17 known locations for genetic analyses and development of discrete brood stocks if necessary. These measures have been undertaken to develop refugia populations of razorback sucker from the same genetic parentage as their wild counterparts such that, if these fish are genetically unique by subbasin or individual population, then separate stocks will be available for future augmentation. Such augmentation may be a necessary step to prevent the extinction of razorback suckers in the Upper Basin. Habitat requirements of young and juvenile razorback suckers in the wild are largely unknown, particularly in native riverine environments. life stages, other than adults, have been extremely rare in the upper basin in recent times. One confirmed capture of razorback sucker juveniles in the upper basin was in the Colorado River near Moab, Utah (Taba et al. 1965). The only capture in recent years was the 1991 collection of two early juvenile razorback suckers in the lower Green River, 89.5 km above the confluence with the Colorado River (Gutermuth et al. 1994). Razorback Sucker Activitv: San Juan River Because razorback sucker are so rare in the San Juan River and spawning or recruitment has not been documented, an experimental stocking program was initiated. In March of 1994, 15 radio-tagged razorback sucker were stocked in the San Juan River at Bluff, Utah (river mile 79.6); near Four Corners Bridge (river mile 117.5); and above the Mixer in New Mexico (136.6). In November of 1994, at these same locations plus at an additional site just below the Hogback Diversion in New Mexico (river mile 158.5), an additional 15 radio-tagged adults and 656 PIT-tagged fish were stocked. Monitoring found that these razorback suckers used slow or slackwater habitats such as eddies, pools, backwaters, and shoals in March and April and fast water 92.2 percent of the time in June and August (Ryden and Pfeifer 1995b). During 1995 both radio-tagged fish and PIT-tagged fish were contacted or captured. Razorback suckers were found in small numbers from the Hogback Diversion (river mile 158.6) to 38.1 river miles above Lake Powell (Dale Ryden, USFWS, pers. comm.) Critical Habitat Critical habitat has been designated within the 100-year floodplain of the razorback sucker's historical range in the following section of the San Juan River Basin (59 FR 13374). New Mexico. San Juan Countv: and Utah. San Juan Countv. The San Juan River from the Hogback Diversion in T. 29 N., R. 16 W., section 9 to the full pool elevation at the mouth of Neskahai Canyon on the San Juan arm of lake Powell in T. 41 S., R. 11 E., section 26. BALD EAGLE Status On August 11, 1995, the bald eagle was reclassified as a threatened species (60 FR 36000) in the conterminous United States where it was previously listed as endangered (every state except for Washington, Oregon, Minnesota,
