What determines river visibility?

 I remember snorkeling in the swan river in mosman park around 5-7 years ago and the water was very clear. Recenty I tried it again but the water wasn't as clear as before. 

What makes the river clear and what makes it dirty? I'd like to go when it's clear again but when will that happen?

Strong tides have a lot to do with it plus temperature, turbidity and wind strengths

There is no way one can predict what you want
