\ ) -":} " Your November 1995 biological assessment determined that the test flow would have no effect on the endangered peregrine falcon (Falco peregrinus anatum), threatened bald eagle (Haliaeetus leucocephalus), and endangered razorback sucker (Xyrauchen texanus). Your determination removes these species from consideration because the action agency has the responsibility to determine "may effect;" consequently. the remainder of this biological opinion will not address those species. We do not concur with your determination that the test flow is not likely to adversely affect the humpback chub. While the long-term effect of the proposed test flow should be beneficial to the species, possible short-term adverse affects need to be evaluated. The consultation also analyzes new information made available regarding the J(anab ambersnail. > ~ ~. On December 14, 1995, the Service requested additional information on potential impacts to the southwestern willow flycatcher which Reclamation provided in a draft supplemental repon dated January 8, 1996. On January 23, 1996, our staffs met to review the data and concluded that the test flow is likely to adversely affect habitat of the southwestern willow flycatcher. Your February 1, 1996, memorandum requested the Service to include the southwestern willow flycatcher in the ongoing formal consultation. Because your memorandum identified possible adverse modification of southwestern willow flycatcher habitat, we included a conference opinion on that species' proposed critical habitat. i", ,'" ~i; ~' :-j ,..,~ SUMMARY BIOLOGICAL AND CONFERENCE OPINIONS , ;:;: After reviewing the current status of the humpback chub, Kanab ambersnail, and southwestern willow flycatcher, the environmental baseline for the action area, the effects of the proposed spring 1996 beach/habitat-building flow from Glen Canyon Dam (test flow), and the cumulative effects, the Service's biological opinion is that the test flow, as proposed, is not likely to jeopardize the continued existence of the humpback chub, Kanab ambersnail, and southwestern willow flycatcher, and is not likely to destroy or adversely modify designated critical habitat for the humpback chub. t~ ,. rr \ \.:' '.", ~.

Critical habitat for the Kanab ambersnail has been proposed only in Utah; however, this action does not affect that area and no destruction or adverse modification of that critical habitat is anticipated. ;..,0 j':;:" :_,/ ( t-~ ~.~: I. ::F ~~ ~, f~1 (,~ ~.~1 !S~: CONSULTATION mSTORY This reinitiates consultation on the preferred alternative for the FEIS that resulted in a final biological opinion dated December 21,1994, transmitted to Reclamation January 7, 1995 (1995 biological opinion).
