<br />:; ,;-. <br /> <br />f. There may be trade-offs between reservo1r releases for <br />endangered f1sh spec1es and the hab1tat requ1rements of the <br />gold medal trout f1shery 1n the Fry1ngpan R1ver below Rued1. <br /> <br />3. Where - Rued1 1s somewhat d1stant from cr1t1cal hab1tat, so <br />effectlveness w1ll be m1n1mal unless water 1s part of an <br />exchange agreement to guarantee that 1t reaches target areas or <br />lnstream flows are decreed to the Colorado Water Conservat1on <br />Board. <br /> <br />4. Who - The Bureau mlght be able to set as1de some port1on of <br />Rued1 water or It mlght be possfble for water to be purchased by <br />other federal agencles or prlvate ent1t1es for use by endangered <br />flsh. Water rlghts for Ruedl are held by the Colorado R1ver <br />Water Conservat1on Dlstrlct. <br /> <br />5. When - Flows are avallable lmmed1ately subject to resoluHon of <br />the above lssues. <br /> <br />D. Curtall Plantlnq of Exot1c F1shes <br /> <br />1. Effectlveness - Exotlcs such as the northern p1ke appear to <br />occupy the same habltat n1che as the squawfish. Othllr specles <br />whlch may also be competlng for habitat include: channel <br />catfish. redside shlner, largemouth bass and the green sunflsh. <br />Results from USFWS research uS1ng tagged squawfish in locations <br />where exotlcs are present have provided overwhelm1ng evldence <br />that exotlc predators do eat squawfish. <br /> <br />The presence of exotic flsh also increases the risks from <br />predatlon and 4lsplacement for the humpback chub. <br /> <br />There do not appear to ,be major conflicts between trout and <br />endangered species. Trout do not travel the rlver or compete <br />for the same habitat. <br /> <br />Effectlveness of curtallment may be llm1ted because many specles <br />are already reproduclng In the system. It might be necessary to <br />eliminate establlshed populations of exotics. <br /> <br />2. Water lmoacts - Stocklng has been used as a mitigat10n measure <br />in the past. <br /> <br />3. Where - In the past, both the USFWS and DOW have stocked warm <br />water flsh and the State of Colorado continues to stock to <br />provlde fish for off-channel reservoirs and lakes. <br /> <br />stocking should be curtailed by all states 1n the Basin and the <br />USFWS. Stocking should be confined to instances of identlfied <br />need off the mainstem, where lack of conflict can be clearly <br />demonstrated ,in consultation with xhe USFWS. <br /> <br />- 8 - <br />
