Agenda Item

Ad Hoc Group Review/Dissolution of Groups 

Action Requested

 The TWG Chair proposes the following changes to the current status of ad hoc groups and 

seeks TWG agreement. We should update the member lists and current charges for these 

groups. 

Ad hocs that should be retained: 

Budget: Standing. Chair Dennis Kubly. Established June 22, 2009. 

Charge: The Budget Ad Hoc (BAHG) will develop an annual budget recommendation 

(biennial) for TWG utilizing input from the CRAHG, GCMRC, and BOR. This is to include 

an initial budget recommendation during the spring TWG meeting and a final 

recommendation during the summer TWG meeting. The BAHG should also draft an update 

to Appendix H in the Strategic Plan which describes the current budget process. Originally 

established November 12, 2003. 

Members: Mary Barger, Norm Henderson, Mike Yeatts, Kerry Christensen, Rick Johnson, 

Glen Knowles, Don Ostler, Larry Stevens, Bill Persons, Steven Mietz, Bill Werner 

Cultural Resources: Standing. Chair Kurt Dongoske. Established June 22, 2009. 

Charge: The Cultural Resources Ad Hoc (CRAHG) will review the annual budget 

recommendation on cultural program issues and make recommendations to the BAHG. 

Additionally, the CRAHG will review the treatment plan, the cultural properties monitoring 

program, and make recommendations to TWG. Originally established September 6, 2001. 

Members: Jan Balsam, Charley Bullets, Kerry Christensen, Kurt Dongoske, Mike Yeatts 

Humpback Chub: Chair needs to be determined. Established June 22, 2009. 

Charge: Develop a comprehensive research and management plan for humpback chub for 

TWG and AMWG review. Originally established January 28, 2003. 

Members: Bill Davis, Norm Henderson, Mark Steffen, Larry Stevens, Dennis Kubly, Bill 

Persons, Rick Johnson, Steve Mietz 

Species of Concern: Chair Larry Stevens. Established June 22, 2009. 

Charge: Provide a draft report to be presented to AMWG on or before May 1, 2011, that 

contains the following with regard to species of management concern in the CRE: a review 

of information about and assessment of the status of habitat needs and availability, and 

ecosystem roles of the species. The ad hoc should utilize the expertise of GCMRC in the 

development of the report. 

Members: 

Geomorphological Model: Chair needs to be determined. Established June 22, 2009. 
Ad Hoc Group Review/Dissolution of Groups, continued 

 Page 2 

Charge: Develop a scope and objectives for a geomorphological model that would evaluate 

dam effects on cultural sites, with no budgetary implications for FY10-11, to be provided to 

TWG as soon as practicable. 

Members: 

Ad hocs that should be disbanded: 

1. Experimental flows: no longer necessary. 

2. Sediment: this group has completed all of their tasks and has had difficulty completed 

tasks within expected timeframes. If a sediment ad hoc is necessary in the future, the 

group could be reconstituted for that particular activity. 

3. Kanab ambersnail: no longer necessary. 

4. Aquatic PEP: no longer necessary. 

5. Native fish: no longer necessary, the humpback chub ad hoc is currently reviewing issues 

related to native fish. 

6. Non-native fish control: no longer necessary. 

7. Core monitoring: not currently necessary. There may be more work needed to evaluate 

the General Core Monitoring Plan to be released this spring. I propose we disband this 

group and reconstitute a similar group if necessary. 

8. Long-term experimental plan: no longer necessary. 

9. Cultural resources design: no longer necessary, however, the tasks should be moved to 

the CRAHG. 

10. TWG small group: no longer necessary. 

11. Science planning group: no longer necessary. 

12. Facilitation: This group provided a report at the October 2008 TWG meeting and again 

at this meeting.

Shane Capron, Chair, Technical Work Group 

Previous Action Taken

See attached list of ad hoc groups. 

See attached report from April 09, 2008 by Kurt Dongoske. 

Background Information

In general, I propose that if an ad hoc does not have a current need then we should disband it unless 

we agree that it should be a standing committee. The TWG operating procedures list one of the 

Chair responsibilities as: “Organize or disband Ad Hoc task groups per TWG direction.” Therefore, 

I am proposing this approach and looking to TWG for review and agreement. 

Walking through ad hoc table, we should ask the following questions: 

x Does the TWG want to maintain this ad-hoc? 

x If the ad hoc is maintained, who is the chair 
Ad Hoc Group Review/Dissolution of Groups, continued 

 Page 3 

x What is the near-term schedule for this ad hoc? When and where will they next meet? What 

products are due and when? When can TWG expect to receive one or more reports from 

this group?

Questions to Consider

 Are these the appropriate set of standing ad hoc 

groups?

 Do these standing ad hoc groups have a clear 

charge?

 Are their charges appropriate or should they be 

revised?

 What should be the duration of TWG ad hocs?

 Is there a need to develop standard TWG ad 

hoc operating procedures?

Benefits of Operating Procedures

for TWG Ad Hocs

 Develop consistent procedures for reaching 

recommendations

 Consistent reporting requirements to the TWG

 Establish membership criteria for ad hocs

TWG members vs technical representatives

 Define role of GCMRC (and other agency 

technical representatives) in TWG ad hocs

 Establish consistency among TWG ad hocs

Experimental 

Flows 

Date Established: November 8, 2000 Chair: Randy Peterson 

Charge: (1) Develop a program of experimental flows to comply with the RPA in the

Date AHG Disbanded: 

Experimental 

Flows 

Date Re-established: Feb. 2, 2004 Chair: Dennis Kubly 

Charge: (paraphrased from the TWG 2/4/04 minutes: The TWG would recommend to the 

AMWG that we pursue an experimental action plan with GCMRC for 06 and beyond utilizing 

the MATA process. Dennis said the group will have to look at the fall steady flows and ask 

whether there is money to measure them. The dam operations experiment is one of the 

projects that was funded and its intent was not originally to fund MATA; they did that because 

they didn’t have fall steady flows. There’s enough money to cover that from somewhere else 

but Dennis doesn’t feel comfortable agreeing upfront that MATA is used to replace that 

experiment.”
