Monitoring data to support the operation of the Electric Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2017, to September 30, 2018

The U.S. Geological Survey monitors water surface flow reversals, commercial vessel traffic, and temperature and specific conductance in the U.S. Army Corps of Engineers Electric Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal, Chicago, Illinois. This data release is the 2018 water year summary of the EDBS monitoring data. Water surface flow reversals at the EDBS are monitored using surface velocity radar. Commercial vessel traffic patterns through the EDBS are documented using a motion-activated video camera. Temperature and specific conductance are reported in near real-time from USGS sensors installed just downstream of the EDBS.
