Break of Season
The break of season represents the period of change from the low flow season to the medium/high flow season, generally considered to be between the start of May and the end of June (commonly referred to as the transition 1 season). In order to identify the point at which the season breaks, a threshold value was identified by looking at the average inflection point of the cumulative flow plots for the two key flow monitoring stations. The cumulative flow calculation excluded flow from January through March to exclude the impacts of large summer storms.
As with the low flow calculation, the threshold value for the individual zones was apportioned by the total catchment area. The break of season value was reported as the number of days after the first of April that the cumulative flow (from the start of April) reached the break of season threshold for each zone.
