...Dams in Canada
Comparing
Malaysian and
Canadian Experiences
with Dams
|
Canada has had far more extensive experience with
dams than has Malaysia. For this reason, and because it can be
useful to link study of conditions in other countries with more
familiar conditions in Canada, it is appropriate to develop a
basic understanding of this Canadian experience. Over the last
forty years, as this experience has accumulated, attitudes towards
dam projects have also evolved in Canada. By recounting briefly
this My focus will be on changing
attitudes towards dams and rivers in British In focusing on the rivers of British Columbia, two themes will become especially evident. One concerns the relation between the development of rivers, primarily for hydroelectric power production, and the general economic development of a province. The second theme concerns how the use of rivers relates to Canadian politics and economic priorities, and, more generally, to the values and attitudes of Canadians towards their landscape. One can discuss these themes in terms of two seminal events, that mark, roughly, the beginning and end of a period of transformation of attitudes towards rivers in British Columbia, and their development. These events occurred in 1950 and in 1995. In each year, an important decision was made concerning large-scale river development in northwestern BC. In 1950 the decision was made
to construct a massive river diversion and In 1995 a second decision was
made. This decision concerned a proposed In short, therefore, a strong contrast is evident between 1950 and 1995 -- not only in the actual decisions, but in how the decisions were made. How can this contrast be explained? An immediate answer, of course, lies in the facts of the cases. Evidence presented during public debate prior to 1995 demonstrated that the project would likely have significant impacts on valued resources, such as the salmon stocks of the Nechako River. However, for a more complete answer it is necessary to examine the history of water development in British Columbia, and, more generally, the economic and political history of British Columbia itself between the late 1940s and 1995. The Era of Big B.C. dams At that time, several perceptions of the project were evident. On the one hand, within the Canadian business and engineering communities, there was great enthusiasm. Construction created 2400 jobs directly, and many more among the project's suppliers. More generally, the project was seen as an important means of turning B.C. rivers to greater use. Ultimately, the project was a powerful symbol of progress. As one magazine ad of the time enthused:
Others, however, felt less enthusiasm towards the project. Among fishers, there was concern about the potential loss of salmon stocks. The Nechako River was one of the richest salmon tributaries on the Fraser river, supporting many thousands of spawning salmon. When, however, the dam on the Nechako was completed, and the dam was closed to allow the reservoir to fill, river flow dropped to zero between October 1952 and June 1954, followed by only intermittent discharges from June 1955 to January 1957. During this dry period salmon stocks were virtually eliminated. There was also less enthusiasm among those concerned about wildlife and natural areas. The project flooded several river valleys and lakes within Tweedsmuir Provincial Park, the largest provincial park in B.C.. As a result of the project, the boundaries of the park were redrawn, removing 200,000 acres from it. Most especially, there was very
little enthusiasm within several native communities in the region.
The first meeting with natives whose community was located where
the reservoir would eventually be, took place on April 3, 1952.
The issue to be discussed was relocation of the community, and
compensation for those affected. The issue was of some urgency:
the dam had already been built, and five days after the meeting,
the dam was closed, and the reservoir started to fill. A settlement
was reached on April 21, 1952.
The compensation provided to those relocated was inadequate. In 1987 (35 years after the relocation), the federal government accepted this claim; those affected, however, are continuing to seek additional compensation. Overall, however, there was very
little concern evident in official circles about these varied
consequences of the project. This was reflected in the treatment
of those relocated. It was also reflected in the lack of attention
paid to protecting salmon stocks. The federal fisheries department
had recommended some modifications to the project that could
provide some protection to the salmon stocks. However, Alcan
choose not to carry out This pattern of development continued in B.C. for several decades. Between the 1950s and the 1970s a series of dams were constructed across the province. As Figure 3 indicates, the dams were concentrated on two large river systems: the Peace, and the Columbia rivers. This reflected the "two rivers policy" of the provincial government. Projects included:
Overall, by the early 1970s,
a considerable fraction of B.C.'s rivers had been What factors and priorities
did this development reflect? However, these dams were more than simply sources of electricity. They served as well as a key part of the provincial economic strategy. W.A.C. Bennett, premier of B.C. between 1952 and 1972, had as his chief political goal the rapid political and economic development of his province. BC. Hydro was a key part in this, serving as not only an electrical utility, but as an instrument to encourage economic and industrial development. Bennett sought to promote resource development by developing the hydroelectric resources of the Peace and Columbia Rivers (the second and third largest rivers in B.C.). This was not an objective shared by BC Electric, the private provincial electrical utility, which considered other sources of energy to be more cost-effective. Accordingly, Bennett nationalized BC Electric, to create BC Hydro. Its role subsequently became similar to hydro companies in other provinces, including Manitoba and Quebec -- the development of large-scale hydroelectric projects, not only as sources of electricity, but as engines of the provincial economy. Overall, the economic importance
of hydropower was seen as two-fold: the But hydropower was also seen
as a supplier of political power. Bennett viewed it as a means
of asserting B.C.'s political autonomy relative to the rest of
Canada. As a "home-grown" source of economic activity,
it was viewed as lessening the province's dependence on the centres
of political and economic power in eastern Canada. This was an
objective Bennett was willing to achieve at any cost, as reflected,
for example, in the care taken to "fudge" cost estimates
of the Peace River dam, to ensure that it would be Attitudes towards the natural
environment also played a significant part in shaping these views
of hydro development. Rivers were seen primarily as fuel sources
for the provincial economy, wasted unless turned to productive
purposes. One illustration of this can be found in the writings
of Bruce Hutchison, a well-known B.C. journalist. In 1950 he
published The Fraser -- a detailed examination of nearly all
aspects of that most important of all B.C. rivers. After reviewing
the past and present state of river, its discovery,
Hutchinson then went on to describe detailed plans for damming the Fraser. His account is particularly striking because throughout it there runs a hint of regret, at the probable loss of much of the natural quality and beauty of the Fraser, and the elimination of its salmon runs. At the same time, there is a pervasive assumption that dams are inevitable -- that it cannot be questioned that a river must be more valuable as a power source for industry, than as a system supporting millions of salmon:
Such views epitomize, of course, the basic and powerful idea, so pervasive in the 1950s and 1960s as to barely require even debate: that a river that descends off the mountains without turning turbines is a wasted river. Turning rivers to human use becomes, in effect, a moral imperative. In summary, then, the overlapping values and priorities can be identified that led to several decades of intense activity, building dams across several of the largest rivers in BC:
Questioning the value of dams Part of this practical experience
was the accumulated environmental record of dams. The major B.C.
dams were demonstrating a range of environmental impacts. For
example, Arrow Lake (an already existing lake on the Columbia
River), was expanded as a result of the Columbia River Treaty.
Construction of the Keenleyside Dam added about 60 feet to the
height of this lake. Ever since, periodic drawdowns and refilling
of the lake have resulted in elimination of the original shoreline,
and periodic wide flats of dried out mud and dust storms up &
down the lake. As a second example, modification of the flood
Another aspect of experience with hydroelectric projects during the 1970s and 1980s has been that they are often not economically sound. In part, this is because the large annual increases in electricity use experienced in the 1960s were, by the 1970s, only a memory. As a result, hydro development in B.C. slowed down greatly in the 1980s. The next planned hydro development, known as the Site C, downstream of the Bennett Dam on the Peace River, was approved in 1983. However, its construction has never gone ahead, and is now indefinitely postponed. In strictly economic terms, Hydro
projects have often turned out to not be quite the economic boons
once seen. For example, Revelstoke Dam was completed in 1979,
when there was no domestic demand for electricity, and only weak
export markets. As a result, electricity that cost 4.2 cents/kwh
to produce could only be sold for 2.4 cents/kwh. This debacle
generated considerable controversy, and led to an overhaul by
the province of the The social impacts of dams were
also becoming more evident. Numerous The strongest underlying reason
for this anger was the knowledge that these This reaction has also been evident
in Quebec, in the aftermath of the first phase of the James Bay
project. The James Bay and Northern Quebec Agreement of 1975
cleared the way for construction of the James Bay project, and
gave the Cree hunting and fishing rights, control over health,
education and local government, and financial compensation for
relocation and development. The deal was hailed by governments
as a model for future By 1990, therefore, these various issues -- the environmental impacts of hydro power, its economic implications, and its social costs -- had generated a different view of hydro development. One reflection of this was the evolving role of BC Hydro. Over the last 5 years, it has largely transformed its central function, from being primarily a construction company, always looking to the next river to be developed, to a management company, that sees conservation as a more important source of energy than additional hydro dams. It is appropriate now to return
to the Kemano power project, mentioned above. How did this new
view of hydro developments shape the decisions to be made in
the 1990s concerning expansion of this project? In 1979 Alcan
announced that it planned to expand its power production at Kemano
by 50%. It would do this by diverting more of the flow of the
Nechako River. Accordingly, it entered into secret negotiations
with the provincial and After that date, however, debate increased rapidly, and the issue became one of the leading environmental controversies in B.C. during the early 1990s. In particular, there was considerable doubt that salmon stocks could survive such low flows. In 1990, federal Department of Fisheries and Oceans scientists charged that their own department had disregarded the advice of its own scientists, who had said that salmon would not be protected. The immediate outcome of the
controversy was a public review of the Alcan How, then, can this episode be
interpreted? Of course, as noted above, the
Overall, it is evident that the immediate decision made in 1995 concerning Alcan's Kemano expansion project has roots that extend across several decades. This project epitomized economic, environmental, political, and ethical values and priorities prevalent during the 1950s and 1960s, but that, by the 1990s, were being questioned, even rejected. The decision to cancel the expansion project was therefore the product of not only an evaluation of its immediate benefits and costs, but of an evolution of values and priorities in B.C. during the decades since construction of the project's first phase. |
