QC2 The Bad news First

A causeway across Lake Colac is needed to save it from dying.   A causeway bank provides a way to provide the deep water that has never been reliably there before.  It’s time to do something about Lake Colac, and for the first time in our history, we can.  
This sort of feature will still occur when the northern part of the lake dries out 



Sure we can keep raising the exit levels at Meredith  Park,  but the swamp effect will increase as vegetation takes over from around the edges , as less and less runoff comes in ; The shallow water and rich nutrients drive  rooted plants to thrive ( picture of grassy beach near the boat ramp ) Deep water, by its very nature,  becomes less fertile   . As many have said, there will be some visual and audible impacts from a causeway bypass and there is a need to ensure new water bodies do not generate algal blooms too easily.  The actual location and development of any causeway basin works will require a lot more planning to make sure the outcome is the best possible one for all concerned. New beaches, pipes, deep water holes  must be designed to work well without much maintenance ;--the nature of sustainable systems. Everyone of us has questions so ask them here.
