While many organizations have interests in the Grand Canyon river corridor and the impacts of Glen Canyon Dam on downstream resources, there is a limited set of official “member” organizations and agencies in the adaptive management program. Pages 3-4 of the original GCDAMP Charter of 1997 specified the interest groups that would make up the membership of GCDAMP. They included five federal agencies, six tribes, the AZ Game and Fish Dept, one representative from each of the seven Colorado River Basin states, and two representatives each from environmental groups, recreation interests, and purchasers of federal hydropower from Glen Canyon Dam.
The term “stakeholders” is sometimes used to refer to these member groups, but it is an inexact term that can include interest groups that are not formal members of the GCDAMP.
The original membership list has changed very little since 1997, although the specific organizations and individuals representing those interest groups has changed over time. Here is the membership list specified in the 2019 GCDAMP charter re-authorization:
- Secretary’s Designee, who will serve as Chairperson for the AMWG.
- One representative each from the following entities:
- The Secretary of Energy (Western Area Power Administration)
- Arizona Game and Fish Department
- Hopi Tribe
- Navajo Nation
- San Juan Southern Paiute Tribe
- Southern Paiute Consonium
- Pueblo of Zuni
- One representative each from the seven basin states:
- New Mexico
- Representatives each from the general public as follows:
- Two from environmental organizations
- Two from the recreation industry
- Two from contractors who purchase Federal power from Glen Canyon Powerplant
- One representative from each of the following DOI agencies as ex-officio non-voting members:
- Bureau of Reclamation
- Bureau of Indian Affairs
- U.S. Fish and Wildlife Service
- National Park Service
While other tribes have a declared interest in the Grand Canyon, not all have a representative on the GCDAMP. The Havasupai Tribe in particular, whose reservation is contained within the Grand Canyon and extends to the river corridor, has not participated in the adaptive management program and is not specified as a GCDAMP member.
The representatives of the basin states are nominated by each states’ governor and they normally represent the state’s water interests.
The “environmental organizations” category has seen the most variation in representation. In the early years, the two environmental representatives came from the Grand Canyon Trust and American Rivers. Other environmental groups lobbied for representation but those were the two groups chosen by the Secretary of Interior to send a representative. Around 2004, American Rivers dropped out and was replaced by the Grand Canyon Wildlands Council. Around 2011 the Grand Canyon Trust dropped out and was replaced by the National Parks Conservation Association.
The groups representing recreational interests and hydropower interests have been stable. Grand Canyon River Guides and Trout Unlimited have represented recreation interests since the beginning, while the Colorado River Energy Distributors Association (CREDA) and the Utah Associated Municipal Power Systems (UAMPS) have represented federal hydropower purchaser interests since the beginning.
The individuals who represent the member organizations serve renewable three year terms. Normally the interest groups or agencies will designate a representative, who is vetted and forwarded by AMWG to the Secretary of Interior for appointment. Occasionally an interest group will nominate a representative that the Secretary will reject. To avoid this, nominations tend to be vetted internally before they are formally recommended to the Secretary. Members of both AMWG and TWG are appointed in this manner.
