Station Name	River Name	Easting	Northing	Date	Five-day Mean Flow (m3/sec)a	Days below Q95b	Q95 (m3/sec)c

^a Fiveday Mean Flow (m3/sec) We use a rolling five-day average of the mean daily flow as a reference rather than the instantaneous flow rate at a station to avoid very short-lived increases in flows that would not be considered sufficient recovery.

^b Days below Q95This is the number of consecutive days the five-day average flow has been below the Q95 level (an indicator of low flow).

^c Q95 Q95 is considered a low river flow. It is the natural flow that would, on average, be exceeded for all but 18 days in a year, but rarely consecutively. When flow is prolonged below this level impact on the aquatic environment will occur.
