There's a whole load of options on the Wark's Avon at Harvington.
There's a weir and pumphouse complex at the bottom left of Anchor Lane, £5 I believe.
The very next stretch downstream is the Golf course ~ Both the above controlled by
Manor Farm fisheries
Next stretch downstream is
Anchor Meadow with its lock, island and weir at the very bottom of Anchor Lane, easy parking behind your peg, toilet block, camping, dogs allowed and you can fish the night. This is where I usually go with the missus and the dog for a summer weekend camp and barbel fishing. £7 a day (it says 12 quid for a 24 hour ticket - don't let the owner take both this and a further six for camping...!) The only problem with this stretch is that you can't get to the Fish and Anchor pub across the river by crossing along the top of the weir unless the water is very low, and when the water is very low, the fishing is ****!
Next stretch downstream is another Manor Farm fishery, a long straight stretch with a big pool at the bottom - Three meadows long and with drive on vehicle access the whole way.
Below this is the XXX stretch and it starts off in some deep woodland. Classic lower Avon water this - slow and smooth. £5 last time I fished it.
All the above hold very large barbel indeed. Also you can come into contact with some large shoals of small barbel, I had eight fish hooked in two hours last year.
The Severn has Montford Bridge, another pitch a tent and camp the weekend stretch but this time with a pub, the
Wingfield Arms Get your day ticket at the pub.
