These data were collected using a 1200 kHz TRDI Rio Grande acoustic Doppler current profiler (ADCP) in mode 12 with 25 centimeter bins from a moving boat. The data were georeferenced with a Hemisphere Crescent A100 differential Global Positioning System (GPS) receiver with submeter accuracy. The data have been depth-averaged over the entire measured portion of the water column and temporally averaged over 5-second intervals to reduce noise. These data were collected by the U.S. Geological Survey (USGS) concurrently with environmental DNA (eDNA) sampling in this reach of the Chicago Sanitary and Ship Canal (CSSC) by the U.S. Fish and Wildlife Service (USFWS). Data were processed using the Velocity Mapping Toolbox...

These data were collected using a 1200 kHz TRDI Rio Grande acoustic Doppler current profiler (ADCP) in mode 12 with 25 centimeter bins from a moving boat. The data were georeferenced with a Hemisphere Crescent A100 differential Global Positioning System (GPS) receiver with submeter accuracy. The data have been layer-averaged over the lower portion of the water column (0 to 4 meters above the bed). These data were collected by the U.S. Geological Survey (USGS) concurrently with environmental DNA (eDNA) sampling in this reach of the Chicago Sanitary and Ship Canal by the U.S. Fish and Wildlife Service (USFWS). Data were processed using the Velocity Mapping Toolbox (Parsons and others, 2013). NOTE: Any data assigned...

In 2016, 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 six fully-loaded barges, transited the EDBS in both upstream-bound (n = 23) and downstream-bound (n = 22) directions. A 1,200 kHz Teledyne RDI Channel Master Acoustic Doppler Velocity Meter (ADVM) was mounted on the barge at the position of the rake-to-box junction. The ADVM faced outward from...

This study included a series of trials in which a tow, consisting of a tug vessel and six fully-loaded barges, transited the EDBS in both upstream-bound (n = 23) and downstream-bound (n = 22) directions. A 3,000 kHz SonTek Argonaut SW Acoustic Doppler Velocity Meter (ADVM) was mounted on the barge at the position of the rake-to-box junction. The ADVM faced outward from the side...

A dye tracer study was completed on the lower Sandusky River between July 11-13, 2017, during a confirmed Grass carp (Ctenopharyngodon idella) spawning event. The data contained in this data release include time series of dye concentration at fixed stations downstream of the injection site. Six submersible fluorometers (Turner Designs C3TM fluorometers) were deployed at predetermined stations between 1.19 and 16.05 river miles downstream of the injection point on July 10, 2017, approximately 24 hours prior to the injection. The fluorometers were mounted atop cinder blocks and deployed in approximately 3 to 4 feet of water with good circulation. The instruments were secured to shore using safety lines. The fluorometers...
