' Glen Canyon Dam Technical Work Group Page 2 <br />DRAFT Minutes of July 16 -17, 2008, Meeting <br />' Action Item 2007:06.25 -26(4) John Hamill expressed concern about the process and how to get projects <br />through the process that doesn't involve the TWG. He feels there needs to be some resolution to the <br />process. Dennis said that the full TWG looks like they're not performing because the ad hoc groups aren't <br />completing their work or providing information to the TWG. He plans to make revisions to the MRP <br />addressing issues from the biological opinion and proposals to the MRP. Mary Barger recommended <br />GCMRC set up a meeting at GMCRC for TWG members who are interested to discuss the issues. She <br />' feels the comfort level would go up with those issues resolved or elevated. <br />Kurt said that he John Hamill, John O'Brien, Dennis Kubly, and himself would meet sometime during this <br />meeting to figure out how to get that issue resolved and report back to the TWG tomorrow. Kurt also said <br />he and Dennis will talk about how to make ad hoc groups more effective. <br />1 OLD BUSINESS: None. <br />New Business: Nomination of TWG Chair. Dennis asked the members to think of people they'd like to see <br />be nominated. They should provide names to Dennis or Linda. <br />FY09 Budget and Work Plan & Updates. Kurt said at the last TWG meeting, a series of nine issues were <br />identified and hopefully during the past BAHG conference calls those specific issues were identified and <br />' dealt with. It's his plan the TWG will review those and then focus the discussion on new projects. <br />Socio Cultural Program Update. Helen Fairley said the only new project is under Goal 9 (line 103), <br />"Compile and Analyze Existing Safety Data." A graduate student will be analyzing the data and develop an <br />assessment of their knowledge of safety issues. In response to Dennis' question as to whether a <br />comparative study was done, Helen said a 1996 study was compiled by Larry Stevens as part of a <br />published book. Helen also said she has information on the R &D program and left copies on the table <br />' (Attachment 2). <br />Physical Science Update. Paul Grams, the new physical scientist manager at GCMRC, said he was going <br />' to focus on what they see as new initiatives in physical science and modeling. He said a lot of these were <br />presented in great detail at the last TWG meeting especially with regards to the issue of modeling, but he <br />wants people to really understand what projects are falling under Goals 7 and 8. He said projects fell into <br />two different categories: 1) things directed to sediment accounting and the sediment bank account, the <br />mass volume of sand they're working with, movement downstream, export to Lake Mead, and the tracking <br />of the resources, and 2) activities directed to sand and sediment monitoring and keeping track of things that <br />people care about. <br />He thought people were probably familiar with sand mass balance so he didn't want to go into those details <br />but stated there are real time measurements and sampling going on. The ideal is to measure the storage <br />and measure it repeatedly. It's not technically possible to map the entire bathymetry of the system and it's <br />not just mapping but making the changes from one measurement to another in a given segment of river. <br />Next year from Lee's Ferry to River Mile 30 they will have a measurement from storage between two points <br />and putting together the whole sediment budgeting process. The sediment trend is the complete mapping <br />from Lee's Ferry to River Mile 30. They will be able to do comparisons between what was done last year <br />and this year. This is really moving into a long -term monitoring issue. <br />The other new initiative is directed toward modeling. While monitoring helps them to keep track of where <br />they are, the modeling also helps them design the appropriate duration and exact timing and peak of flow <br />events and compare them with the rest of the year and also look at different operation strategies. <br />Vegetation Classification Update. Matthew Andersen updated the TWG on a report Barbara Ralston <br />' developed and said he brought a few copies of the open file report, "A Vegetation Database for the <br />Colorado River Ecosystem from Glen Canyon Dam to the Western Boundary of Grand Canyon National <br />11 <br />
