Summary of the Characteristics of Commercial Tows Passing Through the Electrical Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2018, to July 3, 2019

A motion-activated video camera documented the passage of commercial tows through the Electric Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, during Water Year 2019 (October 1, 2018, to July 3, 2019). Videos were manually screened and analyzed to extract tow characteristics including date and time of video recording, number and configuration of barges, loading of barges (loaded, unloaded, or mixed), direction of travel, and bow type (rake or box). Only commercial vessels were logged and no identifying data about the tow vessels were maintained. All videos triggered by recreational vessels or other objects were permanently removed from the database during analysis. Any periods of missing data due to instrument malfunction were documented in the metadata. Video logs for each month are provided as comma separated value fileds for stored in a zipped folder named 05536995-WY2019-videologs.zip.
