carp crazee. Why dont you just go and fish the place? Doesnt look like many okes have been there. I would say to be safe just fish during the day there.
I would take a can of KOO maize and some fresh bread for hookbaits, and a bag of plain meiliebomb. KOO maize i've found works very well when fishing a new place in Jhb.
Give it a go!
Good luck!
