I'd avoid going into that creek. The bridge crossed Brennans Ck which is the overflow from the West Cliff Colliery tailings dam further up the creek (nice green colour: https://goo.gl/maps/BEpVY). It is very polluted with all the shit run-off from the coal mine. Last time I was out riding around there the creek was a deep green colour and smelt very bad....its only the water option .
