Stave Falls
The Stave Falls Dam and powerhouse are nestled in a
mountainous valley north of the mighty Fraser river,
near Mission. The dam is part of the Stave Falls-Alouette-Ruskin
generating complex.
In the 1890's the 24m (84 ft.) drop to the lower Stave
River at the falls was seen to be a potential source of
water power. Permission to exploit this source was granted
in 1895 to the Stave Lake Electric and Power Co. Ltd.,
through an act of provincial legislation, for the purpose
of generating electricity to use either for electric
lighting, motive power or other work. Then in 1900
Stave Lake Power Co. (est. 1899) obtained the right to
generate power from the Stave River and its tributaries
by grand order of council. Although Stave Lake Power Co.
had a different name than its predecessor the Stave Lake
Electric and Power Co., it's widely believed that they
were one and the same company.
Construction of a logging road and a concrete log sluice
by the Stave Lake Power Company began in 1901. In 1909
assets were taken over by the Western Power Co. and they
immediately applied to use Stave Lake to store water.
Before approval could be given the Dominion and the
Provincial governments had to settle a court battle
to see who had authority to grant water rights on
the Dominion Railway belt.
Work began on the first phase in 1909-10, with the work
consisting of building a dam with a sufficient height
to create a 100 ft. head of water. The powerhouse had to
be able to house two power units consisting of 13,000
horsepower 7,500 kw generators. The power plant and sites
for the switchboard, transformers, transmission lines,
facilities and distribution network had to be chosen
carefully to maximize power generation and to minimize
construction costs. The complex systems including the
reservoirs, dams, powerhouse and transmission facilities
required for hydroelectric development required considerable financial commitment.
Also in 1909 a wagon road was built from Ruskin. In order
to move supplies the wagon road was turned into a railway
connected to the CPR mainline. To this day it holds the
title of the world's shortest railway.
By the end of 1911 a contract was secured to supply power
to Vancouver, New Westminister, Burnaby, Coquitlam, Maple
Ridge, Mission and Bellingham, Washington. Power sales
in 1911-12 were brisk. Smaller customers were supplied
with their own transformers on site, while the bigger
customers had to maintain an electrician and manage the
electrical power supply at its delivery point.
The first phase began producing power on Jan. 1, 1912 with
transmission lines going west of Stave Falls to a receiving
station at Ardley (between New Westminister and Vancouver)
and south to Sumas, Washington. The steel towers of the
transmission line had to be placed with great ingenuity
and special care had to be taken to make sure the wires
were of sufficient height and distance to permit water
navigation of the Pitt River. They were the first to be
used on the west coast, north of San Francisco.
In 1913 a contract with British Columbia Electric
Railway (B.C.E.R.) to provide power over a period of
twenty years was signed. Also in 1913 there were contracts
to improve the dams and extend the plant to make room
for the installation of two new turbine generator units.
Unfortunately the demand for power dropped (also in 1913)
with the beginning of a economic depression and the
second phase of construction ground to a halt when the
war in Europe lead to more economic uncertainty. They
were still committed to the contract with B.C.E.R. when
the company had trouble with money for phase two. The war
also held up one of the two new turbines in Zurich, delaying
its delivery until the end of the war. Labour problems
meant that a third unit did not come on line until 1916.
Western Canada Power became Western Power Co. of Canada
Ltd. in 1916. In 1921 B.C.E.R. gained control of Western
Power and began to develop the combined water power at
Stave Falls, Alouette Lake and Ruskin. B.C.E.R. already
had the rights to the Alouette development including
completion of the first phase and the extension of work
begun by Western Power including a fourth turbine ordered
in 1913 and installed in 1922.
B.C.E.R. also made improvements to the Blind Slough Dam
site, it was their mandate to raise and improve the dams
at Stave Falls. By diverting water from Alouette Lake
through a tunnel to Stave Lake the amount of power that
could be generated at Stave Falls was increased. Work on
the Alouette tunnel was watched closely by B.C.E.R.
employees who created a company sweepstakes for the date
of breakthrough, the prize of $87.00 was won by Miss
E.E. Farmer, a stenographer.
The additional flow from Alouette Lake allowed B.C.E.R.
engineers to add a fifth unit at Stave, this unit
however was not part of the original plan so the unit
had to be squeezed into all available space. The intake
for the new unit was inserted at the eastern end of the
dam with the penstocks being installed over the existing
penstocks on the western end of the dam where the
extension for the fifth unit was built. Engineers
described the intake design as challenging, with the
excavation work for the powerhouse extension being very
painstaking because it was being carried out within 25
ft. of a working generator.
To further increase efficiency the existing generators
were rebuilt and their capacity increased. This meant
that the present switching system at the powerhouse
was obsolete and had to be rebuilt, but there was not
enough room in the powerhouse for the required system.
After considerable debate about where the equipment should
go the final decision was to put it outside of the powerhouse.
In the fall of 1925 B.C. Premier John Oliver turned the
golden key to start up the fifth generating unit. Stave
Falls capacity was trebled and the plant was the single
largest source of power for B.C.E.R. at the time.
The creation of Hayward Lake, with the building of the
Ruskin Dam, completed the last phase of the development
of the hydroelectric potential of the Stave River (until 1997).
Stave Falls Company Town
During construction various buildings were erected around
the powerhouse site to house the workers and their families,
this created the Stave Lake community. The structures
included a freight shed, railway station, store, doctors
office and a machine shop. An estimated that 400 men were
employed in the construction of the railway and work at
the falls. Stave Falls bore the mark of a company town:
B.C.E.R employees were housed by the company; the company
also provided recreational facilities that included a
badminton court, tennis court, dance hall and a lawn
bowling green. The company also employed a gardener
and a carpenter to maintain the site.
The subsequent population of Stave Falls varied,
depending on the amount of work being done in the
construction and logging industries. The company
town gradually declined in the 1950's, and ended
with the creation of B.C. Hydro in 1964.
