We have a double one of these on the Taff in Cardiff also with no fish protection, be interesting to see how the running Salmon cope though at least they have a fish pass, the Durham one needs stopping immediately until they can protect the fish.
Fished closing day today, 2 hrs on the fly and 2 hrs on the spinner without a touch on either, so my seasons total is 2 small Salmon and about 8 small Sewin.
2014 catch return for the Taff was just nine Salmon, whether anglers cant be bothered to submit these important figures I dont know but...
Had an hour at Radyr yesterday on the 15' fly rod and as the rest of my season absolute pants, my worst year for migratory fish from the Taff.
Don't think I will bother with the Taff again for migratory fish.
