Abstract: A 1:25-scale model simulated two 35-ft-wide by 18-ft-high tainter gates with a 19-ft radius, three 6-ft-wide piers, a 5.27-ft-long apron, a schematic of the pumping station and fore-bay intakes on the right, the existing log boom posts upstream of the fore-bay intakes, the turnpike bridge, the remaining 160-ft-long section of the existing fixed ogee spillway on the left and a 38-ft-long section of the existing fixed ogee spillway on the right of the proposed structure, 300 ft of the upstream approach, and 600 ft of the exit channel including a section of the channel extending 100 ft downstream of the turnpike bridge. Discharge characteristics and coefficients with various operating scenarios were determined. Flow patterns and velocities measured in the model indicated that the approach flow conditions were satisfactory, while some modification of the energy dissipator was necessary to spread the flow exiting the structure. Preconstruction conditions were compared with conditions that developed from the proposed structure. Scour potential was also determined downstream of the structure. Fish and aquatic habitation criteria for velocities were met.
