Presently, Blue Mesa <br /> <br />storage releases are frequently made to maintain a 200 cfs flow in the 29- <br /> <br />mi Ie reach. <br /> <br />The principal water rights, the aggregated depletions, and the instream <br /> <br />water rights examined in the study are listed according to their water <br /> <br />right priority in Table 1. The water right priorities for instream flows <br /> <br />in the Black Canyon are varied in the study, and all variations of these <br /> <br />priorities are shown in Table 1. <br /> <br /> Table I: Water Rights Operated in Model <br />Model Rank Basin Rank Structure/Decletion Class Maximum Modeled Arnount <br />1 ( 5BB Upper Basin Seniors 3,720 af/yr <br />2 5BB Gunnison Tunnel Irrigation 1122 or 1300 cfs <br />3 (2052 Upper Basin Seniors 23,250 af/yr <br />4 2052 Taylor Park Storage 106,200 af/yr <br />5 (2937 Upper Basin Juniors 26,970 af/yr <br />6 Mid Basin Juniors 20,000 af/yr <br />7 2937 Blue Mesa Storage 952,202 af/yr <br />B (3223 Upper Basin Juniors 4,762 af/yr <br />9 Black Canyoy, Instream Flows <br /> 3223 P&M Donated 300 cfs <br />10 Wilderness Federally Reserved 600 cfs <br />11 )3223 Upper Basin Juniors 35,23B af/yr <br />12 Gunr.ison TUT.Tlel Power 900 cfs <br />13 Black Canyon Instream Flows 300 cfs or 600 cfs <br /> <br />A number of major water rights in the Gunnison River Basin were <br /> <br />reviewed in the study, but were not operated so as to simplify the model. <br /> <br />WBLA, Inc. 1909 Broadway, #3, Boulder, Colorado B0302 <br />
