Rhodamine WT dye concentrations measured at fixed locations in the Des Plaines River near Brandon Road Lock and Dam near Rockdale, Illinois (October 20-21, 2015)

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 concentration downstream collected by these instruments capture the leakage of dyed water from the lock, the pulse of dyed water exiting the lock during routine emptying of the lock, and the mixing of the dyed water downstream during a 17-minute flushing operation of the lock. The fluorometers were installed on both sides of the approach channel to the lock at five fixed locations approximately 1.5 to 4 feet below the water surface depending on the location. Fluorometer readings were taken at a frequency of 1 measurement every 30 seconds. Mooring of barges and active barge traffic led to some contamination of fluorometer data by increasing local turbidity concentrations near the active vessels. These data have been screened out during processing. The C3 turbidity sensors were not calibrated and therefore reported only relative changes in background turbidity and not absolute turbidity values (in relative fluoroescence  units (RFU)).

Spatial distribution of Rhodamine WT dye concentration measured in the Des Plaines River near Brandon Road Lock and Dam near Rockdale, Illinois (October 20-21, 2015)

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 Rhodamine WT dye during a routine filling procedure.  Measurements of dye concentration downstream collected by these survey boats capture the leakage of dyed water from the lock, the pulse of dyed water exiting the lock during routine emptying of the lock, and the mixing of the dyed water downstream during a 17-minute flushing operation of the lock. The fluorometers were installed in a fixed, downlooking orientation approximately 1 foot below the water surface. Fluorometer readings were taken at a frequency of 1 measurement per second. Data were acquired on personal computers running Tera Term to log serial communication from the fluorometers.  Raw (not georeferenced) data were stored internally on the fluorometers and downloaded following the survey. Survey techniques included streamwise transects through the dye plume in both the upstream and downstream direction, serpentine surveys, and near-bank surveys to capture the full spatial distribution. The boat survey crews also performed periodic, simultaneous discharge measurements at key locations in the approach channel to the BRLD and further downstream near the intakes and outfall of a power plant. Mooring of barges and active barge traffic restricted surveys in some locations and led to some contamination of fluorometer data by increasing local turbidity concentrations near the active vessels. These data have been screened out during processing. The C3 turbidity sensors were not calibrated and therefore reported only relative changes in background turbidity and not absolute turbidity values (in relative fluoroescence  units (RFU)).

Water surface elevation in the Brandon Road Lock chamber near Rockdale, Illinois (October 19-21, 2015)

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 the dye study to capture the lock operations leading up to and following the dye study. The instrument was deployed within conduit placed inside the ladder well near the 500-foot station on the right wall of the lock chamber (when looking downstream). At the time of deployment, the Level Troll was calibrated to the water surface elevation readings (headwater elevation; upstream gates open) as measured by the U.S. Army Corps of Engineers at Brandon Road Lock and Dam.  On October 20, 2015, the lock chamber at BRLD was dyed with 4 liters of Rhodamine WT dye during a routine filling procedure.  After filling and dye concentration measurements in the lock were complete, the lock was emptied and followed by a 17-minute flushing operation of the lock. Water surface elevation measurements were taken at a frequency of 1 measurement every minute by the Level Troll. Data logging was stopped and the data were recovered on October 21, 2015.

Bifenthrin Absorption to Mesocosm Walls Resulting From the Delivery of a Bifenthrin Spiked Suspended Sediment

Direct and indirect ecological effects of the widely used insecticide bifenthrin on stream ecosystems are largely unknown. To investigate such effects, a manipulative experiment was conducted in stream mesocosms that were colonized by aquatic insect communities and exposed to bifenthrin-contaminated sediment; implications for natural streams were interpreted through comparison of mesocosm results to a survey of 100 Midwestern streams, USA. In the mesocosm experiment, direct effects of bifenthrin exposure included reduced larval macroinvertebrate abundance, richness, and biomass at concentrations (EC50s ranged 197.6 – 233.5 ng bifenthrin/ g organic carbon) previously thought safe for aquatic life. Indirect effects included a trophic cascade in which periphyton abundance increased after macroinvertebrate scrapers decreased. Adult emergence dynamics and corresponding terrestrial subsidies were altered at all bifenthrin concentrations tested. Extrapolating these results to the Midwestern stream assessment suggests pervasive ecological effects, with altered emergence dynamics likely in 40% of streams and a trophic cascade in 7% of streams. This study provides new evidence that a common pyrethroid might alter aquatic and terrestrial ecosystem function at the regional scale.   
This data file contains data on the absorption of bifenthrin to the mesocosm walls. A bucket was cut up into identical sizes and placed into mesocosms. The bucket pieces were removed at different times throughout the experiment. The bucket pieces were rinsed with methanol and then analyzed for bifenthrin. Duplicate measurements were made for various time periods over 24 hrs.

Spatial distribution of layer-averaged velocity measured in the Calumet Harbor, Illinois (March 25, 2016)

Acoustic Doppler current profiler (ADCP) data were collected along a prescribed navigated course throughout Calumet Harbor on March 25, 2016 to determine the spatial distribution of layer-averaged velocities. The data were layer-averaged in 2-foot increments of depth from the bed to the water surface, and temporally-averaged over a 30-second window to reduce noise. Data were processed using the Velocity Mapping Toolbox (Parsons and other, 2013). Any data assigned a value of "-9999" are invalid or missing and should not be used for analysis.
