File Extension Definitions

The name of each file is ssssssss.ttt where ssssssss is the 8-digit USGS station number, and ttt is:

ALK for alkalinity, bicarbonate, and carbonate parameters,
BIO for biological parameters,
DMV for daily mean values of streamflow,
MAJ for major dissolved ions,
MT1 for dissolved and total trace-element parameters,
MT2 for dissolved and total trace-element parameters,
MT3 for dissolved and total trace-element parameters,
MT4 for dissolved and total trace-element parameters,
NUT for nutrients, suspended sediment, and organic carbon,
PHY for physical/field parameters including instantaneous flow, and
RAD for radiochemical parameters.

File Formats

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).

Supporting Water-Quality and Streamflow Information

• Water-quality measurement-related files

• Station information files

• Measurement-accuracy data from the Blind Sample Program (BSP)
