Observe vessels passing inland-waterway checkpoint.
What does a Waterway Traffic Checker do?
Observes vessels passing inland-waterway checkpoint, using binoculars, to verify identity and ascertain speed and direction. Telephones observations to designated control point, such as drawbridge or lock station. Reports movements of overdue vessels to estimate arrival time at specified points along waterway. Notifies waterway officials or other authorities of accidents, distress signals from passing vessels, obstructions, and other unusual conditions observed from checkpoint. Records observations in log.
