Upbound and Downbound Loaded and Empty Barge Movements (Count)

internal.agtransport.usda.gov | Last Updated 26 Mar 2020

This dataset provides weekly information on the number, location, direction, and type of barges transiting the following three major points: (1) the last lock on the Mississippi River, Mississippi Locks 27 (called "Miss Locks 27" in the dataset); (2) the last lock on the Ohio River, Olmsted Locks and Dam ; and (3) the last lock on the Arkansas River, Arkansas River Lock and Dam 1 (called "Ark Lock 1" in the dataset). (Olmsted locks replaced Ohio Locks 52 beginning in November 2018.) The data offers insight on barge movements over time. One variable is "direction", which consists of upbound ("Up") and downbound ("Down"). It also offers insight on the "type" of traffic (e.g., empty barges, loaded barges, grain barges, and non-grain barges). More specifically, upbound data includes the number of empty barges and the number of loaded (any commodity) barges transiting the locking system. Downbound data includes the number of empty barges, the number of grain barges (loaded), and the number of non-grain (loaded) barges. That is, grain and non-grain sum to total loaded for downbound traffic. will Due to data availability, prior to 10/15/2000, downbound data includes just empty and loaded counts. A similar dataset, "Downbound Barge Grain Movements (Tons)," contains information on the tonnage (and commodity) of grain moving by barge down the locking system: https://agtransport.usda.gov/d/n4pw-9ygw/. Data is collected weekly from the U.S. Army Corps of Engineers' Lock Performance Monitoring System.

This dataset has the following 8 columns:

Column NameAPI Column NameData TypeDescriptionSample Values
Datedatecalendar_dateWeek ending date. For example, a date of January 7 means the number of barges spans January 1 to January 7.
WeekweeknumberWeek number calculated from the reported week ending date (Date field). Week 1 is the first week of the year with a week ending date falling on or after January 4. In other words, it is the first reported week of data which includes four days in the new year. Values range from 1 to 52 or 53, depending on the year.
MonthmonthnumberMonth number calculated from the reported week ending date (Date field). Week ending dates falling before the fourth day of the month are assigned to the previous month. For example, a week ending date falling on February 1st, 2nd, or 3rd would correspond to “1” (January), since there are less than four days in the reported week that fall in February. Values range from 1 through 12, where 1 refers to January, 2 to February, etc.
YearyearnumberYear number calculated from the reported week ending date (Date field). Week ending dates falling on or after January 4 correspond to the calendar year of the reported week. Week ending dates falling on or before January 3 correspond to the previous calendar year. For example, a week ending date falling on January 2, 2018 would be “2017.” Values range from 2005 to the present.
LocklocktextOne of three selected locks: Mississippi Locks 27 ("Miss Locks 27"); Ohio Olmsted Locks and Dam ("Ohio Olmsted"); and Arkansas River Lock 1 ("Ark Lock 1").
Directiondirectiontext"Up" for upbound; "Down" for downbound.
TypetypetextThe type of barge transiting the lock (e.g., "Empty," "Loaded," "Grain," "Non-Grain Loaded"). Type varies by Direction field.
Barge Countbarge_countnumberThe number (or count) of barges of a certain Type transiting a Lock location.
