Glen Canyon and in Grand Canyon represented an
increasingly vocal and significant economic force.
These river users heightened the National Park
Service's concerns about their missions in the face
of increasing use of the river. These issues were
creating a situation that could not be overlooked.
The board was interested in helping and appointed
a capable committee that eagerly undertook the
task. The members of the Committee to Review the
Glen Canyon Environmental Studies achieved solid
rapport with the GCES investigators and interaction
quickly became productive. The review presented in
this report was conducted with candor and received
in good spirit.
The committee was directed to (1) review and
advise on the Glen Canyon Environmental Studies in
progress, and give a general assessment of how well
these activities were achieving their intended
goals; (2) advise on interpretation of information
for impact analysis from the technical data
developed; (3) provide advice on the process of
identifying the environmental elements for ranking
operational alternatives for Glen Canyon Dam; and
(4) extrapolate from this case study
recommendations to others who may pursue similar
environmental studies at other sites in the future.
To fulfill its assigned tasks, the committee
provided general advice to the GOES research team
at three committee meetings, and the GCES project
manager was advised of the committee's progress
through quarterly summary reports. The assessment
of how well the GCES were achieving their intended
goals is given in detail in Chapter 4 of this
report. The assessment was difficult because the
GCES objectives were not clearly articulated at the
beginning, scientific objectives were confused with
management/policy objectives, and objectives
changed during the course of the study.
Members of the committee agree that changes in
the operation of Glen Canyon Dam were reflected in
measurable changes in the natural resources in the
