in year 2, and $54,000 in year 3) and GCMRC D.3 (approximately $28,000 in 

year 1, $29,000 in year 2, and $0 in year 3). 

3. Include Havasu Creek and LCR-mouth gage in GCMRC A.1 at 17,000/year. 

4. Please change GCMRC Project N verbiage (Pg 294) from “For example, 

modeling a change in ramp rates to maintain or improve the hydropower and 

recreational resource objectives is a possible application of GCMRC Project N.” 

to: “For example, modeling a change in ramp rates to improve the 

hydropower resource objective is a possible application of Project N.”

ACTION ITEMS

1. Members are asked to support the family of Charley Bulletts with cards and 

letters. Please contact Theresa Pasqual for correspondence instructions. In 

addition, AMWG and TWG members are asked to share photos and memories of

Charley with Reclamation to support a remembrance to be held during the 

August AMWG meeting. 

2. Reclamation and USGS to continue to report updates related to monitoring and 

mitigation for dissolved oxygen conditions downstream of Glen Canyon Dam. 

Request that future “current condition” updates include temperature and DO 

thresholds for humpback chub. 

3. NPS asked for additional information regarding the Cultural Resources 

Monitoring (CRM) program. 

4. Grand Canyon River Guides (Ben and Zeke) asked to consider how the Adopt-ABeach surveys could complement or be integrated into existing monitoring 

programs. 

5. Several requests for consideration by the FLAHG and GCMRC regarding spring 

HFEs. There were questions during the modeling and flycatcher presentations. 

Can we have a discussion on the impacts of spring HFEs on flycatcher habitat 

and to discuss the questions that came up during the HFE modeling discussion? 

Can we also be sure to consider the impact of timing on the value of power 

production? There are different impacts depending on whether it is a spring or fall 

HFE. Could we have a full-day brainstorming about what we do and don’t know? 

6. Request for review and presentation related to GCMRC’s recent publication on 

the fate and transport of mercury. Request to include any information regarding 

for uranium mining around and water quality and quantity impacts through Grand 

Canyon? 

7. Administrative History Ad Hoc Group to review Paul Hirt’s completed website and 

report out at the October TWG meeting.
