I would love to know what the condition of the Cooks really is!
I have watched that river for 45 + years and it is in the best condition I have ever see it!
Yes there is of storm water run off from many suburbs close to the City but we did a run up stream ?? 4 - 5 Kms, and although water was darkish it was clean.
There were Kingfishers working the banks (pretty birds) + many other sea birds, and bait fish galore. The schools of tailor and Mullet were large. Tailor a pain in the arse those little chopping @#%@@@!.
Funny how a place can get a bad name.
All that said give me a CLEAN waterway like the hacking any day.
