Summary
In 2017, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a large-scale interagency field study to determine the influence of commercial barge vessels on the efficacy of the Electric Dispersal Barrier System (EDBS) in the Chicago Sanitary and Ship Canal (CSSC) in preventing fish passage. This study included a series of trials in which a tow, consisting of a tug vessel and fully-loaded barges, transited the EDBS in both upstream-bound (n = 65) and downstream-bound (n = 66) directions. A 600 kHz Teledyne RDI Channel Master Acoustic Doppler Velocity Meter (ADVM), was mounted on the west canal wall at a depth of approximately 5.5 feet (1.7 meters), as measured on July 31, 2017 at 10:00 [...]
Summary
In 2017, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a large-scale interagency field study to determine the influence of commercial barge vessels on the efficacy of the Electric Dispersal Barrier System (EDBS) in the Chicago Sanitary and Ship Canal (CSSC) in preventing fish passage. This study included a series of trials in which a tow, consisting of a tug vessel and fully-loaded barges, transited the EDBS in both upstream-bound (n = 65) and downstream-bound (n = 66) directions. A 600 kHz Teledyne RDI Channel Master Acoustic Doppler Velocity Meter (ADVM), was mounted on the west canal wall at a depth of approximately 5.5 feet (1.7 meters), as measured on July 31, 2017 at 10:00 am CDT. The approximate elevation of the ADVM was 571.21 feet (NAVD88). The wall mounted instrument was located at (41.6423629, -88.060329). The provisional water surface elevation at the USGS streamflow gaging station on the Chicago Sanitary and Ship Canal ranged from 575.23 feet to 577.28 feet (NAVD88) over the study period (August 1 to August 11, 2017). The ADVM measured horizontal profiles of streamwise and cross-stream components of velocity in the 5 minutes of time prior to the tow entering the EDBS. During each trial the ADVM profiled nearly the entire width of the canal when no barges were located in the path of its acoustic beams (45 bins spaced by 1.0 meter starting 2.54 meters from the west wall). All velocity measurements represent an average of 10 pings, recorded every 17 seconds during measurement, and are included in this data release as Comma Separated Value (CSV) files. All time data is given in Central Daylight Time (CDT).

Purpose
Data were obtained to determine the influence of commercial barge vessels on the efficacy of the Electric Dispersal Barrier System (EDBS) in the Chicago Sanitary and Ship Canal (CSSC) in preventing fish passage.
