SUBJECT:: Biologiesl Opinion - Stagecoach Reservoir Project

Following is the U.S. Fish and Wildlife Service's (the Service) biological
opinion for the Stagecoach Reservoir Project (the Project). Reference is made
to your .emorandum to the Service dated May 29; 1985, which transmitted a
biologic$l assessment (Bureau of Reclamation. 1985) for the Project. Although
yonr ass~ssment came to the -no effect- determination for federally listed
species, ithe Service believes that the effects of your Federal action wa=ant
the -may Jaffect- determination for--'Certain life stages of endangered Colorado
Uver ba~in fishes which inhabit Yalllpa Uver reaches dovnstrealll from the
reservoir site. The Service also believes that the proposed action -may
affect- ~he Bald Eagle (Haliaeetus leucocephalus). Therefore, on July 3,
1985. th. U. S. Bureau of Rec:1a_d.on (the Bureau) initiated formal Endangered
Species 4ct (ACT) Section 7 cOlUlultation with the Service. We sgree with your
-no effe~t- determination presented in the biological assessment for the
blac:k-fodted fe=et (Mus tela nigripes). This opinion has been prepared as
prescri~d in the Section 7 Interagency Cooperation Regulations. 50 CFR 402,
and the ACT, 16 U.S.C. 1531.!!.!.:..~.

The 9o-d~y formal consultation period was extended by mutual agency agreement
until Nov,ember 1. 1985. as outlined in a Service memorandum to the Bureau
dated Juiy 23. 1985. Subse4uently. a 30-day extension was requested by the
Service .emo dated January a. 1986, and agreed to by the Bureau memo dated
January ~3, 1986. Unforeseen difficulties in developing conservation measures
made ano~her extension necessary. which was requeated by the Service memo
dated Fe~ruary 12, 1986. The last day for formal consultation was established
by the Bdreau (memo dated June 13, 1986) as June 27, 1986.
