emergency spillway. These decisions
were made under the assumption that
the risks of using either the service
or emergency spillways were equal,
against mounting evidence that this
was not the case. The risk trade-offs
were not fully informed, the relative
consequences were misunderstood
and the likelihoods of poor outcomes
were not being adjusted as new information became available. Acceptance
of the emergency spillway overflow
directly led to the necessity of the

massive downstream evacuation of
the public.
The IFT report laid out a number
of general lessons to be learned by
owners, regulators and consultants:
* Dam owners must develop and
maintain mature dam safety
management programs, which are
based on a strong top-down dam
safety culture. There should be
one executive specifically charged
with overall responsibility for
dam safety.

are not always sufficient to identify
risks and manage safety.
* Periodic comprehensive reviews of
original design and construction
and subsequent performance are
imperative.
* Appurtenant dam structures such as
spillways must not be overlooked.
* Compliance with regulatory requirements is not sufficient to manage
risk and meet dam owners' legal and
ethical responsibilities.
Many of these lessons are simple
and self-evident, invoking questions
as to why the dam safety industry has
not yet learned and applied them. The
IFT report argued that "...a critical
review of (dam safety) processes in
dam safety practice is warranted,
comparing their strengths and
