MANITOBA'S CONCERNS
GARRISON PROJECTS
and
DEVILS LAKE OUTLET
Background
Water resources within the Manitoba portion of the Hudson Bay drainage basin are extremely valuable. More than one million Manitobans live in the basin, with approximately 100,000 relying directly on the Red River, Souris River, and Assiniboine River as sources of drinking water. Lake Winnipeg, the 10th largest freshwater lake in the world, supports a commercial fishery with a direct, landed value estimated to be over $15,000,000 (Canadian) annually to the economies of Manitoba and Canada each year. About 800 commercial fishing licences are issued to fishers on Lake Winnipeg, many of these to First Nations peoples. In many cases, fishing is their major source of income. Sport anglers spend another $10 to $15 million (Canadian) annually in this region. The Red River is the single most important sport fishing destination in Manitoba and accounts for nearly 20 % of the total value of this $80 million (Canadian) industry to Manitoba’s economy. In addition, there is an important bait fish harvest in the Red River and the south basin of Lake Winnipeg that returns about $200,000 (Canadian) annually to licenced fishers.
The Boundary Waters Treaty of 1909 between Canada and the
United States stipulates that: "waters flowing across the boundary
shall not be polluted on either side to the injury of health or property on the
other side." The Treaty established the International Joint
Commission to assist governments in finding solutions to water problems and to
try to prevent or resolve disputes.
The issue of biota transfer has become a major concern throughout North America,
in part due to the major economic and environmental impacts associated with
invasive species such as the zebra mussel. This issue is recognized as one of
the most formidable environmental challenges facing governments in North
America. An Executive Order on Invasive Species was issued by the President of
the United States in early 1999, highlighting the serious nature of the issue
and providing direction for preventive and coordinated actions. In Canada, many
jurisdictions (including Manitoba) have developed either policies or legislation
that oppose interbasin transfers because of their potential for severe
environmental damage. Both the United States and Canada are working
cooperatively in many areas to control invasive species through ballast water
programs, sharing of scientific information, regional cooperation to implement
the US Aquatic Nuisance Species Act, plus others.
The Missouri (Mississippi) and Hudson Bay drainage basins, the two largest in
North America, have been separated for about 10,000 years since the last
glaciation. Their aquatic ecosystems have developed separately, with numerous
organisms, both plant and animal, existing in one or the other basin but not
both. For example, zebra mussels have already invaded the Missouri River system
but are not present in the Hudson Bay system. The Devils Lake watershed has been
isolated from the Red River/Hudson Bay drainage system for hundreds of years.
Non-native fish species have been stocked in the lake in the recent past.
It is Manitoba's position that the new Garrison Diversion concept authorized by
the Dakota Water Resources Act of 2000 and construction of the proposed outlet
to Devils Lake, would:
Garrison - Dakota Water Resources Act of 2000
The Dakota Water Resources Act of 2000 replaced the Garrison Diversion
Reformulation Act of 1986, an Act that represented a delicate compromise between
US stakeholders and included consideration of previous International Joint
Commission work on the potential problems associated with diverting water from
the Missouri to the Hudson Bay drainage basin. The Dakota Water Resources Act
now makes it easier to move water from the Missouri to the Hudson Bay drainage
basin.
The Dakota Water Resources Act:
Reasons that led to the recommendation of the International
Joint Commission are as valid today as they were in 1977 -- the enormous threat
recognized by the International Joint Commission has been realized with the
introduction of, for example, the zebra mussel to the Great Lakes, Mississippi,
Missouri, and other major basins.
Northwest Area Water Supply Project
The Northwest Area Water Supply Project (NAWS) is a proposal to transfer
pre-treated Missouri River water by pipeline to Minot. The Missouri River water
will then receive further treatment and be distributed to a number of
communities in the Hudson Bay basin in western North Dakota.
The NAWS project was authorized by the Garrison Reformulation Act of 1986 and
again by the Dakota Water Resources Act of 2000.
The U.S. Bureau of Reclamation prepared an Environmental Assessment under the
National Environmental Policy Act (NEPA) of the NAWS project. In early June
2001, the U.S. State Department formally handed over to Canada the NAWS Final
Environmental Assessment (EA) and the Finding of No Significant Impact (FONSI).
In mid-August, 2001, Canada and Manitoba filed an administrative appeal with the
Bureau objecting to its conclusion that impacts were either insignificant or
could be mitigated. The basis of the appeal was that under NEPA, a comprehensive
Environmental Impact Statement (EIS) should have been prepared rather than the
cursory Environmental Assessment (EA). It was Canada’s and Manitoba’s
opinion based upon legal requirements and precedents, normal procedure, and
significance of impacts that the more comprehensive EIS should have been
undertaken.
The appeal presented legal arguments, identified normal
procedural matters that were not followed, and identified errors of omission and
judgement that were made that under-represented the risk to Manitoba waters
during the lifetime of the project.
During the appeal, Canada and Manitoba raised significant issues with respect to
NAWS project design, the level of pre-treatment, leakage from the pipeline, the
probability of line failure, and the degree to which the project increased the
risk of biota transfer. For these reasons, Canada and Manitoba requested that
the FONSI be withdrawn and that a more detailed EIS be prepared in accordance
with NEPA.
Failure of the NAWS project, with subsequent release of invasive species into
the Hudson Bay drainage basin, has enormous consequences for Canada.
As a result of this appeal, the Bureau issued a revised FONSI in early
September, 2001 that addressed several process issues. However, the Bureau
rejected the majority of Canada’s and Manitoba’s appeal and did not address
any of the scientific arguments made during the appeal. Manitoba continues to
take the position that a full EIS will reveal significant risks to Canadian
waters and that no project should proceed without a full EIS that conclusively
demonstrates compliance with the Boundary Waters treaty.
Red River Valley Water Supply Study
The Dakota Water Resources Act of 2000 calls for a study of long-term
water needs for eastern North Dakota including identification of alternatives to
meet those needs. The Act requires that at least one of the alternatives include
the interbasin transfer of water from the Missouri River. The Bureau, in
partnership with the North Dakota State Water Commission and the Garrison
Diversion Conservancy District, has launched the Red River Valley Water Supply
Study.
Although Manitoba and Canada are informally participating on the Study’s
Technical Team, there are significant concerns regarding the objectivity and
comprehensiveness of the proposed study since the two strongest proponents of
Garrison diversion project comprise two of the three agencies on the Study
Management Team. It is also feared that the inadequate water treatment
identified for the NAWS project will be used as a precedent for the movement of
potentially much larger volumes of water from the Missouri River to eastern
North Dakota.
Devils Lake Outlet
Devils Lake has no natural outlet. Thus, water levels rise and fall with
changes in precipitation and the rate of evaporation. Devils Lake, while
nominally in the Red River of the North basin, has not discharged water to the
Red for about 1,800 years. It is estimated from the archeological record that
Devils Lake may have overflowed to the Red River basin about four times in the
last 10,000 years or so and that it has been dry about four or five times. This
isolation may well have resulted in different biota in Devils Lake in comparison
with the Red River and Lake Winnipeg.
While Manitobans feel deep compassion and sympathy for the affected residents in
the Devils Lake basin - we know only too well the terrible impacts caused by
flooding - the proposed outlet will not relieve the flooding should the current
wet cycle persist.
Manitoba has several major concerns with a proposed emergency outlet. The first
is that water quality will deteriorate in the Red River due to the high level of
total dissolved solids, sulphates and the high salt content of Devils Lake
water. Recent water quality modelling done by the U.S. Army Corps of Engineers
indicates that operation of an outlet from the western region of Devils Lake
could cause the International Joint Commission objectives established for water
at the international border for total dissolved solids to be exceeded between 20
% to 33 % of the time. This represents a substantial degradation of present
water quality in the Manitoba portion of the Red River.
It is not always possible to identify or to predict the consequences of the
transfer of unknown biota from Devils Lake to the Red River. While much is known
of the large fish species, little is understood about microscopic organisms in
either system, such as fish pathogens, viruses, etc.
Of critical concern to Manitoba is the link between the Garrison diversion and
the stabilization of water levels in Devils Lake. It is well known that water
level stabilization in Devils Lake was one of the original goals of Garrison.
Recent public statements by local government officials in the Devils Lake basin,
state politicians and other government officials, as well as the North Dakota
Congressional Delegation clearly indicate that this remains the long-term goal.
While gaining an outlet to Devils Lake is the immediate goal, once water levels
recede naturally following the end of the present wet cycle -- as they have
historically -- the goal will then be to create an inlet to divert water from
the Missouri River. It is important to note that less than 10 years ago, North
Dakota was examining proposals to construct an inlet to Devils Lake from the
Missouri River because of concerns with low water levels.
There are other, internal solutions available to North Dakota. With or without
an outlet, additional flood protection works should be constructed and upper
basin storage needs to be pursued with much greater vigour.
The potential for imminent overflow of Devils Lake to the Red River basin is
minimal. Considerable time is available for serious and thoughtful examination
of all potential options and there is sufficient time to undertake a full and
complete environmental assessment of all options.
At the present time, the U.S. Army Corps of Engineers is undertaking an EIS
under NEPA for a federally-sponsored outlet project. It is expected that the EIS
will be completed by the fall of 2002 and will form a portion of a report
submitted to Congress. Because the EIS is being undertaken in accordance with
NEPA, some protection is provided to Manitoba and Canada.
However, North Dakota has indicated its intention to construct a temporary
outlet in a manner that would preclude the need for federal funds, federal
permits, or an EIS under NEPA. North Dakota has indicated that a temporary
outlet would be constructed should additional delays occur with the
federally-sponsored outlet project. This unilateral North Dakota outlet project
raises considerable concerns since it is being designed in such a way that an
EIS would be avoided.
Conclusions
As foreseen by the International Joint Commission in 1977, the invasion
of non-native species is having impacts of catastrophic proportions. The most
recent estimates of damage by the zebra mussel alone in the Great Lakes region
and adjoining waters in the northeast United States is $3 billion (US) each
year.
The permanent, large-scale diversion of waters between the Missouri River and
Hudson Bay basins represents an unacceptable risk of irreversibly damaging the
aquatic resources of Manitoba. It is a risk that can never be reduced to zero,
and a risk that has enormous consequences for Manitoba given the value of our
water resources, including those of Lake Winnipeg.
The construction of an outlet to Devils Lake, while providing little relief to
the present flooding situation, will not only pose similar, potential
catastrophic risks to the water resources of Manitoba, but also produce the
first link in North Dakota's long-term plan to stabilize water levels with both
an outlet and an inlet.
