Importance. The mainstem Colorado River from Rifle, Colorado, to Lake Xxxxxx, Utah, supports populations of humpback chub and Colorado pikeminnow, and is recognized as important to the recovery of all four endangered fishes (U.S. Fish and Wildlife Service 1990a, 1990b, 1991, 1998, 2002a, 2002b, 2002c, 2002d). Relatively large and healthy humpback chub populations occur at Black Rocks and Westwater Canyon near the Utah-Colorado state line. A smaller humpback chub population occurs in Cataract Canyon, and some of the last wild bonytail were collected in this river reach. All life stages of Colorado pikeminnow occur in the section of river from Palisade, Colorado, downstream to Lake Xxxxxx. Colorado pikeminnow have been translocated and stocked into the upper reach of the Colorado River between Palisade and Rifle, Colorado; natural access to this historic-habitat reach has been blocked since the early 1900's by three diversion dams near Palisade. Razorback sucker populations in the mainstem Colorado River have declined precipitously in the past 20 years. In 1993, 67 adult razorback sucker were collected from isolated ponds adjacent to the Colorado River near Debeque, Colorado. Since then, only a few wild adult razorback sucker have been captured from the river.

In 1993, 67 adult razorback sucker were collected from isolated ponds adjacent to the Colorado River near Debeque, Colorado. Since then, only Only a few wild adult razorback sucker have been captured from the riverriver in the past 5 years, and there is no evidence of successful reproduction in the Colorado River. A few (less than 10) suspected wild bonytail have been captured from the Colorado River in the Black Rocks area, near Moab, Utah, and in Cataract Canyon over the past decade. However, this represents the highest catch rate of bonytail anywhere in the Upper Basin.
