Adam,
I fish Stockton and the little sac river constantly, as matter of fact I just got back and managed to catch my limit of channels in the river. I have caught many catfish that were not flatheads that were in the 15 to 20 pound range, and a few that have been easily over 30. I have always considered them to be blue catfish, and if they were channels then I would of caught a handful that would of beat the current state record that stands at 34 pounds. Is it possible that their were blue cats in the sac river system before the dam was built? I was just wondering how MDC determines that there are not any in the lake. Thank you for all the information that you have already provided. I have attached a picture of a catfish that I thought was a blue and was caught in Aldrich.
Thanks,
Mitchell
