The lake has turned a horrible brown/green colour after the recent rains with the latest algae levels still trending upwards. While ongoing catchment management problems have contributed, clearly the input from the canal has been a major contributor. The photo below shows the chocolate brown polluted water in the adjacent canal.
With no flow control, this dirty and most probably high nutrient water can enter the canal at any time given the right conditions. Last week the conditions were right with the canal levels swollen with floodwaters AND the highest king tide for 2020 forcing large amounts of canal water into the lake! The brown waters add to the already poor water visibility, reducing light to the struggling underwater aquatic vegetation further degrading the lake.
As the algal blooms again form along the shoreline the big question is “how much irreparable damage has this caused”
