title: Watershed Data Management (WDM) Database (SC22.WDM) for Salt Creek Streamflow Simulation, DuPage County, Illinois, January 1, 1997, through September 30, 2022

description: This data release (DR) is the update of the U.S. Geological Survey - ScienceBase data release Bera (2023), with the processed data for the period October 1, 2021, through September 30, 2022. This data release describes the watershed data management (WDM) database SC22.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 Salt Creek watershed in DuPage County, Illinois, as described in Bera (2014). Hourly precipitation and hydrologic data for the period October 1, 2021, through September 30, 2022, are processed following the guidelines described in Bera (2014) and Murphy and Ishii (2006) and appended to SC21.WDM and renamed as SC22.WDM. 

Meteorological data (wind speed, solar radiation, air temperature, dewpoint temperature, and potential evapotranspiration) are copied from ARGNXX.WDM and appended to SCXX.WDM. XX represents last two digits of a water year (WY). A WY is the 12-month period, October 1 through September 30, in which it ends. 

Errors have been found in each of ARGNXX.WDM prior to WY23. SCXX.wdm contains erroneous meteorological data and related flag values until WY21 thereby. 

Meteorological data (wind speed, solar radiation, air temperature, dewpoint temperature, and potential evapotranspiration) from January 1, 1997, through September 30, 2022, are copied from ARGN23.WDM and uploaded to SC22.WDM. 

Bera (2024) describes the processing of the meteorological data in the database file ARGN23.WDM and Bera (2023) describes the processing of SC21.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 SC22.WDM. DSN 107 and 801-810 are updated with the data through September 30, 2022. Data in DSN 5400 (water-surface elevation at the quarry) and 5700 (water surface elevation at Thorndale) are copied and updated through September 30, 2022, 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, 2021, through September 30, 2022, is given in Table1.csv. This file is in the comma separated values (CSV) file format and can be downloaded from this landing page. The list of snow affected days of precipitation data and the missing and estimated period of the stage and flow data in SC22.WDM database during the period October 1, 2021, through September 30, 2022, are given in the USGS annual Water Data Report at https://waterdata.usgs.gov/nwis.

To open the WDM database SC22.WDM user needs to install Sara Timeseries Utility, listed in the section "Related External Resources" on this page. Table1.csv can be opened with any text editor or Microsoft Excel.
