1986 and 1987) observed at the base of this structure. <br />Flaming Gorge Dam on the Green River and Glen Canyon Dam on the Colorado <br />River are located where some endangered fishes formerly occurred. Both of <br />these concrete dams are well over 500 feet high. Consideration for fish <br />passage at these type of structures would not be practical because of the high <br />cost to retrofit a passage facility to existing dams of these heights, and, <br />also, warmwater-endangered fish would likely avoid cold water releases from <br />such structures. <br />The Service has the support of the Colorado River Endangered Fishes <br />Recovery Team and the Colorado Water Conservation Board in pursuing fish <br />passage for recovering endangered fishes in the upper basin. <br />OBJECTIVES <br />Criteria are necessary for determining when and where fish passage would <br />be appropriate, and whether the use of such a facility would be an effective <br />means to aid recovery. Meeting or exceeding these criteria is a critical <br />component of the overall issue of fish passage and their possible role in <br />recovery of some of these fishes in the upper Colorado River basin. At this <br />time, these criteria have not been identified and have to be developed. <br />Fish passage: facilities have been identified in the Final Recovery <br />Implementation Program for Endangered Fish Species in the Upper Colorado River <br />Basin (Implementation Plan) as one of many possible recovery elements designed <br />ultimately to recover and delist the three endangerd fish species and to <br />manage the razorback sucker so it would not need the protection of the Act. <br />The Service recognizes that fish passage could be used for any one or a <br />combination of the four aforementioned endangered fishes in the upper basin. <br />The other three fishes are considered equally important as the Colorado <br />6
