Preparation for the meeting involved development of our presentation <br />materials, including a large folding map of the basin which we hope to be able to use throughout the <br />study, and rehearsals. We made a number of valuable contacts at the meeting with whom we are <br />pursuing follow-up discussions of water demands and reservoir sites. <br /> <br />Our work in Task 2 (Water Demands) focused on summarizing demand data from the literature <br />and conducting a number on in-basin interviews with agency representatives regarding water use and <br />development projections. I believe we have collected nearly all the "hard" information we will obtain <br />and are now doing a few final telephone interviews to insure that loose ends have been tied up. <br /> <br />Our work in Task 3 (Site Identification) focused on tabulation of the secondary information we <br />have obtained and pre-screening of sites. We have identified over 60 sites, roughly 25 of which meet the <br />criteria of being within 50 miles of Craig and having a potential capacity of no less than 10,000 AF. I <br />have compiled this information into tables which are being sent to a few knowledgeable basin residents <br />for verification/clarification. Based on their input and some generalized computations of inflows we will <br />be able to identify, on a preliminary basis, the sites we will propose for field reconnaissance. <br /> <br />We began work on Task 4 (Hydrology and Water Rights) in gathering data on streamflows and <br />diversions, We have also begun some statistical analyses the will permit us to estimate flows at ungaged <br />points and locations, up- or downstream from gages. <br /> <br />I anticipate that by the end of October we will be ready to propose water demand scenarios and <br />site recommendations for discussion with the TSC. Subsequent to those discussions we would finaljze <br />our proposals and develop materials for presentation of recommendations to the PAG. <br /> <br />cc: Bob Norman <br />,Sue Uppendah1 <br /> <br />anb:kjl <br />F:\SHARE\ TODO\MEM04.CRD <br /> <br />Hydrosphere 1002 Walnut Suite 200 Boulder, Colorado 80302 <br />
