I've not fished it this year but if you fish off the steps and cast up towards the weir you will usually find the fish, you will also loose plenty of gear while you learn how to fish it so unless you make your own feeders be prepared to spend some cash.
The trick is to use a feeder which is heavy enough to stay where it lands and then don't move it.
When you get a bite or want to recast wind in the slack then lift the tip as high and as fast as you can to get the feeder up in the water and clear of the rocks.
This is a busy style of fishing, I use one rod and a front rest, the butt should be on your knee with your right hand holding it, the bites will be fast and if you are not on it you will be snagged, this is no place for two rods and you should be casting every few minutes to get some food down and get the fish competing.
Good luck.
PS, If you are staying after dark the fish move down towards the bridge but unfortunately the caravan site is a bit of a magnet for the local nutters who can be a pain.
