The waters that you meniton in the Redding article may rquire barbless flies, but I haven't heard that all of CA is under that restriciton. Since I always fish w/ barbless flies anyway, I haven't looked specifically for that requirement in the reg's but I doubt that this is true; I could be wrong, though.

You certainly are right that Redding is a great little town and that there are some spectaculur fishing waters in the area.........................
