<br />. Cooperative Instream Flow Service Group, but was not a member of the <br />Steering Committee. <br /> <br />..... <br />...., <br />l'Y <br />--.l <br /> <br />At the December 21 meeting, the CIFSG gave a presentation of the concepts <br />behind the methodology and an enumeration of the data requirements <br />necessary to make the model work. Mr. Frank Davenport, WRC made two <br />points: (1) WRC doesn't expect a sophisticated water allocation model <br />for the whole basin to come out of the assessments, but does expect some <br />indication of the volumes of water that are "conflict-free" after consid- <br /> <br />ering instream flows as well as consumptive uses; and (2) the assessments <br /> <br /> <br />should operate on a "what if" basis - for example, if certain volumes of <br /> <br /> <br />water were consumed, what would be the likely effect on fisheries? <br /> <br />. B. Riverine Analysis Areas (RAA's) in UCRB <br /> <br />From figure 2 it will be seen that only two RAA's are involved in the <br /> <br /> <br />UCRB. They are 14A and 14B. RAA 14A has cold-water fish habitat, where- <br /> <br /> <br />in average warm-weather water temperatures do not exceed 700F (210C). RAA <br /> <br /> <br />1DB is a cool-water area wherein summer air temperatures do not raise <br /> <br /> <br />average water temperatures above 8DOF (26.50C). This is reflected in the <br /> <br /> <br />species of fish present in each area. Where a watershed lies partia11y <br /> <br /> <br />in A and partially in B, there will be a transition zone in which cold <br /> <br /> <br />and cool water species may be found, and this fact influenced the selec- <br /> <br /> <br />tion of target species. <br /> <br />. <br /> <br />15 <br />
