I have read frequently in reports by the DWR that most rainbow trout planted in most of our reservoirs only live about 3 years. Apparently, when they go past this point, they cannot make the transition to a piscivorous diet efficiently and die. Perhaps you have encountered an example of what happens to these bigger bows. I have heard that the "3 yr old" problem has been really frustrating to the biologists and is why they have been working at times with the Gerrard strain/Kamloops bows to have available a more piscivorous, longer living bow they could plant here.
