What happened to the Big Browns at the Gorge?

I was told, but don't recall exactly. Seems like it was a combination of cold water most of the year (less active fish), and lack of forage (crawdads and not much else). However, I'm sure there's other lakes in the same situation that grow larger ones, so I'm not sure on this one. Could be other factors. The bass guys might know.
