Estimated – a manual change has been made to the data with confidence.

Suspect – a change cannot be made but the data is felt to be inaccurate.

Unchecked – raw input data that has not been inspected manually.

Missing – data has been deleted or never arrived in the archive.

Percent valid – the percentage of 15 min (instantaneous) flow data available to calculate the daily mean.
