<br />Section 2 <br />Reports From Basin Roundtables <br />II11 <br /> <br />The Management Plan for Endangered Fishes in the <br />Yampa River Basin assists in the recovery of four <br />endangered fish species as water depletions from the <br />Yampa River Basin continue to serve human water <br />needs in Colorado and Wyoming. The plan recommends <br />that daily average base flows in the Yampa River not fall <br />below 93 cfs at Maybell from August through October at <br />any greater frequency, magnitude, or duration in the <br />future than had occurred historically. Uncertainty with <br />respect to the winter flow needs of the fishes prompted <br />the US Fish and Wildlife Service to extend the base flow <br />period through the winter months with a 33 percent buffer <br />added to the 93 cfs flow target (i.e., 124 cfs) during this <br />period, which is consistent with observed hydrologic <br />patterns. The plan proposes to augment base flows in <br />accordance with these recommendations to compensate <br />for impacts to base flows due to depletions. Hydrologic <br />modeling demonstrated that 7,000 AF would satisfy base <br />flow needs in all but the driest years. <br /> <br />2-18 <br /> <br />Numerous instream flow rights have been decreed on <br />major rivers and tributaries in the Yampa/White/Green <br />Basin, which can be found at <br />http://cwcb.state .co. us/Streamand lake/Database/. <br /> <br />S:\IBC Support\Report to Legislature\Section 2 finaLdoc <br />
