In addition, single transducer sounding techniques or multi-transducer sweeps, or both will perform these surveys. Bottom Soundings will be calibrated daily by the bar or ball-check method or sound velocity profiler to account for variations of speed of sound in water. Project Environmental Window: All dredging (hydraulic and bucket) is restricted during the period between April 1 and June 15 annually in order to minimize impacts to migratory fish.(d) The Pedricktown North Disposal Area will be made available for the disposal of all dredged material removed by this contract work.
