Velocity Survey at Cross Sections in the Illinois River below Starved Rock Lock and Dam near Utica, Illinois, June 16, 2021

In support of U.S. Geological Survey invasive carp research examining aggregations of invasive carp in the tail water of dams, water velocity measurements were made at cross sections in the Illinois River below Starved Rock Lock and Dam on June 16, 2021. A total of 16 cross sections were surveyed, with two transects per cross section. Water depth and crew safety limited the extent of the survey. The discharge in the Illinois River at Starved Rock Lock and Dam at the time of data collection was approximately 185.7 cubic meters per second. The data were processed in the Velocity Mapping Toolbox (VMT) v.4.09 (Parsons and others, 2013) to obtain a depth-averaged velocity field for each cross section from paired transects...

Water Temperature and Specific Conductance in the Chicago Sanitary and Ship Canal Near the Electrical Dispersal Barrier System at Romeoville, Illinois, October 1, 2017, to September 30, 2018

Water temperature (degrees Celsius) and specific conductance (microsiemens per centimeter at 25 degrees Celsius; TC) were measured at U.S. Geological Survey streamgage 05536995, located at Chicago Sanitary and Ship Canal near the Electrical Dispersal Barrier System in Romeoville, Illinois. The TC data were measured every five minutes at four gage height levels above the gage datum (P1 = 21 feet, P2 = 17 feet, P3 = 13 feet, P4 = 9 feet). The gage datum is 551.76 feet above the North American Vertical Datum of 1988 (NAVD 88). Daily mean and five-minute water temperature and specific conductance data were downloaded from the National Water Information System (NWIS) database and stored in Comma Separated Values (CSV)...

Summary of the Characteristics of Near-Surface Flow Reversals at the Electrical Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2017, to September 30, 2018

This dataset contains a summary of the characteristics of near-surface flow reversals at the Electrical Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal at Romeoville, Illinois during Water Year 2018 (October 1, 2017, to September 30, 2018). Water velocity near the water surface is measured on a five-minute sampling interval in the EDBS using surface velocity radar at nine measurement cells on a cross section near U.S. Geological Survey streamgage 05536995 (Chicago Sanitary and Ship Canal at Romeoville, Illinois). Flow reversal events are analyzed for each individual cell as well as for the average velocity over all nine cells. For the analysis of individual cells, a flow reversal event is...

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, over the period 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...

Discharge measurements at U.S. Geological Survey streamgage 05536890 Chicago Sanitary and Ship Canal near Lemont, Illinois, 2005-2013

Discharge measurements made at U.S. Geological Survey Chicago Sanitary and Ship Canal near Lemont, Illinois, streamgage (05536890) between 2005 and 2013 were reviewed and manually processed using QRev v3.12. Discharge was measured using Acoustic Doppler Current Profilers (ADCPs) deployed from a moving boat according to the procedures described in Mueller and others (2013). QRev generates an extensible markup language file (XML) that provides information on measurement characteristics (Mueller, 2016a,b). Data from these XML files were exported into a comma-separated values (CSV) table to create a summary of measurement information. This CSV table also indicates which measurements were used in the development of index-velocity...
