protecting archaeological sites are showing only
temporary, modest improvement or even a decline.
Several new initiatives in the last two years
have started to address shortfalls in the Program
design. The most notable are: (i) Federal agencies
working with non-federal stakeholders to establish
specific, measurable, and realistic future conditions
and outcomes in the Program; (ii) the Working
Group has established an
ad hoc
group to evaluate
its charter and provide recommendations to
improve the Program's governance structure and
operating procedures; and (iii) the Department
is now engaged in meaningful consultation with
Native American tribes to recognize their values,
knowledge, and priorities for the Program. In
addition, an experimental protocol that would
allow repeated HFEs during appropriate sand-
supply conditions below the dam is expected in
early 2011. The Department has also announced
that it intends to develop an Environmental
Impact Statement in 2011 to support a long-term
experimental and management plan related to dam
operation. Addressing fundamental value conflicts
by the use of collaborative management processes
and decision-support tools will be crucial to the
success of these efforts.
If implemented successfully, these new initiatives
offer great potential for improving the effectiveness
of the Program. This could result in an operational
protocol for the dam that improves downstream
resources, features and uses in the Glen Canyon
National Recreation Area and the Grand Canyon
National Park while meeting the energy needs and
water supply obligations of the western United
States. Maintaining credible and effective research
and monitoring effort to evaluate the effects of
experimental and management actions will be a
major component in achieving these objectives.
assistance. The scientific findings discussed in this
chapter are largely the result of many years of
excellent research conducted by USGS scientists
and its cooperators. Most of the scientific studies
were funded by hydropower revenues provided
by the U.S. Bureau of Reclamation through the
Glen Canyon Dam Adaptive Management Program
(GCDAMP). The GCDAMP was established in 1997
to provide long-term research and monitoring of
the Colorado River below Glen Canyon Dam.
