Glen Canyon Dam Technical Work Group Meeting 

August 30-31, 2017 

Summary of Actions Taken 

 Draft Minutes for April 20-21, 2017, meeting were approved by consensus. 

 Budget Motion: The TWG recommends that the AMWG recommend for approval the Glen Canyon 

Adaptive Management Program Triennial Budget and Work Plan – Fiscal Years 2018-2020 (Draft August 

17, 2017) to the Secretary of Interior with the following changes: 

1. Approving GCMRC’s Project C as written contingent upon adding language to Reclamation’s 

Project C.7., Experimental Vegetation Treatment, for funding tribal engagement as partners in 

planning and executing the experiment. 

2. Approving GCMRC Project D with no funding for D.1, D.2 or D.3, but with funding for D.4. 

3. GCMRC Project G.5 – Add one annual seining trip funded by the Native Fish Conservation 

Contingency Fund. 

4. Approve GCMRC Project I with an additional Spring system-wide monitoring trip to I.1 and a Fall 

Diamond Down trip 

5. GCMRC Project E. with reinsertion of Project E.7.1, Aquatic Vegetation Surveys, and Project 

E.7.2, Artificial Streams. 

6. Without a net increase to the budget, add a new Project N, Hydropower, to the GCMRC work plan 

with work efforts that include (also add to Reclamation Project C with complementary language): 

a. Develop Glen Canyon Dam operational experiments to meet the hydropower objective. 

b. Consider and estimate impacts of experiments on hydropower as part of experimental 

design. 

c. Incorporate total hydropower value into Decision Support Systems being developed in 

GCMRC Project J.2 

d. Utilize WAPA and Reclamation hydropower data, as available, and include WAPA 

technical staff in the development of models, design of experiments, and monitoring 

metrics. 

7. GCMRC Project J. Socioeconomics as written with additional language: 

a. Clarifying language will be added to Project J.2 that indicates integrating hydropower 

analysis into the modeling of trout management flows will be a primary focus. Incorporating 

hydropower analysis follows the development and integration of rainbow trout and 

humpback chub population models and cost-effectiveness analysis, used to identify 

efficient management actions to meet adult humpback chub abundance goals. 

Hydropower analysis in J.2 is an incremental step in the development of applied decision 

and scenario analysis research at GCMRC. Adding hydropower analysis into the applied 

decision and scenario analysis research is timely provided the proposed LTEMP EIS 

experiments, including trout management flows. 

b. A workshop will occur with GCMRC staff and GCDAMP stakeholders in fiscal year 2018 to 

review and discusses the trade-offs between trout management flows, expected 

downstream rainbow trout and humpback chub outcomes and associated costs of 

management actions, including hydropower. This workshop will provide an opportunity to 

explore opportunities to improve hydropower resources while meeting downstream 

rainbow trout and humpback chub resources goals as defined in the LTEMP EIS. 

8. Approve Reclamation Project D. with addition of identifying how Reclamation Project D elements 

and GCMRC project elements address stipulations in the PA and track their progress. 

9. Increase funding for Reclamation Project D.10 to a target balance of about $200,000 by the end of 

FY 2018. 

10. Approve Reclamation Project C. with changes to allow allocation of some funds from Reclamation 

Project C.5 into Reclamation Project D.10.

Meeting Recorder: Linda Whetton 

Welcome and Administrative: Mr. Shanahan welcomed the members and the public. Introductions 

were made and a quorum determined. 

 Approval of April 20-21, 2017, Meeting Minutes. Pending one edit, the minutes were approved by consensus. 

 Review of Action Items. No action required. 

 Next Meeting Date: A “doodle” poll will be sent requesting availability for a conference call during October 9-13. 

 Update on monitoring and research trips (Attachment 1). Mr. VanderKooi distributed a table listing field trips that will 

be launching mid-October. This will be a recurring agenda item. Reclamation and NPS will provide input as well. 

 Ad Hoc Group Updates – Mr. Shanahan. Ad hoc groups have been coordinating with their members in support of 

budget and work plan development activities. 

 Cultural Resources Activities Update – Dr. Rinkevich. Kurt Dongoske stepped down as the CRAHG chair. The tribes 
Glen Canyon Dam Technical  Work Group

Final Minutes of August 30‐31, 2017, Meeting Page 3

will talk among themselves regarding who will be the new chair. Dr. Grantz said the PA was signed by all parties to 

the agreement, and it is currently being reviewed by the Historic Preservation Advisory Council. 

 Green Sunfish Update – Mr. Hyde. The exclusionary barriers didn’t get installed until April. Within a month NPS 

verified that the GSF had moved back into the upper slough even though there was a successful ammonia treatment 

last year. Approximately 15-20 GSF were found in the Nov-April period. Most of the bigger fish had been removed by 

electrofishing but at least two were able to spawn. About three weeks ago black plastic across the entire upper slough 

(1/3 acre) was installed to see if this would disrupt the oxygen cycle and heat the pond. As of last Thursday, there 

were still several GSF visible, even though the oxygen levels had dropped from 10.5 down to 1.5. The black plastic 

will be left in place for two more weeks. If there are still GS, one more ammonia treatment will be performed in late 

September in anticipation of a possible HFE. Should an HFE occur, the exclusionary barriers will be put back into 

place the week following the HFE. 

 Update on Plan for Controlling High Risk Aquatic Invasive Fish Species – Mr. Billerbeck. Given all the complications 

with recent increases in BT and feedback received, the NPS is developing a more comprehensive plan. They are 

moving forward with cooperating agency agreements and consulting with the tribes. NPS hopes to get meetings 

scheduled soon and start public scoping in November-December. Reclamation is assisting with some of the analysisReclamation’s Provo construction office and Denver Technical Services Center will evaluate potential engineering 

issues related to the sloughs. 

TWG Chairperson and Vice Chairperson Election – Dr. Grantz. The TWG Chair position is a oneyear term, Mr. Shanahan’s term ends Sept. 30, 2017. Consequently it’s time to re-elect the TWG Chair 

and Vice-Chair. Nominations were requested. Ms. Roefer nominated Mr. Shanahan as the TWG Chair, 

which was seconded by Mr. Yeatts. With a verbal vote, Mr. Shanahan was approved as the TWG Chair 

for FY18. Mr. Capron nominated Ms. Kartha as the TWG Vice-Chair which was seconded by Ms. Brown. 

By verbal vote, Ms. Kartha was approved as the TWG Vice-Chair for FY18. 

DOI FACA Review Update – Dr. Grantz. In May, Reclamation received notification that all DOI FACA 

committees were undergoing a review; all committee and subcommittee activities were suspended. 

Reclamation applied for and received a waiver in June to resume subcommittee activities in order to 

prepare the FY18-20 budget and work plan, and to prepare for a potential BT Workshop, a possible fall 

HFE, and a tentative AMWG meeting September. The waiver was put in place and Reclamation is 

planning for an AMWG meeting on September 20, 2017 in Phoenix. The Federal Register Notice for that 

meeting was published on Aug. 29, 2017. Even though the FACA review is ongoing, DOI committees 

and subcommittees can resume their work beginning in September. 

Update on Hydrology and GCD Operations (Attachment 2) – Mr. Davidson. The April through July 

unregulated inflow to Lake Powell was 8.17 maf, or 114 percent of average. Snowpack peaked in early 

March at 126 percent of average. Lake Powell inflows peaked at 60,600 cfs on June 13th, and the 

reservoir elevation peaked at 3,635.8 feet, with a content of 15.5 maf, or 64% full. Lake Powell current 

operations are in the Upper Elevation Balancing Tier (UEBT). Water year 2017 unregulated inflow is 

currently forecasted to be 12.1 maf, or 111% of average and 9.0 maf will be released from Glen Canyon 

Dam. Lake Powell is currently 61% full with 14.9 maf in storage. The current pool elevation is 3,630 feet; 

70 feet below full pool (3,700 feet) and 140 feet above minimum power pool (3,490 feet). The minimum 

probable, most probable and maximum probable release volumes from Glen Canyon Dam for water year 

2018 are projected to be 9.0, 9.0, and 13.8 maf, respectively. 

Dam Maintenance Schedule. Mr. Davidson. Glen Canyon Dam power plant maintenance is a continual 

process and management keeps the maximum number of power units online in November for a 

potential HFE. However, this November only six of the eight units will be available because of ongoing 

maintenance activities. Assuming current unit efficiencies given the reservoir elevation, these six units 

could release approximately 20,700 cfs. Combined with the river bypass tubes of 15,000 cfs, the total 

release from Glen Canyon Dam could produce a peak release of 35,700 cfs for an HFE. As of Sept. 6, 

2017 there isn’t enough sediment input to trigger a fall 2017 HFE.

Glen Canyon Reach Rainbow Trout Experimental Stocking (Attachment 3) – Mr. Cantrell. 

Reclamation, Park Service and Arizona Game and Fish did monitoring on July 4, 2017. AGFD proposed 

stocking in May but postponed in order to discuss shared goals. The goal is to maintain a fully 

recreational RBT fishery in Lees Ferry, while maintaining healthy populations of all native fish including 

HBC and RBS populations. Lees Ferry has been stocked since 1964, the last stocking was in 1998. Due 

to declines in early 2000 and 2005, or AGFD proposed stocking again. At that time AGFD and others 

received a Notice of Intent to sue from the Center for Biological Diversity and Upper Colorado Living 

Waters based on jeopardy for HBC and RBS. At the time there was little information about movement 

within Lees Ferry and affects to HBC and RBS in the lower Colorado River. Today there is low trout 

abundance, angler days are down, businesses are closing, and the river guides are suffering. The HBC 

population is exceeding 11,000. After working with the anglers, AGFD developed some objectives and 

goals for the fishery. AGFD plans to stock 13,000 triploid RBT annually between April 1, 2017 and 

October 15, 2021. Mr. Cantrell said he would send out information to people on proposed work to be 

done. 

 Concern was expressed that planning has taken place with very little stakeholder involvement. 

 The foodbase is limiting the fishery and will effect native fish in the system. The RBT will be the least of issues to be 

concerned about. 

 The Pueblo of Zuni is very concerned about stocking trout in Lees ferry, mechanical removal and the taking of life. 

 FWS isn’t comfortable using the calculations provided by AGFD. Your website states you don’t expect any take. 

 The Hualapai Tribe wants consultation on this action. 

 Strongly support the request for collaboration and request for working with federal agencies on environmental 

compliance. 

Brown Trout Workshop Update – Dr. Grantz. A Brown Trout Workshop will be held at the DoubleTree 

Hotel in Tempe, Arizona, on September 21-22 (1.5 days), directly following the AMWG meeting. A white 

paper will be distributed before the workshop and updated after the workshop. Dr. Mike Runge will 

facilitate the workshop. 

Status of Developing Triennial Budget and Work Plan (Attachment 4) ̶ Mr. Shanahan. The BAHG 

has been working with the Interior agencies to provide input on the budget and work plan. In order to get 

to a budget recommendation, the TWG will use the “red, green and yellow” cards indicating their 

acceptance level for the various budget components. The group will go through all of the projects very 

quickly, each member will display a green, yellow or red card and then have discussion on the most 

difficult (red) projects/elements first. A reminder on the card usage: 

Green = no concerns, support 

Yellow = need more information or minor concerns, but would not block consensus 

Red = major concerns, and will block consensus (members need to very specific) 

Budget Ad Hoc Group (BAHG) Input to the Triennial Budget and Work Plan (Attachment 5) – Mr. 

Capron. The BAHG prepared a consensus document from meetings held and comments offered. He 

thanked Seth for chairing some of the meetings and assisting with that document. A meeting was held on 

August 4 to coordinate the final comments and get consensus on what they could accomplish given the 

shorter timeline. There were a lot of things they didn’t get consensus on and in the past there was a 

process whereby they could elevate issues to the DOI level; those issues will be addressed in today’s 

meeting. That document went to Reclamation and GCMRC for their consideration and is available for 

TWG review. 

GCMRC Response to Input on TWP – Mr. VanderKooi. Scott summarized the process used and past 

guidance documents that are still relevant to bringing continuity to the program. 

 There were questions about research characteristics and methods. Rather than pull them out, they were left in the 

chapter narratives. 
Glen Canyon Dam Technical  Work Group

Final Minutes of August 30‐31, 2017, Meeting Page 5

 A question about the Science Advisor role was deferred to either the GCDAMP as a whole or to Reclamation. 

 There was a suggestion that projects should be considered in a 20-year context. 

 The Fish PEP conducted last summer recommended looking at a theoretical approach with multiple hypotheses, 

collecting data, comparing against those hypotheses and taking that information forward. 

 There was a request to identify research activities or new experiments that might occur as conditions warrant. There 

are at least three projects that have separate sections that are condition dependent (e.g., an extended duration HFE). 

 GCMRC will continue to look for opportunities for tribal participation and possibly identify additional funding sources. 

 Power analysis has been done for some projects and will be conducted with going forward. 

Reclamation Responses on TWP – Dr. Grantz. The Native Fish Conservation Contingency Fund for 

emergency conservation needs generated the most interest. She purposely didn’t include an amount 

because analysis hasn’t been done to determine what that number should be. In talking with other 

stakeholders, she’s comfortable including past targeted information and information on how excess funds 

would be used. 

Resolution of Triennial Budget and Work Plan Items that Lack Consensus and Development of 

Budget Recommendation to the Adaptive Management Work Group (AMWG) – Mr. Shanahan 

advised the members that if there is something missing, they need to be prepared to offer a change. 

 Hydropower is a resource and needs to be included in the work plan. Need experiments associated with fluctuating 

flow factors, ramp rates, and the 8K cap. Need analysis that was undertaken as part of the alternatives that were 

proposed within LTEMP. 

 Need to capture results of implementing the LTEMP. 

The group reviewed the projects and identified which ones were supported and those with concerns by 

raising red, yellow and green cards.

Welcome and Administrative: Mr. Shanahan welcomed the members and the public. Introductions 

were made and a quorum determined. Unresolved issues from yesterday will be dealt with later. 

Resolution of Triennial Budget and Work Plan Items that Lack Consensus and Development of 

Budget Recommendation to the AMWG – Mr. Shanahan. It was decided to review all the projects in 

preparation for a final vote. Mr. Capron suggested that after reviewing all the projects and possibly 

missing something, he wanted to reserve the right to hold up a red card. The TWG was agreeable to 

that. 
Glen Canyon Dam Technical  Work Group

Final Minutes of August 30‐31, 2017, Meeting Page 7

Project D. Effects of Dam Operations and Vegetation Management for Archaeological Sites 

 Comments on Project D: 

 D1. The effect of aeolian sand maybe a preservation component, but it’s not the responsibility of the AMP. No funds 

should be spent to document windblown sand.

 D2. NPS has responsibility for GCD terraces. If they want expertise, they should pay for it.

 D3. Is integrated into D.1 and we don’t need to know where available sand deposits are. 

D4. Putting the cart before the horse. We haven’t discussed what the HPP looks like. Have concerns with GCMRC 

putting information together.

 A portion of funding should go into a contingency fund for arch sites. The BOR has a project with $25K for mitigation 

of sites and that won’t pay for anything. Let’s take money and fund real mitigation for arch sites that are at risk.

 Suggest reworking D2 to have the experimental component that is more similar to when the actual activity is 

occurring.

 Make sure to use basin funds appropriately.

Result: D.1, D.2, and D.3 changed to eliminate funding, but fund D.4 

Project G. Humpback Chub Population Dynamics throughout the Colorado River Ecosystem 

Comments on Project G: 

 Not sure there is enough money to do experimentation and follow-up on these experiments. 

 Concerned about the loss of backwater seining that’s been dropped from the work plan. 

 Add aggregation monitoring trip for HBC. 

Result: Add one annual seining trip funded by the native fish conservation contingency fund. 

Project I. Warm Water Native and Non-Native Fish Research and Monitoring 

Comments on Project I: 

 Have serious problems based on management decisions. 

 The measures to correct will include substantial taking of life in other areas. 

 Don’t see cross-integration or synthesis on this or other projects. 

Result: Approve with one additional Spring system-wide monitoring to 1.1 and a Fall Diamond Down trip. 

Project E. Nutrients and Temperature as Ecosystem Drivers: Understanding Patterns, 

Establishing Links and Developing Predictive Tools for an Uncertain Time. 

Result: Reinsertion of Project E7.1 Aquatic vegetation surveys and Project E7.2 Artificial Streams 

Project F. Aquatic Invertebrate Ecology 

Comments on Project F: 

 Not sure there is enough experimentation in this project. Research related to substrate got dropped. 

 This is doing research just for research sake. 

Project J. Socioeconomic Research in the Colorado River Ecosystem 

Comments on Project J: 

 Need to add another GCMRC project for work associated with hydropower monitoring and other investigations. 

Result: “Project N” will be a new project under GCMRC integrating hydropower analysis into the 

modeling of trout management flows as a primary focus. 

Project L. Remote Sensing Overflight in Support of Long-term Monitoring and LTEMP 

Comments on Project L: 

 This has been a condensed process. 

 When first presented, the cost was divided – don’t understand statement of setting aside $75K. 

 Work is necessary and provides information about large scale changes in the river corridor. 

Project H. Salmonid Research and Monitoring 

Comments on Project H: 
Glen Canyon Dam Technical  Work Group

Final Minutes of August 30‐31, 2017, Meeting Page 8

 Can’t support if there is killing of trout via Trout Management Flows. 

 Propose to reduce a number of surveys from 3 to 2 and add in the additional monitoring for the fall trip. 

The votes on each project were captured in a final document (Attachment 6). 

 

The group developed a final budget motion. All changes will be included in the next version of the 

Triennial Budget and Work Plan for the AMWG to review at their next meeting. The budget motion can 

be found on page 1. There was an objection to moving the motion by consensus. The following vote was 

recorded: Red – 1 (Kevin Dahl), Green – 10, and Yellow – 2 (Carlee Brown, Mike Yeatts). 

The motion passed by majority with NPCA voting in the minority. The NPCA will write a minority report 

and provide to the AMWG before its next meeting. Dr. Grantz advised that the report needs to be 

submitted to Reclamation within the next three days in order to be included in the AMWG pre-meeting 

materials. 

Potential Fall Flow Experiment (HFE) ≤ 192 Hours; status of resources – Dr. Grantz. Due to time 

constraints, this item will be discussed at the next AMWG meeting. 

Request for Agenda Items for Next Meeting – Mr. Shanahan. It was decided to hold a half-day 

webinar on October 10, 2017 to discuss the potential for a Fall HFE and other TWG issues. Members 

should submit proposed agenda items to Mr. Shanahan by September 8, 2017.
