Tests were conducted to determine 1 the magnitude of vibrations occurring at the dam structure, Vista House, and sluice gate, 2 gate-lip pressure fluctuations, 3 airflow rates, and 4 if correlation existed between the gate and Vista House vibrations. The measurements were made for a full range of gate openings at 1-ft increments from 1 through 10 ft with essentially full pool 799 ft msl. Data reduction and analysis by WES indicated a frequency correlation of small magnitude between the gate-lip pressures and Vista House vibrations during test 17 gate opening 9 ft. The measured air vent velocities and head losses were within the limits suggested by EM 1110-2-1602. The maximum air vent flow occurred when the sluice gate was fully open. Author
