Water temperature data, in degrees Celsius, and specific conductance data, in microsiemens per centimeter at 25 degrees Celsius,(TC), were measured at U.S. Geological Survey streamgage 05536995 (Chicago Sanitary and Ship Canal at Romeoville, Illinois), near the Electrical Dispersal Barrier System (EDBS) in Romeoville, Illinois. The TC data were measured every five-minutes at four gage height levels above the gage datum (P1 = 21 feet, P2 = 17 feet, P3 = 13 feet, P4 = 9 feet). The gage datum is 551.76 feet above the North American Vertical Datum of 1988 (NAVD88). Five minute and daily mean TC data were downloaded from the National Water Information System and stored in a comma separated value files. The five-minute data file was labeled "05536995-WY2019-temp-speccond-five-minute.csv". The daily mean data file was labeled, "05536995-WY2019-temp-speccond-dailymean.csv". The 7-day moving average of the daily mean values were calculated in Microsoft Office Excel. For each day, the 7-day moving average was calculated as the average of the daily mean value for that day and the six previous days. This spreadsheet was saved as a csv file labeled, "05536995-WY2019-temp-speccond-7daymovavg.csv". The water year 2019 annual minimum, maximum, mean, median, and standard deviation were calculated for each of the four temperature and specific conductance probes in Microsoft Office Excel and saved as a csv file, "05536995-WY2019-temp-speccond-annualstats.csv". The csv files containing five-minute, daily mean, 7-day moving average, and annual statistics (minimum, maximum, mean, median, and standard deviation) for water year 2019 are stored as comma seperated value files stored in a zipped folder named 05536995-WY2019-temp-speccond.zip.
