I've been hearing alot of complaints from guys who have been there about snags in the water....resulting a lot of lost fish, traces getting broken off. When the water was low before the floods there was alot of grass and shrubs, so guys will be fishing straight into that morass....but I don't know about further down from the bridge....might be better there.
The terrain at the Nature Reserve can get a bit uneven, I guess you will just need to go see for yourself....but I figure you should be okay IF it doesnt rain too much....
