Hi Gary
I have fished the lower (southern) section and managed a few very small trout and nothing to rave about, however when I've tried getting info previously on FFF and I got a similar result. Funny thing is many old timers swear by this little river and rarely venture away from it - only to tell me how good the Manifold is

. I can only assume they are too old for pc's or its a top secret venue

.
I'm considering trying it with a few friends tomorrow middle and top sections, if I can talk them into it, thats if it's not battered by the rain but I dont even know how badly rainfall affects the Manifold.
If we go, I'll get back to you
Mick
