Watershed Data Management (WDM) Database (SC18.WDM) for Salt Creek Streamflow Simulation, DuPage County, Illinois, January 1, 1997, through September 30, 2018

This data release is the update of the U.S. Geological Survey (USGS) - ScienceBase data release Bera (2019b), with the processed data for the period October 1, 2017, through September 30, 2018. This data release describes the watershed data management (WDM) database SC18.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and discharge) are collected at USGS streamflow-gaging stations in and around DuPage County, Illinois. Hourly precipitation and hydrologic data for the period October 1, 2017, through September 30, 2018, are processed following the guidelines described in Bera (2014) and appended to SC17.WDM and renamed as SC18.WDM. Meteorological data (wind speed, solar radiation, air temperature, dew point temperature, and potential evapotranspiration) from October 1, 2017, through September 30, 2018, are copied from ARGN18.WDM and appended to SC18.WDM. Bera (2019a) describes the processing of the meteorological data in the database file ARGN18.WDM. Data in dataset number (DSN) 107 and 801-810 are used in comparisons of precipitation data. DSN 107 contains hourly precipitation data collected at Argonne National Laboratory at Argonne, Illinois. DSN 801-810 contains the processed Next Generation Weather Radar (NEXRAD)-Multisensor Precipitation Estimates (MPE) data from 10 NEXRAD?MPE subbasins in the Salt Creek watershed as described in Bera and Ortel (2018). Data in these DSNs are not quality-assured and quality-controlled. The data are downloaded and uploaded daily into a WDM database that is used for the real-time streamflow simulation system. Data from DSN 107 and 801-810 are copied from this WDM and stored in SC18.WDM. DSN 107 and 801-810 are updated with the data through September 30, 2018. Data in DSN 5400 (water-surface elevation at the quarry) and 5700 (water surface elevation at Thorndale) are updated through September 30, 2018, similarly (Murphy and Ishii, 2006). The complete list of missing precipitation data periods and the nearby stations used to fill in those missing periods from October 1, 2017, through September 30, 2018, is given in the table, missing_data (available in pdf and Microsoft Word formats). The list of snow affected days of precipitation data and the missing and estimated period of the stage and flow data in SC18.WDM database during the period October 1, 2017, through September 30, 2018, are given in the USGS annual Water Data Report at https://waterdata.usgs.gov/nwis.
