Data

A Turner Designs C3 submersible fluorometer was deployed in the Brandon Road Lock chamber (BRLD) near Rockdale, Illinois, to measure Rhodamine WT dye concentrations during a U.S. Geological Survey dye study conducted on October 20, 2015. The lock chamber at BRLD was dyed with 4 liters of Rhodamine WT dye during a routine filling procedure. Measurements of dye concentration profiles were collected

An Insitu Level Troll 500 was deployed in the Brandon Road Lock chamber (BRLD) near Rockdale, Illinois between 12:09 Central Daylight Time (CDT) on October 19, 2015 and 14:57 CDT October 21, 2015 to monitor water-surface elevation in the lock chamber during a U.S. Geological Survey dye study conducted on October 20, 2015. The duration of the deployment included a day prior to and a day following t

Five Turner Designs C3 submersible fluorometers were deployed in the Des Plaines River downstream of the Brandon Road Lock and Dam (BRLD) near Rockdale, IL, to measure Rhodamine WT dye concentrations during a U.S. Geological Survey dye study conducted on October 20-21, 2015. The lock chamber at BRLD was dyed with 4 liters of Rhodamine WT dye during a routine filling procedure. Measurements of dye

Two survey boats equipped with differential Global Positioning System (GPS) receivers and Turner Designs C3 submersible fluorometers were used to survey the spatial distribution of the Rhodamine WT dye in the Des Plaines River downstream of the Brandon Road Lock and Dam (BRLD) near Rockdale, Ilinois. Mapping of the dye plume commenced after the lock chamber at BRLD was dyed with 4 liters of Rhodam

Water velocities were measured in the Des Plaines River from approximately river mile 286 to river mile 284 on October 1921, 2015 using Teledyne Rio Grande 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. These velocity data were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi

Water velocities were measured along the Illinois and Des Plaines Rivers using a Teledyne Rio Grande 1200 kHz acoustic Doppler current profiler (ADCP). ADCP data were collected in reciprocal pairs along crosssections and along approximately streamwise-oriented lines between crosssections at the following locations: (1) the Dresden Island Pool of the Des Plaines River on May 14, 2013 and July 3

On August 31, 2015, USGS Illinois Water Science Center staff deployed a 2000 kHz side-looking acoustic Doppler velocity meter (ADVM) in the Chicago Sanitary and Ship Canal (CSSC) at the Electric Dispersal Barrier System (EDBS). These data were collected as a fully loaded commercial barge tow traversed the EDBS and passed the ADVM three times, and as several smaller vessels and an unloaded barge to

Water velocities were measured in the Calumet Harbor for 5 dates in 2015 and 2016 using Teledyne Rio Grande 600 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. These velocity data were collected in cooperation with the US Army Corps of Engineers-Chicago District. ADCP data were collected on the following dates:

These data files include georeferenced water-quality data with associated time stamps (Central Standard Time) for basic water-quality parameters as measured by a towed multiparameter sonde (YSI 6920 sonde) from a manned boat in the Chicago Sanitary and Ship Canal. Data were collected on February 25-27, 2010, and again on March 2-3, 2010. The data collected in February 2010 had the sonde on a fixed

Water velocities were measured in the Chicago Sanitary and Ship Canal (CSSC) in 2010 and 2011 using Teledyne Rio Grande 600 kHz and 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. Data were processed using the Velocity Mapping Toolbox (Parsons et al., 2013). Any data assigned a value of "-9999" are bad or missi

In August 2015, water velocities around a fully-loaded commercial barge tow were measured as the barge tow traveled upstream through the Chicago Sanitary and Ship Canal from a starting position in Lockport Pool, and passed through the Electric Dispersal Barrier System at river mile (RM) 296 near Romeoville, IL. Velocity measurements were made in and alongside the gap formed by the junction between

These data were collected during a dye tracing study of the lower Des Plaines River and lower Chicago Sanitary and Ship Canal (CSSC) in November 2011 by the U.S. Geological Survey. The study attempted to identify potential inflows of Des Plaines River water through the fractured bedrock that separates the two water bodies. Data include Rhodamine WT dye concentrations measured every 3 or 10 minutes
