Hi FH.
Do you have a boat/canoe? If not you may be limited to the mouth-end of the river and the Pont camp site only. (which is not bad)
I've had some success on small fish like pick handle barracuda, bar tail flat head, grunter, etc.
It is said that the upper reaches produces fair size cob. There are kingy's, bream, etc. as well and the river is also popular amongst fly fishers.
Only problem is water sports with power boats. Ski'ers, etc.
