| + | |
| + | It is quite clear that when Congress enacted the Grand Canyon Protection Act of 1992, 106 |
| + | Stat. 4669 (GCPA), it intended to maintain all that had gone before the Compacts, the Park units, |
| + | and Glen Canyon Dam downstream NPS resources without interfering with the "Law of the |
| + | River," including compact and treaty obligations for water delivery (GCPA, section 1802(a) and (b)). |
| + | |
| + | The Senate Report on the bill puts it quite simply: The primary purpose of this title is to authorize |
| + | changes in the operation of Glen Canyon Dam to prevent damage to downstream resources, |
| + | principally the dam's power operations. The Secretary's responsibilities for water storage, allocation |
| + | and delivery act as limits on the Secretary's discretion in implementing the GCPA. It is also clear |
| + | that Congress understood that these objectives would have certain costs in the form of lost |
| + | incremental hydropower generating opportunity (GCPA, section 1809) and that the existence of the |
| + | dam was to be taken as a given. |
| + | |
| + | The basic question Congress was addressing was how Glen Canyon Dam operations might be |
| + | modified within the provisions of existing law so as to improve conditions for downstream NPS |
| + | resources (with similar benefits certainly occurring on other similarly situated lands). The GCPA |
| + | itself does not direct consideration of cultural resources within the boundaries of Native American |
| + | reservations, only "the values for which Grand Canyon National Park and Glen Canyon National |
| + | Recreation Area were established," although all federal agencies have similar obligations under other |
| + | law. The entire adaptive management program (AMP), including the Grand Canyon Monitoring and |
| + | Research Center and the Adaptive Management Work Group, must be understood within this |
| + | context. In accordance with section 1804 of the GCPA, the EIS was conducted to attempt to find an |
| + | answer to that question, and the 1996 ROD was the Department's best first answer. Recognizing |
| + | that more experience and knowledge with operations might enable further refinements in operations |
| + | and might further improve downstream resource conditions, however, Congress added section 1805 |
| + | to the GCPA. This section required the Secretary to "establish and implement long-term monitoring |
| + | programs and activities that will ensure that Glen Canyon Dam is operated in a manner consistent |
| + | with section 1802," namely, "to protect, mitigate adverse impacts to, and improve the values for |
| + | which Grand Canyon National Park and Glen Canyon National Recreation Area were established," |
| + | within the parameters of other applicable law and the physical constraints of the dam. Accordingly, |
| + | the Department included in the EIS and in the ROD the provisions setting up the AMP, thereby |
| + | allowing for further refinement of and changes to dam operations to better meet the GCPA |
| + | objectives. |
| + | |
| + | The charge given to the AMWG in its Charter is to "facilitate the AMP, recommend suitable |
| + | monitoring and research programs, and make recommendations to the Secretary as required to meet |
| + | the requirements of the Act. The scope of the AMWG responsibility, therefore, is to identify |
| + | aspects of dam operations that can be modified to beneficially affect the downstream resources |
| + | identified as the focus of study (i.e. "the target") in the EIS. This covers flow rates, ramping rates, |
| + | periodicity of peak flows, monitoring sediment input rates and the relation of sediment movement to |
| + | water release and ramping rates, chemical content and temperature of releases, among possible others |
| + | --any aspect of dam operations, in other words, which has a reasonably demonstrable effect on the |
| + | downstream resources sought to be improved by the GCPA. The key to the scope of AMWG's |
| + | responsibilities is whether a specific desired resource effect downstream of the dam can be achieved |
| + | through some manipulation of dam operations. Under the ROD, the upper limit of planned release |
| + | level is 45,000 cfs. Long-term monitoring and research, including test flows within the current |
| + | range of authorized operations, are intended to enable finer and finer tuning of operations over time, |
| + | as additional knowledge and experience are gained, to better achieve the target mix of resource |
| + | benefits, as outlined in the EIS, pages 54-65. [https://www.usbr.gov/uc/progact/amp/amwg/2002-07-17-amwg-meeting/Attach_10b.pdf] |

AMWG FACA Committee Guidance

It is quite clear that when Congress enacted the Grand Canyon Protection Act of 1992, 106
Stat. 4669 (GCPA), it intended to maintain all that had gone before the Compacts, the Park units,
and Glen Canyon Dam downstream NPS resources without interfering with the "Law of the
River," including compact and treaty obligations for water delivery (GCPA, section 1802(a) and (b)).
The Senate Report on the bill puts it quite simply: The primary purpose of this title is to authorize
changes in the operation of Glen Canyon Dam to prevent damage to downstream resources,
principally the dam's power operations. The Secretary's responsibilities for water storage, allocation
and delivery act as limits on the Secretary's discretion in implementing the GCPA. It is also clear
that Congress understood that these objectives would have certain costs in the form of lost
incremental hydropower generating opportunity (GCPA, section 1809) and that the existence of the
dam was to be taken as a given.
The basic question Congress was addressing was how Glen Canyon Dam operations might be
modified within the provisions of existing law so as to improve conditions for downstream NPS
resources (with similar benefits certainly occurring on other similarly situated lands). The GCPA
itself does not direct consideration of cultural resources within the boundaries of Native American
reservations, only "the values for which Grand Canyon National Park and Glen Canyon National
Recreation Area were established," although all federal agencies have similar obligations under other
law. The entire adaptive management program (AMP), including the Grand Canyon Monitoring and
Research Center and the Adaptive Management Work Group, must be understood within this
context. In accordance with section 1804 of the GCPA, the EIS was conducted to attempt to find an
answer to that question, and the 1996 ROD was the Department's best first answer. Recognizing
that more experience and knowledge with operations might enable further refinements in operations
and might further improve downstream resource conditions, however, Congress added section 1805
to the GCPA. This section required the Secretary to "establish and implement long-term monitoring
programs and activities that will ensure that Glen Canyon Dam is operated in a manner consistent
with section 1802," namely, "to protect, mitigate adverse impacts to, and improve the values for
which Grand Canyon National Park and Glen Canyon National Recreation Area were established,"
within the parameters of other applicable law and the physical constraints of the dam. Accordingly,
the Department included in the EIS and in the ROD the provisions setting up the AMP, thereby
allowing for further refinement of and changes to dam operations to better meet the GCPA
objectives.
The charge given to the AMWG in its Charter is to "facilitate the AMP, recommend suitable
monitoring and research programs, and make recommendations to the Secretary as required to meet
the requirements of the Act. The scope of the AMWG responsibility, therefore, is to identify
aspects of dam operations that can be modified to beneficially affect the downstream resources
identified as the focus of study (i.e. "the target") in the EIS. This covers flow rates, ramping rates,

--any aspect of dam operations, in other words, which has a reasonably demonstrable effect on the
downstream resources sought to be improved by the GCPA. The key to the scope of AMWG's
responsibilities is whether a specific desired resource effect downstream of the dam can be achieved
through some manipulation of dam operations. Under the ROD, the upper limit of planned release
level is 45,000 cfs. Long-term monitoring and research, including test flows within the current
range of authorized operations, are intended to enable finer and finer tuning of operations over time,
as additional knowledge and experience are gained, to better achieve the target mix of resource
benefits, as outlined in the EIS, pages 54-65. [1]
