel,
the river begins to cut an ever-deepening gorge through
the plateau. About 100 miles farther south, it is joined
by the Chilcotin, a tributary from the west.

The water supply of the upper Fraser watershed is
largely received from mountainous territory where pre-

cipitation is relatively high. In the central plateau region,
