This data release is the update of the U.S. Geological Survey - ScienceBase data release Bera (2017b), with the processed data for the period October 1, 2013, through September 30, 2016. Watershed Data Management (WDM; Lumb and Kittle, 1986) database file WBDR13.WDM is updated with the quality-assured and quality-controlled meteorological and hydrologic data for the period October 1, 2013, through September 30, 2016, following the guidelines documented in Bera (2017a) and is named as WBDR16.WDM. The complete list of datasets in WBDR16.WDM database and the detail attributes of each of these datasets is given in table 1. Meteorological data other than precipitation (wind speed, solar radiation, air temperature, dewpoint temperature, and potential evapotranspiration) are copied from ARGN16.WDM and stored in this WDM file. Bera and Over (2017) describes the processing of the meteorological data in the database file ARGN16.WDM. The complete list of missing period of the precipitation data and the nearby stations used to fill in those missing data during the period October 1, 2013, through September 30, 2016, is given in table 2. The list of snow affected days of precipitation data and the missing and estimated period of the stage and flow data in WBDR16.WDM database during the period October 1, 2013, through September 30, 2016, are given in USGS annual Water-Data Report at https://wdr.water.usgs.gov. To open WBDR16.WDM file user needs to install any of the utilities described in the section "Related External Resources" in this page.
