International Joint Commission Report Calls for
Regular Government Inspection of Dams
Without regular government inspection, the International Joint Commission (the Commission)
does not know if all dams along the U.S.-Canada border are safe.
The Commission has found that some dams and dykes along the border in Canada are not subject
to regular government inspections and that, although the situation is better in the United States,
there are also dams in the U.S. that are not inspected regularly. The Commission considers that
inspections arranged by the owners of these structures do not adequately protect the public
interest. Furthermore, the Commission is not satisfied that effective emergency action plans have
been put in place and tested for all structures.
The International Joint Commission has reported to the governments of the United States and
Canada on the arrangements that are in place to ensure the safe operation and maintenance of
dams and dykes subject to its jurisdiction in boundary areas. The Commission considers that
existing laws and practices in the United States and Canada are not sufficient to ensure that all
these structures are safe and has made recommendations for government action to protect people
and property in the two countries.
Failure of some of these dams and dykes could have catastrophic consequences for people and
property in the United States and Canada. The Commission has therefore recommended that
governments oversee the safety of these structures and require:
- Regular, periodic, complete and independent on-site inspections by qualified
- A reasonable timetable for implementation of all inspection report
- Establishment and regular testing of emergency action plans which take account
of possible eventualities and include detailed notification procedures,
identification of responsibilities, provision for transboundary coordination, and
inundation maps; and
- Public access to all reports and documentation relating to safety issues.
The Commission has also recommended that the United States and Canadian governments
arrange for joint oversight of structures that extend across the border.
If the Commission does not receive a substantive response to its report from the governments by
June 1, 1998, it may consider requiring owners to periodically provide the Commission with
copies of government safety inspection reports; confirm that all maintenance and repairs
recommended in those reports are being undertaken within a reasonable time; and to develop and
provide the Commission with copies of an emergency action plan.
In those cases where regular government safety inspection reports are still not available, the
Commission will consider possible means of addressing public safety in the interim.
The Commission is an international organization established by the 1909 Boundary Waters
Treaty between the United States and Canada to prevent boundary waters disputes and to settle
questions along the border. The Commission approves applications to construct and operate
certain projects in waters that flow along or across the boundary that affect levels or flows in the
other country. It also examines and reports on questions referred to it by both governments, and
alerts them to issues requiring their attention.
