NOTES: 1) The locations of some of the water temperature sampling sites in the file "AllTemperatureData.mdb" were updated April 26, 2002. Several tables were also added to this database, but the data were not changed. 2) The Microsoft Access files "AllTemperatureData.accdb" and "TemperatureContacts.accdb" were originally older Access .mdb files. Because .mdb files cannot be read by Access versions 2010 and later, the files were converted to .accdb format in September 2016. The time stamps of the new .accdb files were made to match the time stamps of the original .mdb files.
