The highest environmental score was achieved when the translucent release was applied all year, followed by May to February (inclusive), July to February, and then July to March. As expected, the highest total diversion occurred when there was the smallest translucency window, of October/November to January. A translucency window of approximately
180-2200 ML/d achieved the highest environmental scores. Both the environmental score and total irrigator diversion were relatively insensitive to both lower and upper thresholds, except for the lowest environmental scores.
