Howzit
I was at bronkies last week and the grass situation is really bad, but not on the sides of the dam, it is in the actual water where there are huge chunks of grass in water which is 2m+ deep, it made it very difficult to get to the right spots for bass, the great advantage was that in those huge patches of grass, there are alot of huge grass carp, they were practically swimming right past me on the boat, so i have just changed my tactics next time, to rather go and try to get a grass carp or two!
Hope i could help.
Cheers
