None supplied. From executive summary: The Redlands Dam passageway, constructed on the Gunnison River, a major tributary of the Colorado River, near Grand Junction, Colorado, was completed in 1996. The first of its kind in the Upper Colorado River Basin, its specific purpose was to provide upstream passage for two Federally listed fishes, the Colorado pikeminnow and razorback sucker. It was also designed for selective passage. That is, it was to preclude upstream movement of nonnative fish. The purposes of this investigation were to (1) evaluate whether sub-adult and adult Colorado pikeminnow would use the fish passageway at Redland Dam and (2) monitor movements and distribution of Colorado pikeminnow that pass through the fish passageway.
