from those shown in the preferred alternative of the EIS. They were 11) increasing
the normal maximum flow from 20,000 cfs to 25,000 cfs and 12- increasing the
upramp rate from 2,500 cfs/hour to 4,000 cfs/hour. The ROD also changed the
triggering mechanisms for conducting beach/habitat-building flows. Instead of
conducting them in years when Lake Powell storage is low on January 1, they will
be conducted in years when Lake Powell storage is high and requires reservoir
releases in excess of powerplant capacity for dam safety purposes. Following the
signing of the ROD, the Secretary adopted a set of operating criteria and a 1997
plan of operation. This terminated the 1991 interim flow criteria.
The signing of the ROD began a new chapter in the history of Glen Canyon
Dam. In addition to meeting traditional water and power needs, the dam is now
being operated in a more environmentally sensitive manner. The EIS process
demonstrated the value of a cooperative, integrative approach to dealing with
complex environmental issues. The inclusion of all stakeholders resulted in a
process that will serve to guide future operations of Glen Canyon Dam, and become
a template for other river systems.
a. Adaptive Management
Section 1805 of the GCPA directs the Secretary to establish and implement
long-term monitoring programs on the natural, recreational, and cultural resources
of Grand Canyon National Park and Glen Canyon National Recreation Area. The
"Adaptive Management Program" (AMP) is a key element of the preferred
alternative outlined in the final EIS and implemented by the ROD. The program
provides for operation of Glen Canyon Dam for environmental purposes in Glen and
Grand Canyons in addition to traditional water and power generation.
The AMP provides a process for incorporating science and
recommendations from a diverse group of stakeholders in the evaluation and
management of future dam operations. The AMP calls for continued interaction of
managers and scientists to both monitor the effects of current dam operations on
the Colorado River ecosystem, and to conduct research on alternative dam operating
criteria that may be necessary to ensure protection of resources and improve natural
processes. The AMP identifies the following entities that contribute to the adaptive
management process: (1) Adaptive Management Work Group (AMWG), (2)
Technical Work Group (TWG-, (3) Grand Canyon Monitoring and Research Center
(GCMRCI, and (4) Science Advisory Board.
The AMWG is a Federal Advisory Committee chartered by the Secretary
consisting of a group of stakeholders-that are federal and state resource managers,
Native American tribes, power marketers, environmental groups, recreationists and
other interest groups. The AMWG was established to develop, evaluate, and
recommend alternative operations strategies for Glen Canyon Dam and make
recommendations to the Secretary. The AMWG does not displace federal agency
legal authority and responsibility to manage resources in the best interests of both
the environment and society.
In addition to creation of the AMWG, the TWG and GCMRC were created
to play vital roles as part of the adaptive management process. The TWG is
composed of technical representatives appointed by the AMWG. The TWG provides
the AMWG detailed guidance on issues and objectives, develops criteria and
standards for research and monitoring programs, provides information for annual
