When the State government officially
opens the Paradise Dam, on the Burnett River some 80kms southwest
of Bundaberg, on September 1st, it will be just over a week out
from a state election where water and water management have been
major issues.
Last December, when Premier Peter
Beattie officially named it Paradise Dam, it was widely held that
it would be full by the end of the wet season. Perhaps it’s
just as well he’d chosen the name “Paradise” over
the major alternative “Boolgee”, an aboriginal word
meaning “full”, as the dam, despite that earlier optimism,
now holds a mere 15% of its capacity.
Delivered as a result of a major
electoral commitment made during the 2001 elections, Paradise Dam
is the physical embodiment of an electoral promise that didn’t
hold water.
Assuming it eventually fills to
its 300 000 megalitre capacity, the dam, the ninth largest in Queensland,
will impound almost 30 square kilometers and a 45 kilometre length
of the Burnett River and will join the more than 30 dams and weirs
already on the river and its tributaries. While the Burnett’s
catchment is considerable, its rainfall certainly isn’t. On
its tributaries, the Cania and Wiruma Dams to the northwest are
only 6% and 1% full, respectively, while the Bjelke-Petersen Dam
in the South Burnett is at just 3%.
The dam was always a controversial
project as it included some of the best breeding and spawning grounds
for the Queensland Lungfish whose worldwide distribution is restricted
to the Burnett and Mary Rivers in southeast Queensland.
World-renowned lungfish expert Professor
Jean Joss of Macquarie University says that while adult lungfish
live successfully in dams, they require “shallow, slow-flowing,
densely-vegetated riffles as spawning and nursery habitat.”
These features are characteristic of both the Burnett and Mary Rivers
but it is precisely these features that are lost by permanent flooding
resulting from the construction of a dam.
As well as the lungfish the Burnett
is also home to an as yet unnamed species of Elseya turtle. Both
turtle and lungfish are understood to be quite long-lived. One lungfish
living in captivity in USA was taken there as an adult 80 years
ago. Because of their long life span as well as both their lengthy
breeding life and time taken to reach maturity, there is a well-founded
anxiety that any drop in reproductive rates won’t be readily
detected.
Despite all this, the state government
has repeatedly claimed that “Paradise Dam has raised the bar
for environmental construction of dams and land rehabilitation.”
In fact Premier Beattie’s release on the occasion of the official
naming went so far as to declare “Paradise Regained For The
Environment With Dam Construction”.
Much faith is being place in a specially constructed fish elevator
that, it is hoped, will facilitate upstream movement of fish which
are lifted in a cage from a pool at the base of the wall up and
into the dam itself. There is considerable doubt among scientists
that the elevator will be effective, but even if it is, Prof Joss
says it will “simply take lungfish from one non-breeding area
to another”
But the project has come in for
criticism for more than environmental reasons. It was never highly
popular among irrigators and downstream communities, ranking only
29th out of 30 in original preference. One reason for the reluctance
was the high price anticipated to be charged for the irrigation
water.
The dam’s expected annual
yield is 124,000 megalitres for agricultural use and another 20,000
megalitres for urban and industrial use. These yields together account
for almost half the volume of the dam and when an environmental
flow allocation is also factored in, it’s plain that the dam
would need to hold a lot more water than it does at present if it
is to fulfill them.
There is a delicate balancing act
between setting a unit price for water that would recoup the cost
of the dam plus the ongoing operational costs and setting one that
irrigators are prepared to pay.
Too high and it will remain a white
elephant, too low and it will require ongoing government subsidies.
Indeed this was the overriding factor
in the view of a recent international study on dams by the WWF.
It singled out Paradise Dam as one of six internationally that it
considered to have failed to meet the criteria of the World Commission
on Dams.
Its report was critical of the lack
of transparency about stated economic benefits and concluded that
“based on the available information there are serious concerns
about the economic viability of the dam as much of it depends on
the expansion of the sugar industry. However, the sugar industry
has not been profitable and it is likely that producers will be
unwilling to pay the high water prices that are needed to achieve
full recovery of the dam’s costs. As a result, it is likely
that the dam will require subsidies indefinitely.”
Ever on the lookout for good media
opportunities, it’s significant that Premier Beattie won’t
be performing the opening ceremony himself, despite the fact that
he’s repeatedly staked his environmental credibility on Paradise
Dam.
In Parliament, on June 6th, he
claimed the fish elevator had been successfully operational for
several months and a turtle hatchery established. His assertion
that “at Paradise Dam we planted over 100,000 trees to replace
those affected by inundation” has been seriously questioned
by conservationists, wondering how the loss of 45 kilometres of
diverse riparian vegetation can be so readily offset by fresh tree
plantings.
Yet he’s apparently undeterred
by any criticisms, including those of a growing number of international
scientists, nor by the considerable and widespread groundswell of
opposition to the Traveston dam proposal. In fact, he’s continued
to hold Paradise aloft as a model for Traveston, an even more ambitious
folly poised to flood more than twice the area, on the world’s
only other lungfish river, the Mary.
All this will be weighing on the
mind of outgoing State Development Minister Tom Barton as he performs
the opening on September 1st.
As he looks out over the earthworks
will he see a fractionally filled dam or a drowned river?
Will it cross his mind that the assessment that this dam “
has the potential to increase net wealth in the region by up to
$800 million a year and create more than 7000 new jobs” may
hold as little water as the dam itself?
As he ponders his last week in politics, will his enduring view
of Paradise be as a feather in the cap or an albatross around the
neck?.
