Fishfinder..
I've heard the mouth can be good. Personally, I've fished there loads. I still go there often because I like the place. But it really is shocking fishing! I've stood there for hours, early morning, afternoon, after dark, pushing tide, falling tide, springs, neaps, east bank, west bank, in the waves, in the channel, under the bridge, east wind, west wind, no wind - and nothing.
I think in all the years, I've had a small kob, a gurnard & some rays / sandsharks...
So: try a spoon for elf later on in the year, try a dropshot fast retrieve for leery & a slow dropshot for kob bounced along the bottom.
A good looking spot: park at the bluewater bay lifesaving club. Go in and get a beer. Then grab your stuff and walk out into the water - following the bank of the river out to sea. The bank goes out for a good long way - kind of curves to the right as you go out. When the tide pushes, you get water rushing over the bank and into the channel. Flick a dropshot onto the bank and let it get washed off into the channel, twitching it as you go....
let me know if you catch something!!
