This file contains records of all the empty barges for the selected Rivers and locks. The data is from the US Army Corps of Engineers, Lock Performance Monitoring System.

This dataset contains numbers of monthly empty barge movements including the following five rivers: Mississippi River (3 locks), Illinois River (2 locks), Ohio River (2 locks), Arkansas River (2 locks), and Columbia River (2 locks). Both upbound and downbound traffics are included.

USDA/AMS also published a weekly empty barge dataset for Mississippi River, Illinois River, and Ohio River titled "Upbound and Downbound Loaded and Empty Barge Movements (Count)", which contains data for one lock in each river.
