The representative from Bureau of Reclamation . Navajo Dam <br />Operations; shall meet with the Biology committee in January to present <br />infonnation on the projected water availability of the current water year (T <br />April- 30 November) and storage capacity of Navajo Reservoir. The Biology <br />Conunittee shall develop the desired criteria for releases for the current water <br />year (April through November) under the oversiaht of the Conrdination <br />Committee. . . . <br /> <br />5. Reclamation shall cooperate with the Biology Conunittee and Navajo Dam <br />Operating Committee to determine the release hydrograph for spring flows <br />and shall follow the agreed upon hydrograph without deviation, except under <br />emergency conditions, indlldinQ' hilt not limited to, an ablUnt and <br />unanticipated chan~ in hydroloaic conditinns where deviation is required to <br />stay within the Corps of Engineers' flood operating rules or where 8lrreed <br />llpnn by the Service and Reclamlltinn. <br /> <br />4. C.nmmp.nt: Page 3, Element 6: Year-round flow recommendations should be flexible enough <br />to address wide variations in hydrologic conditions and the needs of the fish as determined <br />from additional knowledge. The requirement for such flexibility needs to be clearly stated. <br /> <br />S.

However, <br />even this smaller depletion is biologically acceptable only if all elements of the <br />reasonable and prudent alternative are fblly implemented. Therefore, Phase <br />I, Stage A could not exceed 57,100 acre-feet of deplp.tinns until all elements <br />of the RP A are fully implemented. This would require that Reclamation <br />operate Navajo Dam duriniJ the research pp.rind to provide the flexibility to <br />mimic a natural hydrograph as directed by the Biology Committee under the <br />oversiiht nfthp.
