Abstract: A 1:20 Froude-scale physical model study of three proposed fish-passage structures for Price-Stubb Diversion Dam was conducted at the Bureau of Reclamation’s Water Resources Research Laboratory in Denver, Colorado. This study was conducted to provide hydraulic performance information and demonstrate proof-of-concept for the recommended fish passage structure. The results indicate that a notch in the diversion dam and a downstream 1.5 percent rock channel along the left bank is sufficient to allow adequate passage for the Colorado pikeminnow and razorback sucker, each an endangered fish species, for Colorado River discharges ranging from 640 cubic foot per second (ft3/s) up to approximately 30,800 ft3/s. For all cases tested, average mid-depth velocities were found to be between 3.0 foot per second (ft/s) to 8.0 ft/s. Application of the universal velocity profile analysis for a completely rough boundary shows that the turbulent boundary layer is expected to produce velocity zones below approximately 2.0 ft/s within a distance of 0.75-foot from the boundary. Such results are expected to produce efficient passage conditions based on field and laboratory experience, swimming ability of the target species, and behavioral characteristics of the target species.
