Meager anticipated snowmelt runoff is expected to mean another challenging year for maintaining even below-optimal levels of flows in the Colorado River downstream of the Palisade area for the benefit of endangered fish. … What’s referred to as the 15-Mile Reach of the river between the Palisade area and the Gunnison River confluence is of particular concern for the Upper Colorado River Endangered Fish Recovery Program, which focuses on four endangered fish. The stretch is primarily used by two of the fish — the razorback sucker and Colorado pikeminnow. But it’s also used by a third, the bonytail. And a fourth, the humpback chub, which favors downstream stretches such as Westwater Canyon, indirectly benefits from efforts to bolster flows in the 15-Mile Reach.
