<br />, <br /> <br />and winter is higher than that during spring. Potential dollar losses have <br />not been fully assessed. <br /> <br />Asoinall Unit <br /> <br />Section 7 on the Aspinall Unit is still in the early study phase. Questions <br />relating to timing and volume of flow have not been addressed although target <br />flows in occupied habitats in the Colorado have been recommended which suggest <br />that flows may need to be returned to a more natural hydrograph. This would <br />include high flows in spring and stable low flows in summer and winter. Power <br />production should not be impacted greatly since Crystal is are-regulatory <br />structure and power is produced as a flow through or run of river system. <br />Earlier research in the Gunnison River system pointed to temperatures as a <br />potential problem for the mainstem endangered fishes.. Water volumes, <br />temperatures, and other related factors will need to be studied before any <br />I <br /> <br />recommendations can be made on the protection of listed fishes in the <br />Gunnison/Colorado Rivers. Study flows will be recommended which can then be <br />correlated with squawfish and razorback reproductive and recruiting success. <br /> <br />Nava.io <br /> <br />Recent events in southwest Colorado related to the construction of the An1mas- <br />LaPlata project have focused attention on the presence of Colorado squawfish <br />and razorback sucker in the San Juan River. Continued negotiation on an MOU <br />and a Recovery Implementation Program for the San Juan River fishes ;s almost <br />a daily affair in our regional and field offices. The draft biological <br />opinion for ALP calls for 300.000 AF of water to be made available to the fish <br />
