Ok, I am a "why" person, so I have gotten no answers yet besides "why do you ask?". I am searching for some alpine rivers to hike into and fish. I just can see these huge trout just waiting for me. But wait, where do they come from? Are all lakes stocked if they don't run to the sea? How do I know there are fish there ( I imagine them). No one seems to know if all lakes are stocked or can I still find beautiful catches in remote lakes that are not in the book? And how did they get there? This, I am sure is a very basic question to some, but am I just imagining fat fish in remote alpine lakes? If not, who put them there, us or GOD? Not a religious question, just wanting to know before I hike in with gear and why, oh why and how did those huge fish in my dreams get there.
