Don't know if means anything, but my adopted cousin, Chris, went fishing like a week and a half ago, at a creek just down from my aunt's house, and he said that he caught 20 rainbows, the biggest being around 12" long. He kept his limit to eat.
Every other Thursday at Beavers Bend in Oklahoma they release trout into the river/lake. You are only allowed to keep 5 a day and it has to be the first five you catch. NO catch and release. I was going to go but haven't had the chance to. Maybe I can in a couple of weeks.
