Like I said I caught a fish that looked exactly like that, on the same system yesterday morning before work (mine was about 4# -a big one). When you see the whole fish, it is clear that it is a king. Stam is also correct about the way the silver jacks look this time of year, they don't have any spots at this point really, and are just black/grey over white. I will try and dig up some pictures tonight at home for proof.
