The water temperature in degrees Celsius and specific conductance data in microsiemens per centimeter at 25 degrees Celsius (TC), measured at U.S. Geological Survey streamgage 05536995, located at Chicago Sanitary and Ship Canal near the Electrical Dispersal Barrier System in Romeoville, Illinois. The TC data are 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). Daily mean and five-minutes water temperature and specific conductance data were downloaded from the National Water Information System and stored in a comma separated value files. Daily mean data are stored in a comma separated value file, "05536995-WY2019-temp-speccond-dailymean.csv" and the five-minutes data in "05536995-WY2019-temp-speccond-five-minute.csv". The 7-day moving average of daily mean values was calculated in Microsoft Office Excel spreadsheet. For each day, the 7-day moving average was calculated as the average of daily mean value for that day and the six previous days. This spreadsheet was saved as a csv file, "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 probes and the four 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 can be downloaded from this page.
