Spatial distribution of Rhodamine WT dye concentration measured in the Des Plaines River and the Chicago Sanitary and Ship Canal, Chicago, IL in November 2011

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 by means of Turner Designs C3 and C6 fluorometers with internal dataloggers at three fixed locations on the Des Plaines River, in three groundwater monitoring wells, at two fixed locations on the CSSC, and from a mobile vessel in the CSSC.
