Water velocities and discharge were measured in the lock chamber and immediately downstream of Brandon Road Lock on the Des Plaines River at river mile 286 on December 9-10, 2014 using Teledyne RDI Rio Grande 600 and 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with a differential GPS receiver with submeter accuracy. These ADCP measurements were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi River Interbasin Study (GLMRIS). Velocity measurements were processed using the Velocity Mapping Toolbox (Parsons and others, 2013) to derive temporally- and spatially-averaged water velocity values. Discharge measurements were processed with the QRev discharge...

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 the boxed stern of a rake hopper barge and the raked bow of a rake tanker barge (herein referred to as the rake-to-box junction gap) using two SonTek Argonaut SW 3kHz acoustic Doppler velocity meters (ADVM). One ADVM was mounted 0.091 meters below the water surface, facing downward in the center of the rake-to-box junction...

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 mount about 1 foot below the surface. The data collected in March 2010 had the sonde on a towed cable about 7-9 feet below the surface. All data have been edited and reviewed. Omitted data have been flagged with a data value of -9999 in the data files.

These data files include georeferenced water-quality data with associated time stamps (CDT) for basic water-quality parameters (temperature, specific conductivity, pH, and dissolved oxygen) for 13 stationary multi-parameter sondes in the vicinity of the lake water release structure. One stationary sonde also collected chlorphyll and turbidity data. These data were collected at 5 minute intervals. Cross-sectional water-quality data (basic water-quality parameters plus chlorophyll and turbidity) were also collected at three transect lines (40-50 feet wide) located in the outlet channel downstream of the structure at varying time intervals. All sonde probes were located approximately 1.5 to 2.5 feet below water surface....
