File Formats

WQ.FMT provides details of the water-quality file layout.

DMV.FMT provides details of the daily mean streamflow file layout.

Note that within each file there is one record for each date and time sampled except for the daily mean streamflow values where there is one record for each day of the month (31 records to a calendar year). The water-quality records are sorted by date, time, and ending date (which may be present for some biological data).

Also note that the instantaneous streamflow recorded at the time of water-quality sampling is stored in each of the water-quality data files, and is available for use in cases where water-quality and streamflow pairs are required (e.g., correlations between water-quality and flow).
