<br />~ <br /> <br />l <br />~ <br /> <br />rf <br /> <br />\ The flow recommendations were selected to attempt to create channel bed conditions that are <br />theoretical habitat for the endangered fish based on two premises: (I) that the flows will create <br />the channel bed conditions and (2) the endangered fish will use the habitat. The habItat IS <br />measured by square meters and is monitored at least yearly. At the February 6, 2001 SJRBRIP <br />Biuiugy CUlIlIlliiit:c: lIiceting the follo"Y..ring 'vvas presented: (1) the habitat decreased 50~!t_1 ~fter the <br />1995 mnoff and has not recovered; (2) the amount of backwaters and islands are decreasing; (3) <br />the interstitial depth is decreasing; (4) flows above 5,000 cfs have not cleaned cobbles as <br />indicated in modeling; and (5) there is no linkage between habitat and biological response, <br />These troubling findings correspond to the decrease in numbers of endangered fish during this <br />period, As one of the Peer Reviewers for the SJRRIP commented at a Biology Committee <br />meeting "the relationship between mimicking a natural hydro graph and recovery of the fish is an <br />untested hypothesis", Further, the abundance of razorback suckers in Lake Mojave should <br />provide significant dOllbt concerning the need for mimicked flows to recover that species, <br />Based on the limited data to date, the hypothesis may not be true, <br /> <br />The EIS for reoperation of Navajo Dam is to "allow", not "meet", the Flow Recommendations <br />by providing for releases down to 250 cfs, <br /> <br />Adaptive Management (Chapter II, lines 297 to 303) is a component of the SJRBRlP, Is <br />Adaptive Management an "action" of the ElS? Or described in the EIS to reference the <br />SJRBRIP Adaptive Management program? The BO says Adaptive Management is an action of <br />the EIS, if so why have adaptive management programs in EIS and the SJRBRIP? Needs <br />clarification and consistency between EIS and BO. <br /> <br />The EIS presllpposes (Chapter II, lines 588 to 594) that water allocated but not used in the short <br />tenn will be used to provide releases from Navajo above 250 cfs. This water could also be used <br />for short term water development. The EIS should state that releases above 250 cfs are only one <br />possible llse of short ternl water. <br /> <br />The application of the Impact Indicators in Chapter III, Line 300 is a can ofwomls, Specifically <br />using shortages to NIIP and Navajo-Gallup as indicators is a problem when sh0l1ages to the Ute <br />Tribal Water Rights are not included as indicators, NIIP can have shortages and this shollld not <br />be used as an indicator. The Colorado Ute Water Rights Settlement is finalized just as the <br />Jicarilla Settlement and shollld be used as an indicator before Navajo-Gallup which does not <br />have valid approved water rights or environmental clearances, It does not appear that the <br />Navajo-Gallllp pipeline depletions are available within New Mexico and Arizona's Compact <br />allocations, A fifth indicator should be included for Colorado's Compact allocation, It appears <br />USBR is overly focused on Navajo-Gallup Pipeline to the exclllsion of other water users, the <br />purpose of the EIS is to allow the Flow Recommendations to benefit all water users in the San <br />Juan Basin, The indicators should address impacts to ALL water users or modified to remove <br />the bias. <br /> <br />SPECIFIC COMMENTS <br />Chapter I: <br /> <br />00817 <br />
