A determination for each site as to when the stream was flowing and when it was not is made. For water temperature and conductivity, bad data is deleted. Variable shifts are determined based on field calibration measurements, and other indicators. Cases of water temperature below reasonable values are set to lower limits. A quality code is assigned to every value.
Survey data is reviewed to compute weir elevations and datum corrections.
All corrections and ratings are run against the good stage data to compute the discharge at each recording interval. A quality code is assigned to every value. Samples and monitoring activities have occurred in Taylor Valley each austral season since the 1993-1994 season. Samples were taken throughout the flow period on each stream. 1997-98 season data for Crescent Stream was bad.
