Appendix 11
GSD Stream Reach Characterization and
Evaluation Report
The Little Calumet River Stream Reach Characterization and Evaluation Report completed in October 2002 by Greeley & Hansen was used to identify the concentration of pollutants in the combined sewer overflows (CSOs) and in dry and wet weather in the West Branch of the Little Calumet River. The study area for this report stretched from Cline Avenue to Ripley Street with an additional sampling location on Deep River. Figure 1 shows the eleven (11) locations used for dry and wet weather sampling as well as the CSO discharge points. Figures 2 to 13 graphically show the sampling results of the parameters that overlapped with the sampling conducted as part of this Little Calumet River Watershed Management Plan. These six (6) parameters are only a small portion of the constituents that were sampled for as part of this 2002 study. The tables included at the end of this appendix are those taken directly from the 2002 report by Greeley and Hansen for the Gary Sanitary District. Each water quality sampling location (11 total) has a table presenting the dry weather sampling results and two tables showing the wet weather sampling results. There are also tables showing the CSO discharge parameters for each wet weather event sampled. These are also shown by each location having a table for both events.
