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.
