Not as bad as it may look
I hope the water is starting to clear now, with the current respite from the rain, but even if it still resembles NAAFI tea, you can still enjoy some good sport. This is one of a nice set of Browns caught by a certain celebrity member on a #16 Hydro Caddis Nymph a few days ago at Trottenden.
There have been a number of beautiful Browns like this caught this year, and they may well be wild, so we can look forward to even better sport in future (so long as they are returned).
There were also a couple of nice Rainbows rising there the previous day, so they must have better eyesight than I have to see a tiny Shuttlecock Buzzer on the surface. It's still worth trying some dries even if the water is murky, so don't give up hope.
