Figure 3: Example of an ACTogram for Summer Rearing and Growth bioperiod for Eightmile River. The durations on the Y-axis represent time in days for which flows have been below the level indicated on the X-axis. The colored areas indicate if the event duration should be considered typical (green), persistent (yellow) or catastrophic (red). The dashed lines and light shaded area indicate an estimated thresholds leading to the lowest flow on record. The stars indicate for how long were the flows under specific value (eg. 4 cfs) on August 31, 2005 for two different scenarios (present and reference conditions). The increase in number of stress days represents the impact at any given flow level.
